This document specifies ROHC (Robust Header Compression) profiles thatefficiently compress RTP/UDP/IP (Real-Time Transport Protocol, UserDatagram Protocol, Internet Protocol), RTP/UDP-Lite/IP (User DatagramProtocol Lite), UDP/IP, UDP-Lite/IP, IP and ESP/IP (EncapsulatingSecurity Payload) headers. This specification defines a secondversion of the profiles found in RFC 3095, RFC 3843 and RFC 4019; itsupersedes their definition, but does not obsolete them. The ROHCv2profiles introduce a number of simplifications to the rules andalgorithms that govern the behavior of the compression endpoints. Italso defines robustness mechanisms that may be used by a compressorimplementation to increase the probability of decompression successwhen packets can be lost and/or reordered on the ROHC channel.Finally, the ROHCv2 profiles define its own specific set of packetformats, using the ROHC formal notation.
