Technical Summary
This document updates the definition of Traversal Using Relays around NAT
(TURN), RFC5766, a protocol that allows the host to control the operation of
the relay and to exchange packets with its peers using the relay. The
updates improve protocol support for IPv6 and DTLS, adds support for
receiving ICMP packets, and updates PMTUD. The new revision also improves
document clarity regarding tunnel amplification attacks and packet
translation.
Working Group Summary
This document represents one of the core milestones for the TRAM working
group and as such has undergone significant discussion, review, and
revision. There has been no significant controversy of note in the updates
to this document. This document's dependence upon some other documents, most
notably updates to Session Traversal Utilities for NAT (STUN)
I-D.ietf-tram-stunbis, have led to delay in this document's completion, but
have not increased the difficulty of coming to consensus on this document's
contents.
Document Quality
This draft has continuously been reviewed by many different people
throughout its history. The most significant updates have been the subject
of discussion in TRAM WG meetings throughout the documents lifetime.
Comprehensive reviews of the full set of updates have been done by two
active WG members. This review includes coverage for consistency with the
related stunbis document. All of the review feedback has been addressed by
the authors.
