Description of Working Group:

The goal of the IP1394 Working Group is to define how the Internet Protocol (IPv4 & IPv6) is supported over IEEE 1394 Serial Bus. IEEE 1394 Serial Bus (1394) is specified by IEEE Std 1394-1995 and the draft standard IEEE P1394a. The IP1394 working group intends for the specification to be utilized by devices with a broad range of capabilities. These devices are expected to include (but not be limited to) both traditional equipment such as computers, as well as equipment that has not traditionally been networked, such as consumer electronics (e.g. TVs & VCRs).

Unlike most other data link protocols, IEEE 1394 provides the capability for isochronous as well as asynchronous transmission. This capability can have a significant impact on how IP is supported on 1394. The IP1394 working group will prepare an architecture document and appropriate protocol documents for the usage of these unique link layer properties. Both IPv4 and IPv6 will be addressed, although in separate documents.

The IP1394 working group is chartered to deliver the documents described below. The working group will maintain informal liaison with other standards groups and industry organizations doing related work. Some of these documents may depend upon facilities not currently standardized in 1394. If necessary, working group members will work within the IEEE standards process to request modification or extension of existing IEEE standards (or standards in development).

The deliverable documents are as follows:

- An architecture document detailing the interactions between 1394 asynchronous and isochronous transmissions, resource reservation and multicast.

- An IPv4 over 1394 document covering the encapsulation and framing of IPv4 unicast, multicast and broadcast packets over asynchronous and isochronous 1394, including address resolution.

- An IPv6 over 1394 document covering the encapsulation and framing of IPv6 unicast, multicast and broadcast packets over asynchronous and isochronous 1394, including neighbor discovery.

- A media-specific MIB for managing 1394 interfaces.

Current Meeting Report

Myron & Tony
WG Co-Chairs

About 40 people attended our single IP/1394 session.

The agenda for themeeting was:

- Submit draft to IESG for Proposed Standard 5 minutes
(Postponed until successful WG last call)
- Why we are postponing work on IPv6 5 minutes
- Why we are postponing work on IP over 1394 isoch streams 5 minutes
- Request volunteers to work on SNMP MIB proposal 10 minutes
- DHCP 30-60 minutes

The meeting followed the agenda with an additional item of explaining the detailed
process of moving the draft to Proposed Standard. To summarize, after a successful
Working Group Last Call, the WG submits the draft to IESG, the IESG will do an
IETF Last Call. Once the IETF Last Call is successful, the draft is assigned an RFC
number to become a Proposed Standard.

No one objected to our postponement of work on Ipv6 and Ip over isoc 1394. The
request for volunteers to work on SNMP MIB met silence. The people that had
previously expressed interest in working on a MIB were not in attendance.

As indicated by the agenda, the bulk of the meeting was spent discussing extensions
to DHCP. The Sony draft defines values for the Client Hardware Address (chaddr) and
Client Identifier DHCP options. The only technical change for a new EUI-64 Hardware
Type requires a number to be allocated by IANA. Editorial additions will explain how
to use the 1394 chaddr and client identifier values in different scenarios such as dynamic
address allocation. Sony agreed to be the editor of the DHCP extensions WG draft. Once
complete, the "DHCP Extensions for IP/1394" draft will be submitted for review by the
DHCP WG with the intention of our WG producing an informational RFC.


None received.
