A new Request for Comments is now available in online RFC libraries. RFC 8108 Title: Sending Multiple RTP Streams in a Single RTP Session Author: J. Lennox, M. Westerlund, Q. Wu, C. Perkins Status: Standards Track Stream: IETF Date: March 2017 Mailbox: jonathan@vidyo.com, magnus.westerlund@ericsson.com, bill.wu@huawei.com, csp@csperkins.org Pages: 29 Characters: 74580 Updates: RFC 3550, RFC 4585 I-D Tag: draft-ietf-avtcore-rtp-multi-stream-11.txt URL: https://www.rfc-editor.org/info/rfc8108 DOI: 10.17487/RFC8108 This memo expands and clarifies the behavior of Real-time Transport Protocol (RTP) endpoints that use multiple synchronization sources (SSRCs). This occurs, for example, when an endpoint sends multiple RTP streams in a single RTP session. This memo updates RFC 3550 with regard to handling multiple SSRCs per endpoint in RTP sessions, with a particular focus on RTP Control Protocol (RTCP) behavior. It also updates RFC 4585 to change and clarify the calculation of the timeout of SSRCs and the inclusion of feedback messages. 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.
