Technical Summary
This document specifies the usage of Datagram Transport Layer Security (DTLS)
as a transport protocol for Session Traversal Utilities for NAT (STUN). It
also specifies modifications to the STUN URIs and TURN URIs and to the TURN
resolution mechanism to facilitate the resolution of STUN URIs and TURN URIs
into the IP address and port of STUN and TURN servers supporting DTLS as a
transport protocol.
Working Group Summary
This is the first document produced by the TRAM working group. No controversy
was experienced. Many different people have provided feedback and guidance.
Some of the harder questions:
- What cipher suite to specify as mandatory?
- How to ensure that a hostname is available for certificate validation?
Document Quality
Two existing implementations are listed in section 5. RTCWEB implementers have
demonstrated interest.
This draft has continuously been reviewed by many different people throughout
its history. While the TRAM WG is composed primarily of NAT traversal
experts, TLS experts have been solicited and have provided very helpful
feedback, particularly at the IETF 89 meeting.
