>> The Resource ReserVation Protocol (RSVP) defines an ERROR_SPEC object

>> ERROR_SPEC to carry additional user information related to errors.

Hi Ash,

yes, that is a (at least by me) known issue... This comes up, when you
dimension your parameters to fullfil a given path error detection  
time...

I'm not sure if we should start again an errata ID...

Best regards
Michael

Could anyone please tell me, how to register a socket to get neighbour
table update call back.

For example, one can get route table update, by creating a netlink
socket and registering it in "nl_groups" and then setting function
pointer "sk_data_ready" from sk.
This invoks the function pointer by "sk_data_ready" whenever route
table is modified.

Could somebody please tell the procedure to get the neighbour table callbacks .

Regards,
Bharati.

This is a wrong mailing list for this question.  It sounds like you are
using linux and should direct these questions to linux-net@vger.kernel.org
or netdev@vger.kernel.org

Ash,

Yes, I agree.

This looks worth submitting to the RFC Editor as an
Errata to RFC 4960.

Hi Lars,

I have submitted an errata. The correct text should say in section 8.3:

    When the value of this counter exceeds the protocol parameter
    'Path.Max.Retrans', the endpoint should mark the corresponding
    destination address as inactive if it is not so marked, and may also
    optionally report to the upper layer the change of reachability of
    this destination address.

Best regards
Michael

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Transport Area Working Group Working Group of the IETF.


	Title           : Guidelines for Application Designers on Using Unicast UDP
	Author(s)       : L. Eggert, G. Fairhurst
	Filename        : draft-ietf-tsvwg-udp-guidelines-08.txt
	Pages           : 27
	Date            : 2008-06-13

The User Datagram Protocol (UDP) provides a minimal, message-passing
transport that has no inherent congestion control mechanisms.
Because congestion control is critical to the stable operation of the
Internet, applications and upper-layer protocols that choose to use
UDP as an Internet transport must employ mechanisms to prevent
congestion collapse and establish some degree of fairness with
concurrent traffic.  This document provides guidelines on the use of
UDP for the designers of unicast applications and upper-layer
protocols.  Congestion control guidelines are a primary focus, but
the document also provides guidance on other topics, including
message sizes, reliability, checksums and middlebox traversal.

TSVWG

This is a reminder of the cut-off dates for draft submission for IETF-72:

- Monday, July 7th for -00s by 17:00 PDT (24:00 UTC/GMT)

- Monday, July 14th for -01+ by 17:00 PDT (24:00 UTC/GMT)


**NOTICE THE *DEADLINE* TIME CHANGE FOR SUBMISSIONS**


Yes, that's right, we have 13 additional hours (each deadline) to 
work on submissions
    (oh, the possibilities...!)

Refer here for complete details:
http://www.ietf.org/meetings/72/72-cutoff_dates.html

So, these dates are just a few weeks off and our WG agenda is due on 
July 16th (less than a month away).

Also, please use the tool to upload your document:

https://datatracker.ietf.org/idst/upload.cgi

It will be published very, very quickly this way, but I will note 
that it does not check for ALL the nits, so it's a good idea to run 
idnits before submitting:

http://tools.ietf.org/tools/idnits/

Also, please send me a note if you want agenda time to present an ID. 
I, again, will be building the agenda for TSVWG, and I'm not that 
good at reading people's minds to know that they meant to submit a 
request.  Once the agenda time is used up, it is used up.  Agenda 
time preference will be given to TSVWG items.

Don't surprise me with a request for agenda time on July 28th, given 
that official agendas are due on the 16th.


Cheers,
James
IETF TSVWG co-chair
