Abstract

This document specifies ROHC (Robust Header Compression) profilesthat efficiently compress RTP/UDP/IP (Real-Time Transport Protocol,User Datagram Protocol, Internet Protocol), RTP/UDP-Lite/IP (UserDatagram Protocol Lite), UDP/IP, UDP-Lite/IP, IP and ESP/IP(Encapsulating Security Payload) headers.

This specification defines a second version of the profiles found inRFC 3095, RFC 3843 and RFC 4019; it supersedes their definition, butdoes not obsolete them.

The ROHCv2 profiles introduce a number of simplifications to therules and algorithms that govern the behavior of the compressionendpoints. It also defines robustness mechanisms that may be used bya compressor implementation to increase the probability ofdecompression success when packets can be lost and/or reordered onthe ROHC channel. Finally, the ROHCv2 profiles define their ownspecific set of header formats, using the ROHC formal notation. [STANDARDS-TRACK]
