Abstract
This document defines a protocol for the transport of any Signalling
Connection Control Part-User signalling over IP using the Stream
Control Transmission Protocol. The protocol is designed to be
modular and symmetric, to allow it to work in diverse architectures,
such as a Signalling Gateway to IP Signalling Endpoint architecture
as well as a peer-to-peer IP Signalling Endpoint architecture.
