A new Request for Comments is now available in online RFC libraries. RFC 8083 Title: Multimedia Congestion Control: Circuit Breakers for Unicast RTP Sessions Author: C. Perkins, V. Singh Status: Standards Track Stream: IETF Date: March 2017 Mailbox: csp@csperkins.org, varun@callstats.io Pages: 25 Characters: 67197 Updates: RFC 3550 I-D Tag: draft-ietf-avtcore-rtp-circuit-breakers-18.txt URL: https://www.rfc-editor.org/info/rfc8083 DOI: 10.17487/RFC8083 The Real-time Transport Protocol (RTP) is widely used in telephony, video conferencing, and telepresence applications. Such applications are often run on best-effort UDP/IP networks. If congestion control is not implemented in these applications, then network congestion can lead to uncontrolled packet loss and a resulting deterioration of the user's multimedia experience. The congestion control algorithm acts as a safety measure by stopping RTP flows from using excessive resources and protecting the network from overload. At the time of this writing, however, while there are several proprietary solutions, there is no standard algorithm for congestion control of interactive RTP flows. This document does not propose a congestion control algorithm. It instead defines a minimal set of RTP circuit breakers: conditions under which an RTP sender needs to stop transmitting media data to protect the network from excessive congestion. It is expected that, in the absence of long-lived excessive congestion, RTP applications running on best-effort IP networks will be able to operate without triggering these circuit breakers. To avoid triggering the RTP circuit breaker, any Standards Track congestion control algorithms defined for RTP will need to operate within the envelope set by these RTP circuit breaker algorithms. This document is a product of the Audio/Video Transport Core Maintenance Working Group of the IETF. This is now a Proposed Standard. STANDARDS TRACK: This document specifies an Internet Standards Track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the Official Internet Protocol Standards (https://www.rfc-editor.org/standards) for the standardization state and status of this protocol.
