I've just in the process of generating a HTML-formated report of
various pieces of information in the knowledge base (as well as adding
some more rule checking ... check reference in latest
file://ftp.netcom.com/pub/lynn/rfctest2.html as to differences between
what I've generated and the same information in rfc1600.
A simple example is the term index now in rfctest2.html. When loading
various glossories, I distinquish between term/phrases and acronyms.
The term/phrases have "relationships" built between them and their
corresponding definition(s). In addition there is a
Expands/Abbreviates semantic relationship between acronyms and their
corresponding term/phrases. In generating the term index, anytime
there is an "acronym" associated with a RFC title ... the
corresponding term/phrase is substituted (for the report).
Unfortunately, at this time, when an acronym maps to multiple terms
(i.e. BER maps to both bit-error-rate and basic-encoding-rules) there
is insufficient information to choose.
Of course it would be possible to write a rule that creates a new type
of semantic relationship between an RFC and a term ... and insert it
appropriately into the database (whenever a title "Contains" the
term/phrase/acronym). Another example would be to define non-term
phrases (somewhat in the class of acronyms) that map to an official
IETF term. One example would be the equivalence between the RFC title
series with "Privacy Enhancement for Internet Electronic Mail" and the
term "Privacy Enhanced Mail".
In any case, I've also been thinking about doing something similar
with the internet drafts ... fixing up a demon periodic check
ds.internic.net for new drafts and snarf them off as they appear,
suitably parse the drafts, and then do various rule checking and
report generation.

Reply-To: Lynn Wheeler <lynn at bli.com>
I've now updated rfctest2 with "standards" index and a "term" index
(in addition to the RFC index and the author index).
the standards index is effectively the rfc1600 information with
some modification (read prefix to the standards section)
the "term" index is a combination of acronyms and glossory terms found
in the titles of RFCs (for the output the acronyms were mapped to
their respective terms and RFC lists combined). this could
use some amount of work cleaning it up.
the file has grown by about 50kbytes to slightly over 500kbytes.
ftp://ftp.netcom.com/pub/lynn/rfctest2.html
note that ftp.netcom.com has a ftp/anon load limit. if actually
ftp'ing in, one would see a message about exceeding the limit and
possibly trying netcom1.netcom.com, netcom2.netcom.com,
netcom3.netcom.com, ..., &/or netcom13.netcom.com.

PRAGUE
is like a history lesson come true. As you walk among the long stone
palaces or across the 'Charles Bridge', with Smetana's Vltava flowing
below and pointed towers all around, you will feel as if history had
stopped somewhere back in the 18th century. Goethe called Prague the
'prettiest gem in the stone crown of the world'. This cultural center of
Europe is famous for its architectural treasures that have been so well
preserved. Its wealth can be gathered from the diversity and quantity of
the many Romanesque monuments and its Gothic town planning. In time new
styles developed, like Baroque and later on Art Nouveau. The countenance
of Prague reflects every cultural period and all the different artistic
styles.
Musical life is a deeply rooted tradition in Prague. One only needs to
remember the names of the two greatest Czech composers, Antonin Dvorak
and Bedrich Smetana. Their music can still be heard. It is said that it
is an advantage to be a foreigner in Prague. The renowned Slavonic
hospitality manifests itself in Prague at every step. A lot of traditional
Czech products are offered, like crystal, porcelain, earthenware, but also
CDs, and illustrated art books. The national beverages like beer and
sliwowitz are worth a try and restaurants offer a wide variety of food.
Prague is ready to welcome its visitors and let you share in the experience
of 'awakening to a beautiful dream'.

Subject: concept/term indexing (more than you ever wanted to know?)
Reply-To: Lynn Wheeler <lynn at bli.com>
I'm interesting in solutions to concept/term indexing. I've loaded
lots of the IETF/RFC information into our semantic network dbms and
have been producing data base reports rfcindex.txt and rfcauthor.txt
(available from ftp.netcom.com:pub/lynn) ... as well as running some
rules (i.e. knowledge base) one of which results in the stuff
included in section 6.10 of rfc1600 (std1).
Past couple days I've been experimenting producing a rfcindex.html
document (currently ftp://ftp.netcom.com/pub/lynn/rfctest2.html). The
issue that I'm looking at now is the mapping of keyword/terms/phrases
to concepts for the "concept" index. As part of this endevor, I've
also run/created additional rules as part of the "standards" process
index (resulting in 3 minor differences between the rfc1600 and
rfctest2.html ... as noted in rfctest2.html).
The IETF SNDBMS currently contains the glossary (mostly from rfc1392)
with "IETF terms" and acronyms ... with appropriate relationships
defined between acronyms and their respective "IETF terms". The "IETF
terms" also have the glossary definitions. I've also manually defined
some "peer-to-peer", reflexive "IsASenseOf" relationships between
"IETF terms".
Producing the rfc concept index (in the html file) ... it is fairly
obvious to merge the acronym and term lists into single reference.
However, straight keyword isn't sufficient (for example of additional
clustering/ordering see rfc1000). I would like to be able to manual
define additional hiearchical relationships (of the term/acronym
flavor) between IETF terms ... and additional relationships between
RFCs and IETF terms.
A simple example is "Privacy Enhanced Mail" and "PEM" are defined IETF
terms and acronyms. However, the RFCs on the subject use the phrase
"Privacy Enhancement for Internet Electronic Mail". I've looking for a
new category of "things" (other than defined terms) that can be used
in searches/matches. Each of these "phrase" things would have the
appropriate relationship back to a defined "IETF term".
I then have some code that matches word combos in titles with Terms,
acronyms, and (now) phrases (where both acronyms and phrases map back
to specific selected "terms").
It would probably be useful ... in addition to "terms", "phrases",
"acronyms" which are used when looking for their occurance in text
(titles, abstracts, keywords, etc) ... it would also be useful to have
something like "IETF category" ... that directly associates the rfc,
totally independent of the "words" ... again likely an effort
requiring manual creation.
The "opportunity" was addressed in NLM's Unified Medical Language System
(UMLS). By defining the following type of schema:
[semantic category]
[conceptid]
[termid]
[type of language]
[attribute]]
[stringid]
[attribute]
[string]
The conceptid, termid, and stringid are all "numerical indexes"
effectively used for RDBMS implementations. A [semantic category] will
have one or more [conceptid] ... in addition, a [conceptid] may have
relations to one or more [semantic category].
I've taken some amount of liberties loading the "relational ascii
table" data on the UMLS cdrom (500 mbytes) into our SNDBMS. Basically
a [termid] [attribute] is an attribute "preferred", "synonym",
"non-preferred", and "other" ... which effectively involves the type
of relationship from the [conceptid]->[termid] ([stringid] [attribute]
is similar). Taking liberties ... instead of (just) making [attribute]
an entity-attribute ... I've defined different types of relations
between [conceptid] & [termid] ... that effectively correspond to the
[attribute] and used them when inserting the data.
It is then possible to look for matches across all possible strings
and appropriate classify/index the recognized item (i.e. "UMLS" was
created by a "library" organization ... i.e. National Library of
Medicine ... and is used by Medlars ... the medical library system).

Extract from UMLS(r) Metathesaurus(r) Fact Sheet:
Includes 152,444 concepts and 311,046 terms (including lexical
variants, synonyms, etc) from fifteen different vocabularies. It
contains all terms from the 1992, MeSH(r), the National Library of
Medicine's Meical Subject Headings, DSM-HIR, the American Psychiatric
Association's Diagnostic and Statistical Manual of Mental Disorders,
Third edition (revised); .... and another 20 or so sources.

The Metathesaurus is organized by concept or meaning. Alternate names
for the same concept (synonyms, lexical variants and translations) are
linked together. Each Metathesaurus concept has attributes that help
to define its meaning. A number of relationships between different
concepts are represented. Some of these relationships are derived from
the source vocabularies; others are created during the construction of
the Metathesaurus. Most inter-concept relationships in the
Metathesaurus link concepts that are similar along some dimension.

The suggested "implementor's agreement" was that no mechanism produce
an output token more than 2k larger than the input token.

I would support both.
I agree. I also like John Linn's suggestion that we specify an
"implementor's agreement" that all mechanisms support at least a 2k
input token size. We may actually want to specify that in a future RFC
revision as a requirement.

Filename : draft-ietf-pppext-multilink-08.txt
Pages : 20
Date : 04/25/1994
This document proposes a method for splitting, recombining and sequencing
datagrams across multiple logical data links. This work was originally
motivated by the desire to exploit multiple bearer channels in ISDN, but is
equally applicable to any situation in which multiple PPP links connect two
system, including async links. This is accomplished by means of new PPP
options and protocols.

Title : SIPP Authentication Header
Author(s) : R. Atkinson
Filename : draft-ietf-sipp-ap-03.txt
Pages : 10
Date : 04/25/1994
This memo describes the SIPP Authentication Header (AH). This payload
seeks to provide integrity and authentication for SIPP datagrams.
Non-repudiation may be provided by an authentication algorithm used with
AH, but it is not provided with all authentication algorithms that might be
used with AH. Confidentiality, and protection from traffic analysis are not
provided by AH. Users desiring confidentiality should consider using the
SIPP Encapsulating Security Protocol (ESP) either in lieu of or in
conjunction with AH. This document assumes the reader has previously read
and understood the related "SIPP Security Architecture" document which
defines the overall security architecture for SIP Plus and provides
important background information for this specification.

Title : SIPP Encapsulating Security Payload (ESP)
Author(s) : R. Atkinson
Filename : draft-ietf-sipp-esp-02.txt
Pages : 11
Date : 04/25/1994
The SIPP Encapsulating Security Payload (ESP) seeks to provide
confidentiality and integrity by encrypting data to be protected and
placing the encrypted data in the data portion of the SIPP Encapsulating
Security Payload. Either a transport-layer (e.g. UDP or TCP) frame may be
encrypted or an entire SIPP datagram may be encrypted, depending on the
user's security requirements. This encapsulating approach is necessary to
provide confidentiality for the entire original datagram, but can be very
expensive to implement. Use of this specification will increase the SIPP
protocol processing costs in participating end systems and will also
increase the communications latency. The increased latency is primarily
due to the encryption and decryption required for each SIPP datagram
containing an Encapsulating Security Payload.

Title : Selecting a Direct Provider
Author(s) : Y. Rekhter
Filename : draft-rekhter-direct-provider-01.txt
Pages : 8
Date : 04/25/1994
Within the existing Internet routing architecture/protocols different hosts
within a domain (autonomous system) usually can't control the choice of
adjacent domains for forwarding of the inter-domain traffic originated by
the hosts. In this document we describe a simple mechanism that provides
hosts with such control. The proposed scheme can be realised with the
existing technology, off-the shelf components, and minor tweaking of
forwarding algorithm by border routers. The scheme doesn't require any new
routing protocols.

A New Internet-Draft is available from the on-line Internet-Drafts
directories.
Title : A Chemical Primary MIME Type.
Author(s) : H. Rzepa, P. Murray-Rust
Filename : draft-rzepa-chemical-mime-type-00.txt
Pages : 4
Date : 04/25/1994
This document indicates why we believe there is a need for a new primary
"chemical" MIME type. We outline the typical expected uses of such a MIME
type and propose a number of secondary chemical types.

In rfc1184 there is this text:
+ Normally, the entire user interface is left up to the implementor.
+ However, there is functionality that the user should be able to
+ specify on the client side of the connection. During a Telnet
+ session, the client side should allow some mechanism for the user to
+ give commands to the local Telnet process. These commands should at
+ least allow the user to:
+ 1) Change the mode of the connection. The user should be able to
+ attempt to turn EDIT, FLOW, TRAPSIG, and ECHO on and off. The
+ server may refuse to change the state of the EDIT and TRAPSIG
+ bits.
My question is about the last sentence above. I certainly can see how
it is good to require clients to attempt to negotiate these options
when the user requests. However, nowhere does this make clear when and
why a server might refuse these state changes.
To me, it seems clear that the server would refuse to negotiate those
options if they were in conflict with the present state of the "pty"
set by the application. For example, if the application has set the
pty into "raw" mode, negotiating remote edit should probably be refused.
(And I think I can make similar arguments about flow, trapsig and echo.)
Is it correct that a reasonable and compliant linemode server would
refuse mode changes in that way?

That might be one reason why a server might refuse changes. The server
is free to refuse changes for any reason, including the fact that it
doesn't support linemode --- or perhaps the way the server is
implemented, it isn't able to switch into linemode after the connection
is set up.

The suggested "implementor's agreement" was that no mechanism produce
an output token more than 2k larger than the input token.
Sorry, my mistake. I still think it would be a good idea to have a
minimum input token size that all mechanisms could support, though.

The goal of this section was to ensure that the client provided a way
for the user to make the request. It was assumed that the client would
turn the request into the appropriate telnet command.

On a typical UNIX based system, you can do things like "stty -echo".
This would change the state of the pty, which notifies the telnetd
of the state change, and it then sends a MODE command to the client
to let it know of the change. The telnet client interface allows
the opposite to happen. The client sends the MODE command to the
server, it takes the new mode and sends it to the pty, which then
becomes apparent to any application that looks at the pty state.
It was assumed that there might be some systems where the state
of the pty couldn't be changed by the server, and we didn't want
to make it impossible to implement linemode telnet on those systems.

The server shouldn't refuse to change the state of these bits unless
there is a valid restriction in the pty driver that precludes changing
them.

- On a typical UNIX based system, you can do things like "stty -echo".
- This would change the state of the pty, which notifies the telnetd
- of the state change, and it then sends a MODE command to the client
- to let it know of the change.
Sure.
- The telnet client interface allows
- the opposite to happen. The client sends the MODE command to the
- server, it takes the new mode and sends it to the pty, which then
- becomes apparent to any application that looks at the pty state.
So when should it look at its pty state? Before now there hasn't been
anything turning on and shutting off bits like "ECHO" and "ICANON".
The application isn't _notified_ when this stuff gets changed. And
applications shouldn't have to be changed to work with telnet.
If the application allows echo, then it seems perfectly fine if telnet
negotiates echo back and forth between local and remote. It doesn't
seem fine to me if the client can re-arrange virtual terminal behavior
my application has specified. It also doesn't seem right to me that
the application should see the "echo bit" off, just because echoing
is being done by the telnet client.
At least in the UNIX world, a process which continuously holds a
controlling terminal does not need to keep querying the terminal
modes: it is assured the system isn't going to change it.
I guess this means I'm unconvinced? :)

Mike said it correctly, having the telnet client able to

Normally it isn't real useful, and can (will) confuse applications
because they don't know that the state of the pty/tty has changed.

Oh my. By these statements it now becomes clear to me that you do
not have a clear understanding of how linemode works, and what
support is needed in the terminal driver on the server to allow
linemode to work.
The goal of linemode is to offload the input character processing
from the server to the client, without any noticable change to
the application that is attached to the slave side of the pty.
The meaning of the "echo", "isig", "icanon", "oxtabs", "ixany" bits
should not change as far as the application is concerned.
On BSD systems, this is acheived via the EXTPROC bit. This bit
is set by the telnet server when it is running in linemode. Most
of the input processing is then skipped, because it knows that that
has already happened externally (in the client).
The usage of the ECHO option can be especially confusing if you
don't think it through. When the server is WILL ECHO, it means
that the server will be echoing back any characters of the input
stream that need to be echoed back to the screen. When the server
is WONT ECHO, it means that the server will not be echoing back
any of the input characters, so the client will be responsabile
for doing any character echo back to the screen that needs to be
done.
So, with this in mind, with the EXTPROC bit set the terminal
driver on the server will never echo any characters, no matter
what the state of the "echo" bit in the tty. When the "echo"
bit is set in the tty, the server will negotiate "WONT ECHO",
which tells the client that it needs to do any terminal echo.
When the "echo" is off, the server will negotiate "WILL ECHO",
which tells the client that it should not do any terminal echo,
because the server will take care of any that needs to be done.
But the server doesn't do any echoing, so you get the effect that
you want, no terminal echo. When the application turns the "echo"
bit back on, the server negotiates "WONT ECHO" again.
As an example, here is what happens on a BSD system when turning
off and on various state bits in the tty, when telnet option
debugging is turned on:
% stty -icanon
RCVD IAC SB LINEMODE MODE TRAPSIG|SOFT_TAB
SENT IAC SB LINEMODE MODE TRAPSIG|SOFT_TAB|ACK
% stty icanon
RCVD IAC SB LINEMODE MODE EDIT|TRAPSIG|SOFT_TAB
SENT IAC SB LINEMODE MODE EDIT|TRAPSIG|SOFT_TAB|ACK
% stty -echo
RCVD WILL ECHO
SENT DO ECHO
% <typed "stty echo">
RCVD WONT ECHO
SENT DONT ECHO
% stty -isig
RCVD IAC SB LINEMODE MODE EDIT|SOFT_TAB
SENT IAC SB LINEMODE MODE EDIT|SOFT_TAB|ACK
% stty isig
RCVD IAC SB LINEMODE MODE EDIT|TRAPSIG|SOFT_TAB
SENT IAC SB LINEMODE MODE EDIT|TRAPSIG|SOFT_TAB|ACK
% stty -oxtabs
RCVD IAC SB LINEMODE MODE EDIT|TRAPSIG
SENT IAC SB LINEMODE MODE EDIT|TRAPSIG|ACK
% stty oxtabs
RCVD IAC SB LINEMODE MODE EDIT|TRAPSIG|SOFT_TAB
SENT IAC SB LINEMODE MODE EDIT|TRAPSIG|SOFT_TAB|ACK
% stty -ixon
RCVD IAC SB TOGGLE-FLOW-CONTROL OFF
% stty ixon
RCVD IAC SB TOGGLE-FLOW-CONTROL ON
% stty -ixany
RCVD IAC SB TOGGLE-FLOW-CONTROL RESTART-XON
% stty ixany
RCVD IAC SB TOGGLE-FLOW-CONTROL RESTART-ANY
The two features that need to be implemented in the terminal driver
on the server is:
1) The ability to turn off input character processing
(including character echo), by having the terminal
driver ignore those state bits (icanon, echo, isig,
etc.) In BSD this is done through the EXTPROC bit.
2) The application on the master pty side has to be
notified whenever the state of the pty changes, so
that it can negotiate the appropriate new state with
the client.
Without both of these features, you cannot do a transparent (to
the application) implementation of server linemode.

Subject: IPng Area Update
This is a quick update on the status of the IETF IPng effort.
Since the creation of the IPng area late last year we have been focused on
two primary tasks; developing a reasonable estimate of the projected
lifetime for the IPv4 address space and producing a draft requirements
document.
The IPv4 Address Expectations Working Group (ALE), chaired by Frank
Solensky and Tony Li reported during a session held at the IETF meeting in
Seattle that their current estimate was that the IPv4 address supply would
be exhausted in the year 2008 ( plus or minus 3 years), assuming no changes
in the basic rate of growth in the demand for addresses. Clearly, if there
were a request for a very large block (many millions) of addresses, it
would affect this estimate.
The Transition and Coexistence Including Testing (TACIT) working group,
chaired by Atul Bansal and Geoff Huston had its first meeting in Seattle.
This group will focus on the long term transition and coexistence issues
and will define recommendations for testing IPng specifications and
implementations.
Of course, the working groups for each of the IPng candidates have been
busy and did meet in Seattle to further refine the details of their
proposals.
The IPng Requirements BOF, chaired by Frank Kastenholz and Jon Crowcroft,
has produced a draft of an IPng requirements document. The current draft
is a refinement of an initial document by Frank Kastenholz and Craig
Partridge. It reflects input from a number of the white papers that the
IPng area solicited with RFC1550 and comments from the IPng directorate.
The requirements draft is ready for public comment. It has been published
as an internet-draft (draft-kastenholz-ipng-criteria-01.txt). We need
as many comments as possible by May 10. All interested
persons (that should be just about all reading this message)
should take a look at this document and, if you have comments or
suggestions, send them to the big-internet list. (Send a note to
big-internet-request at munnari.oz.au to subscribe.) You should also take a
look at the RFC1550 white papers, they have been published as internet
drafts. Look for any internet draft with "ipng" in its filename. All of
these documents are available at you favorite internet-drafts site and from
hsdndev.harvard.edu in pub/ipng/wp for anonymous ftp. Hsdndev also allows
gopher access.
The IPng directorate mailing list archives and directorate teleconference
minutes are also available from hsdndev.
We urge you to take a look at these documents and records. Let us know on
the big-internet list or in private mail what you think. This is an effort
that will effect us all and anyone who can help make the result better or
the transition easier is encouraged to participate.
Appended to this update is the area status report from the Seattle IETF
meeting.

IETF 29
IP: Next Generation Area Report
Seattle, Washington
Scott Bradner <sob at harvard.edu>
Allison Mankin <mankin at cmf.nrl.navy.mil>
Meetings of 4 IP: Next Generation working group, 3 BOFs, and an
open IPng directorate meeting were held during the 29th IETF meeting
in Seattle, Washington.
Address Extension by IP Option Utilisation BOF (AEIOU)
Reported by Peter Ford
Chair Brian Carpenter <brian at dxcoms.cern.ch>
Brian Carpenter presented the aeiou proposal (draft-carpenter-aeiou-00.txt)
and there was a lively discussion. Most people felt that aeiou would work
and could, with effort, be developed into a viable stop-gap solution.
There was one significant technical issue, the impact of option analysis
on local router performance. The main debate was whether the savings in
work and time to implement and deploy aeiou compared to a full IPng
solution were significant and worthwhile. There was a range of views on
this. The conclusion was not to propose an aeiou working group at this
time, but to document the proposal (possibly as an Informational RFC)
to keep it in reserve for future eventualities. Interested people
should contact brian at dxcoms.cern.ch.
Address Lifetime Expectations WG (ALE)
Reported by Tony Li
Chairs: Tony Li <tli at cisco.com>, Frank Solensky <solensky at ftp.com>
The ALE WG met to discuss its projections and future mechanisms for
improving the lifetime of the address space. Our current projections
were presented and subsequent discussion ensued. As a result, ALE
will also begin to track routing table sizes. We have volunteers to
collect data for us. We discussed address efficiency and have a
volunteer to produce a document on improving address space efficiency.
RFC 1597 was presented, and was thought to be very helpful. We
discussed the timetable for IPng, but were unable to come to any
reasonable conclusions due to uncertainty about the deployment of CIDR
and the explosion of the routing tables.
Common Architecture for Next-Generation IP WG (CATNIP)
Reported by Robert Ullmann
Chair (pro tem) Robert Ullmann <robert_ullmann at lotus.com>
WG meeting was chaired pro-tem by Robert Ullmann, as Vladimir
Sukonnik was unable to attend. Robert did a small soapbox on
the proper scope of the IPng proposals. This was followed by
discussion of a number of minor technical issues identified
recently on the CATNIP list. Several IPX related issues were
left uncertain. The issue of TUBA TCP and UDP checksums to be
discussed with the TUBA WG. DNS issues to be resolved in a near
future revision of the Collela/Manning draft which will be used
by both TUBA and CATNIP. Fragment translation was discussed, with
the differring semantics between CLNP, IPv4, and SIPP making it
less useful than would be expected.
IPNG Requirements WG (NGREQS)
Reported by Frank Kastenholz
Chairs Jon Crowcroft <J.Crowcroft at cs.ucl.ac.uk>,
Frank Kastenholz <kasten at Research.Ftp.Com>
The working group had a number of presentations from members of the
community who are experts in particular technical areas. These included
Mike StJohns on Security, Greg Minshall on Mobility, Dave Clark on Network
Services, Lixia Zhang on RSVP, Mark Handly on AVT, Peter Ford on
Backbones, and John Curran on Market Needs. The intent was to give the
group background information on these particular areas and their specific
needs -- similar to the White Papers solicited by the Directorate.
The working group then proceeded into a lively and spirited debate on the
various criteria. The community suggested many significant improvements
which are still being digested by the chairs and authors. One important
improvement that seemed to have great support from the community was that
the requirements should be strengthened amd made firmer -- fewer "should
allows" and the like and more "musts".
SIPP WG
Reported by Bob Hinden
Chair Bob Hinden <Bob.Hinden at eng.sun.com>
March 1994 IETF
The SIPP working group held a implementors meeting on Sunday afternoon
and two working group sessions on Wednesday and Thursday.
Bob Hinden presented a summary of recent working group activities. This
included that the SIPP charter had been approved, the SIPP Whitepaper had
been completed on time, a summary of the SIPP specifications which had
been completed since the last IETF meeting, and the SIPP specifications
which were submitted to the IPng area directors for publication as
experimental RFC's. Also presented was the announcement that Mosaic
pages had been created for the SIPP working group. These can be found at
http://town.hall.org
Jim Bound presented a summary of the implementors meeting. A number of
SIPP implementors had attended and several refinements had been made to
some of the SIPP options based on implementation experience. These
changes will be documented in an update to the SIPP specification.
Steve Deering presented an overview of the changes from last fall's SIP
spec to the current SIPP specification. This included details on the
layout of the Flow ID. Ramesh Govindan and Sue Thompson presented the
current approach for dealing with auto configuration and discovery. This
resolved the issues that were outstanding with the current drafts. New
specifications will be published.
Bob Gilligan presented an overview of IPAE. This resulted in a
discussion of some of the details of IPAE and uncovered a bug. There was
general agreement that IPAE needs to be simplified. This will be worked
on and the specification will be updated.
The Transition and Coexistence including Testing (TACIT) BOF
Reported by Geoff Huston
Chairs: Geoff Huston <G.Huston at aarnet.edu.au>
Atul Bansal <bansal at lkg.dec.com>
The BOF discussed the issues relating to transition and coexistence
in general terms as they relate to the constituency of the Internet, and
also discussed the specific issues relating to potential IPng transition
environments. The view was expressed that the characteristics and potential
timeframe of transition, coexistence and testing processes will be greatly
influenced through the interplay of market forces within the Internet, and
that any IPng transition plan should recognise these motivations and provide
ample levels opportunity identification to encourage the broad Internet
constituency to subscribe to the transition process (and therefore undertake
to meet the associated deployment costs of such transition).
The group decided to recommend to the IPNG Area Directoriate to form a
Working Group to explore the generic issues of the IPng transition process
and gather experience from previous technology transition that have occured
both within the Internet and within related networking technologies. A draft
charter was reviewed, with the view that this Working Group work would
contribute to the IETF IPng process by identifying these issues and reviewing
IPng transition plans at the appropriate phase of the IPng process.
TCP and UDP with Big Addresses (TUBA) WG
Reported by Peter Ford
Chairs Peter Ford <peter at goshawk.lanl.gov>
Mark Knopper <mak at aads.com>
Dave Marlow presented an update on the status of CLNP multicast. His
Internet Draft is intended to be multicast routing protocol independent,
and was presented from the ES viewpoint. Discussion ensued as to whether
the complexity of the network-to-data-link address mapping protocol was
worthwhile. The "extra hop" problem is widely viewed as being a
show-stopper and Dave presented an approach to address this problem and will
be updating the ID to reflect this.
Lyman Chapin updated the group on the electronic availability of the
pertinent ISO standards. Lyman is now comfortable
posting these documents as I-Ds and the network layer protocols (CLNP,
IS-IS, ES-IS and IDRP) will all be published by the end of the Seattle
IETF.
Dino Farinacci gave a short presentation on the status of Protocol
Independent Multicasting (PIM) in the IDMR working group. He noted there
would be little difficulty in using PIM for multicast routing of CLNP.
Ross Callon presented his work on flows in CLNP. In this scheme the
source NSEL is used to demultiplex flows between a single host pair.
The size of this field (eight bits) was a source of controversy and there
was concern that using the Source NSEL might cause to non-TUBA CLNP
entitities.
Dave Piscitello gave an overview of the current TUBA transition document.
Bob Brenner from GTE gave an overview of Cellular Packet Data Network
(CDPD). CDPD is using CLNP as an underlying protocol, but it can support
mobile hosts that are either CLNP or IP speakers.

I can definitively say that the routes did not fall back, based on
observation of 6 traceroutes a minute.
Is there a latency in the gated, so that no route is in the routing
table during a transient?
By what I observed, we went from routing through MAE-EAST, then no
route at Merit ENSS, then routing to MAE-EAST (but no reply after that
point), to routing through again.

It is a very poor definition of working, and not compatible with what is
expected from an IP routing protocol.
Noting that there are 2389 entries between these two nets alone, aren't
we backing into a corner where hand configuring these policy tables will
be intractable?
I will note that there are T1 inter-connections between AN_S and PSI in
at least two places here in Michigan. Why aren't these in the table for
Heartland sites? What about the probably hundreds of other multi-homed
sites?
Sounds to me like policy routing is already out of its depth, and we
should abandon it in favor of something dynamic.

Subject: Questions regarding GGS/Kerberos names
Cc: gssapi at ocsg.com
Reply-To: dpg at ocsg.com
I have some questions regarding the specifications contained in
Section 2 (Name Types and Object Identifiers) of the March, 1994
Kerberos Version 5 GSS-API Mechanism draft RFC.
* Section 2.2 describes the GSS name form in terms of a Kerberos
principal. Section 2.2 seems to provide utility for a developer
working at both the GSS and Kerberos API layers. Such cases should
be infrequent and raise questions regarding circumvention of GSS or
mechanism integrity.
To pass a Kerberos principal to gss_import_name() it must be
encapsulated in a gss_buffer. This raises the question: what is the
gss_buffer's length? Further, it implies the gss_buffer cannot be
deleted using gss_release_buffer().
What is the benefit of the GSS name form described in Section 2.2?
* Section 2.3 describes the GSS name form: service at hostname.
How is Kerberos realm information included in the form described in
Section 2.3?
* Section 2.4 appears to be no different than Section 2.1.
Are sections 2.4 and 2.1 different and if they are different that
what are the differences?
* Sections 2.5 and 2.6 describe a GSS name in terms of a UID (user
ID). Those specifications seem tailored to a UNIX environment. My
questions regarding the forms described in Sections 2.5 and 2.6 are:
* If the environment is DOS, NT, or a Mac then what is a UID?
* How is Kerberos realm information included in the UID forms?
* What utility do Sections 2.5 and 2.6 provide that section 2.4
does not provide?
Section 2.5 appears to have the same problems as Section 2.2
regarding buffer length and deletion.
Kerberos has several principal types but only three are commonly
useful to an application developer: KRB5_NT_PRINCIPAL,
KRB5_NT_SRV_HST, and KRB5_NT_UNKNOWN. Section 2.1 addresses the
Kerberos principal type KRB5_NT_PRINCIPAL. Section 2.3 addresses the
Kerberos principal type KRB5_NT_SRV_HST. I see no section that
addresses the Kerberos principal type KRB5_NT_UNKNOWN. (The most
common use of KRB5_NT_UNKNOWN is as a parameter to
krb5_sname_to_principal() indicating the host name is not to be
canonicalized.)
Since GSS/Kerberos names can be commonly expressed in three Kerberos
principal forms (KRB5_NT_PRINCIPAL, KRB5_NT_SRV_HST, and
KRB5_NT_UNKNOWN) then why not specify only those three forms? The
remaining forms such as UID translation can be provided in OS
specific libraries.
(I would appreciate responses to this message be CC's to me. I have
been removed from the cat-ietf mailing list. Why? I dunno. I have
sent requests for subscription.)

Subject: Internet connectivity in the Costa Rican jungle?
I'll probably get flamed for asking this here, but I honestly could not
think of a better place.
Problem:
A group of researchers working in a remote area of Costa Rica
would like email connectivity to the Internet. Currently they drive 5
hours to a small town where they share a FAX machine with about 80
other people. They could use a slightly higher bandwidth communication
channel. Apparently there are no phone lines anywhere near their
location.
Also, since this is not a commercial project, money is an
issue. (so running a fiber optic cable across the country or having
phone lines installed is not possible).
I thought real hard about this but most of my experience is
with ethernet, modems and leased lines. Even the spread spectrum
wireless devices I've seen will only do line of sight for about 10
miles (or less).
Does anyone have any experience with VSAT? We can skip over
the know problems with satellites (half-duplex + very long turn around
delays). I'm just curious if this is a solution at all i.e. can one
buy a small aperture dish + box and pump IP though it on a research
budget.
Does that "satellite cell-phone in a brief case" I saw in the
Steven Segall movie really exist? (the one where the ship's cook
saves the world from nuclear winter) Can I run a modem through it?
(even at 1200 baud this would be a win). I'm only half joking here -
I seem to recall seeing something like it on the open market. (ok,
maybe it's a bit Dick Tracey but I had to ask).
If you have any suggestions, please send them to me. I
figured with all these bright people someone would have run across
this sort of problem before and found a creative solution.
And please, no boat full of magtape replies... ;-) These folks use
PC's.

Interesting.
Actually, Dave wrote the thing and wrote the code and, etc., but i think i
actually agree with Steve's point of view.
If the application wants to be running in some mode "linemode" supports
(mostly, standard shell prompt mode), then linemode should be "operative".
But, as soon as the application wants to do something funny (like, run vi,
say), then the application will put the pty in something like "raw" mode,
and *that* should cause the telnet server to say "drop out of linemode for
a bit" to the client (until the application says "go back into "normal"
mode).
That's my base view of how linemode should be operating. It protects the
server side from traffic generated during "normal" TTY operations, but not
during "raw" TTY operations.
Then, Steve's point (to me) is that NO MATTER WHAT THE CLIENT says
(prompted by the user into saying it, or by some other trigger), linemode
should *NOT* be made operative by the server if the pty is in *RAW* mode
(set there by the application).
Dave, clearly you think i'm wrong. But, *i* think i'm write :). What say you?
> 2) The application on the master pty side has to be

Now, i'm not a pty expert, so i can't tell if "the application on the

is here (since i'm assuming you meant b, but *i* want a).

You can buy a VSAT with two 56Kbps channels for approx $25K. Hughes and
others
have the terminals or can tell you where to get them. I researched this
last
year for a project. We were going to hook-up some Cisco routers via
a VSAT link. We were going to have van that traveled all over North America
and since it moved a lot, dedicated 128Kbps was not practical. Project
got canceled but I had lots of data.
ATT told me they would lease a full-time 56Kbs non-vsat circuit to me for
$3K a month. I'm don't think that applies to Central America though
(See next set of comments below).

Oh yeah, the Magnavox MagnaPhone does work and is available. I don't
have any costing but would guess its about $15K-$25K. The problem here
is that it uses satellite service from INTELSAT or INMARSAT which have
very very high usage rates. I should note, this should also apply to VSAT
to Central America.
I think you will find out you can afford to ground station but you can
not afford the air-time charges for dial-up or fixed bandwidth full-time.
How I started was I began to read all networking magazines and rag sheets.
P.S. There will be VSAT vendors at InterOP next week. Last year there were
about 6 at the show and I got most of my information there.

Working Group of the IETF.
Title : SIPP Program Interfaces for BSD Systems
Author(s) : R. Gilligan, R. Govindan, S. Thomson, J. Bound
Filename : draft-ietf-sipp-bsd-api-02.txt
Pages : 12
Date : 04/28/1994
In order to implement the Simple Internet Protocol (SIPP) in an operating
system based on 4.x BSD, changes must be made to some of the application
program interfaces (APIs). TCP/IP applications written for BSD-based
operating systems have in the past enjoyed a high degree of portability
because most of the systems derived from BSD provide the same API, known
informally as "the socket interface". We would like the same portability
to be possible with SIPP applications. This memo presents a set of changes
to the BSD socket API to support SIPP. The changes include a new data
structure to carry SIPP address sequences, new name to address translation
library functions, new address conversion functions, and some new
setsockopt() options. The changes are designed to be minimal and to provide
source and binary compatibility for existing applications.

Title : Bombs series: Behaviour of Mail Based Servers
Part 1: C-bombs
Classification of Breeds of Mail Based Servers
Author(s) : J. Houttuin
Filename : draft-rare-msg-c-bombs-01.txt
Pages : 12
Date : 04/28/1994
This document defines a classification of Mail Based Servers (MBSs)
according to their behaviour towards their users. The most important
distinction is between mail responders (e.g. echo servers, file servers)
and mail forwarders (e.g. mailing lists, auto-forwarders). The document
aims at a common understanding of these MBS classes and other common MBS
attributes, such as roles (administrators, owners), MBS lifetime and
restricted MBS use.
