Abstract

This document defines Robust Header Compression (ROHC) profiles for compression of Real-Time Transport Protocol, User Datagram Protocol- Lite, and Internet Protocol (RTP/UDP-Lite/IP) packets and UDP- Lite/IP. These profiles are defined based on their differences with the profiles for UDP as specified in RFC 3095.
