The Stream Control Transmission Protocol as a Transport for the Session Initiation Protocol
RFC 4168, “The Stream Control Transmission Protocol as a Transport for the Session Initiation Protocol”, is a Proposed Standard document published in October 2005 by J. Rosenberg, H. Schulzrinne, G. Camarillo. It has since been updated by RFC 8996. The canonical text is published by the RFC Editor.
Abstract
This document specifies a mechanism for usage of SCTP (the Stream Control Transmission Protocol) as the transport mechanism between SIP (Session Initiation Protocol) entities. SCTP is a new protocol that provides several features that may prove beneficial for transport between SIP entities that exchange a large amount of messages, including gateways and proxies. As SIP is transport-independent, support of SCTP is a relatively straightforward process, nearly identical to support for TCP. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
