Ballot Text

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.


  Ari Keranen is the Document Shepherd, and the Responsible Area
  Director is Alissa Cooper.
