The IESG has approved the following document: - 'Latching: Hosted NAT Traversal (HNT) for Media in Real-Time Communication' (draft-ietf-mmusic-latching-08.txt) as Informational RFC This document is the product of the Multiparty Multimedia Session Control Working Group. The IESG contact persons are Alissa Cooper and Richard Barnes. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-mmusic-latching/ Technical Summary This document describes behavior of signalling intermediaries in Real-Time Communication (RTC) deployments, sometimes referred to as Session Border Controllers (SBCs), when performing Hosted NAT Traversal (HNT). HNT is a set of mechanisms, such as media relaying and latching, that such intermediaries use to enable other RTC devices behind NATs to communicate with each other. Working Group Summary There is WG consensus behind this draft. All issues raised during and before WGLC have been addressed. There were concerns regarding the harmfulness of the documented mechanisms, especially regarding security. The document was updated to stress that it only documents existing behavior and does not recommend them as good practices. Document Quality The document is well written and readable. It documents existing behavior that has been already earlier implemented by various vendors. Personnel Ari Keranen is the Document Shepherd, and the Responsible Area Director is Alissa Cooper.
