Table 1. RoHC Requirements
Performance Must provide low relative overhead under expected operating conditions.
IPv6 or IPv4 Must include support for both IPv6 and IPv4.
Ubiquity Must not require modifications to existing IP, UDP or RTP stack.
Cellular Handoff Must be supported in an efficient manner. All fields must be made transparent to the process.
Integrity The compression/decompression must be loss-less.
Error Propagation Error propagation due to header compression should be kept to an absolute minimum or avoided.
Delay Header compression process must not contribute significantly to the system delay budget.
Packet Loss The preference is that the header compression algorithm is as independent as possible to packet loss rate.
Media supported Must function regardless of media type in RTP payload. In general, there is no required knowledge of payload.
Call Type Independence Must function for mobile-to-mobile and mobile-to-POTS calls.
