Internet Engineering Task Force (IETF) A. Niemi Request for Comments: 6446 K. Kiss Updates: 3265 Nokia Category: Standards Track S. Loreto ISSN: 2070-1721 Ericsson January 2012 Session Initiation Protocol (SIP) Event Notification Extension for Notification Rate Control Abstract This document specifies mechanisms for adjusting the rate of Session Initiation Protocol (SIP) event notifications. These mechanisms can be applied in subscriptions to all SIP event packages. This document updates RFC 3265. Status of This Memo This is an Internet Standards Track document. This document is a product of the Internet Engineering Task Force (IETF). It represents the consensus of the IETF community. It has received public review and has been approved for publication by the Internet Engineering Steering Group (IESG). Further information on Internet Standards is available in Section 2 of RFC 5741.
