RObust Header Compression (ROHC):Profiles for UDP Lite
Ericsson AB
This document defines ROHC (Robust Header Compression) profiles for compression of RTP/UDP-Lite/IP packets (Real-Time Transport Protocol, User Datagram Protocol Lite, Internet Protocol) and UDP-Lite/IP. These profiles are defined based on their differences with the profiles specified in [RFC-3095] for UDP [RFC-768]. Although both transport protocols are very similar, ROHC profiles must be defined separately for robust compression of UDP-Lite headers because it does not share protocol identifier with UDP. Also, the UDP-Lite Checksum Coverage field does not share the semantics of the corresponding UDP Length field and as a consequence cannot always be inferred anymore.
