RE: [rohc] FW: I-D ACTION:draft-pelletier-rohc-udplite-01.txt

["Price, Richard" <richard.price@roke.co.uk>]

Hi,

The updated draft is quite a bit longer than the old one - a list of
what's changed since the previous version would be much appreciated!

One point I noticed is that the new draft supports the compression
of multiple IP headers. Is this something that's particularly useful
for UDP-Lite (as compared with vanilla UDP), or just a feature that
would be good to have in general?

Thanks,

Richard

To remove yourself from the IETF Announcement list, send a message to 
ietf-announce-request with the word unsubscribe in the body of the message.

Internet-Drafts are also available by anonymous FTP. Login with the username
"anonymous" and a password of your e-mail address. After logging in,
type "cd internet-drafts" and then
	"get draft-pelletier-rohc-udplite-01.txt".

A list of Internet-Drafts directories can be found in
http://www.ietf.org/shadow.html 
or ftp://ftp.ietf.org/ietf/1shadow-sites.txt


Internet-Drafts can also be obtained by e-mail.

Send a message to:
	mailserv@ietf.org.
In the body type:
	"FILE /internet-drafts/draft-pelletier-rohc-udplite-01.txt".
	
NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.
