From: The IESG <firstname.lastname@example.org> To: IETF-Announce <email@example.com> Cc: Internet Architecture Board <firstname.lastname@example.org>, RFC Editor <email@example.com>, simple mailing list <firstname.lastname@example.org>, simple chair <email@example.com> Subject: Document Action: 'Presence Interdomain Scaling Analysis for SIP/SIMPLE' to Informational RFC The IESG has approved the following document: - 'Presence Interdomain Scaling Analysis for SIP/SIMPLE ' <draft-ietf-simple-interdomain-scaling-analysis-06.txt> as an Informational RFC This document is the product of the SIP for Instant Messaging and Presence Leveraging Extensions Working Group. The IESG contact persons are Robert Sparks and Cullen Jennings. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-simple-interdomain-scaling-analysis-06.txt
Technical Summary The document analyzes the traffic that is generated due to presence subscriptions between domains. It is shown that the amount of traffic can be extremely big. In addition to the very large traffic the document also analyzes the affects of a large presence system on the memory footprint and the CPU load. Current approved and in work optimizations to the SIP protocol are analyzed with the possible impact on the load. Separate documents contain the requirements for optimizations and suggestions for new optimizations. Working Group Summary This document received input from many contributors and was extensively reviewed both in and outside the SIMPLE working group. Personnel Ben Campbell is this document's shepherd. Robert Sparks is the responsible Area Director.
