The IESG has approved the following document: - 'Signalling Connection Control Part User Adaptation Layer (SUA) ' <draft-ietf-sigtran-sua-16.txt> as a Proposed Standard This document is the product of the Signaling Transport Working Group. The IESG contact persons are Jon Peterson and Allison Mankin. Technical Summary This memo defines a protocol for the transport of a number of telephony signaling protocols. Specifically it supports the transport of any Signaling Connection Control Part-User (SCCP-User) signaling protocols (e.g., Transaction Capabilities Protocol, Radio Access Network Application Protocol, etc.) over IP using the Stream Control Transport Protocol (SCTP) The protocol is modular and symmetric, to allow it to work in diverse architectures, such as a Signaling Gateway to IP Signaling Endpoint architecture as well as a peer-to-peer IP Signaling Endpoint architecture. Protocol elements have been included to allow operation between peers in the Signaling System-7 (SS7) and IP domains. Working Group Summary The working group supported the publication of this document and no issues were raised during IETF Last-Call. Protocol Quality This document was reviewed for the IESG by Scott Bradner.
