sip - CSRC and SSRC in RTP - Stack Overflow
SSRC Identifies the synchronization source. The value is chosen randomly, with the intent that no two synchronization sources within the same RTP session will have the same SSRC. Although the probability of multiple sources choosing the same identifier is low, all RTP implementations must be prepared to detect and resolve collisions.
Is SSRC=0 in RTP packet header valid? - Stack Overflow
The SSRC identifier carried in the RTP header and in various fields of RTCP packets is a random 32-bit number that is required to be globally unique within an RTP session. It is crucial that the number be chosen with care in order that participants on the same network or starting at the same time are not likely to choose the same number.
RTP: SSRC collision detection in unicast sessions
2014年1月7日 · The distinguishing feature of an RTP session is that each maintains a full, separate space of SSRC identifiers. And: The set of participants included in one RTP session consists of those that can receive an SSRC identifier transmitted by any one of the participants either in RTP as the SSRC or a CSRC (also defined below) or in RTCP.
sockets - RTP packet identification - Stack Overflow
2014年5月4日 · Synchronization source (SSRC): The source of a stream of RTP packets, identified by a 32-bit numeric SSRC identifier carried in the RTP header so as not to be dependent upon the network address. All packets from a synchronization source form part of the same timing and sequence number space, so a receiver groups packets by synchronization ...

2015年6月18日 · The SSRC identifier is a randomly chosen value meant to be globally unique within a particular RTP session (see Section 8). A participant need not use the same SSRC identifier for all the RTP sessions in a multimedia session; the binding of the SSRC identifiers is provided through RTCP (see Section 6.5.1).
WebRTC: Relationship between Channels, Tracks & Streams vis-a …
2018年12月7日 · Several recent RFCs (E.g. 8108) refer to the need to have multiple streams sent in one RTP session. Each stream is to have its own SSRC at the RTP level. In the RFC for Unified Plan too, the reference is always to a stream as the lowest level (not tracks or channels). In RFC 3550, the base RTP RFC, there is no reference to channel.
