Chapter 23. Signalling Compression

Signalling Compression (SigComp) is a mechanism that application protocols use to compress messages before sending them across the network. It is presented to applications as a layer between application protocols and transport protocols. SigComp uses a Universal Decompressor Virtual Machine (UDVM) to decompress messages. Figure 8.1 demonstrates SigComp's location in the protocol stack. SigComp is defined in [RFC3320].

A message that is compressed using SigComp is referred to as a SigComp message.
