…the Real-time Transport Protocol has SSRC collisions, which although very rare [RFC3550] are quite possible. During a collision, two or more SSRCs that share a master key will have identical keystreams for overlapping portions of the RTP sequence number space. SRTP Security Descr…

…ot self-delimiting. Instead, it assumes that a lower layer (such as UDP or RTP [RFC3550] or Ogg [RFC3533] or Matroska [MATROSKA-WEBSITE]) will communicate the length, in bytes, of the packet, and it uses this information to reduce the framing overhead in the packet itself. A deco…

…C 5285 RTP Header Extensions July 2008 1 . Introduction The RTP specification [ RFC3550 ] provides a capability to extend the RTP header. It defines the header extension format and rules for its use in Section 5.3.1 . The existing header extension method permits at most one exten…

As described in [ RFC3550 ] , RTP packets are associated with RTP streams [ RFC7656 ] . Each RTP stream is identified by an SSRC value, and each RTP packet includes an SSRC field that is used to associate the packet with the correct RTP stream. RTCP packets also use SSRCs to iden…
