Datagram Transport Layer Security Encapsulation of SCTP Packets
RFC 8261, “Datagram Transport Layer Security Encapsulation of SCTP Packets”, is a Proposed Standard document published in November 2017 by M. Tuexen, R. Stewart, R. Jesup, S. Loreto. It has since been updated by RFC 8899, RFC 8996. The canonical text is published by the RFC Editor.
Abstract
The Stream Control Transmission Protocol (SCTP) is a transport protocol originally defined to run on top of the network protocols IPv4 or IPv6. This document specifies how SCTP can be used on top of the Datagram Transport Layer Security (DTLS) protocol. Using the encapsulation method described in this document, SCTP is unaware of the protocols being used below DTLS; hence, explicit IP addresses cannot be used in the SCTP control chunks. As a consequence, the SCTP associations carried over DTLS can only be single-homed.
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.
