Technical Summary

The Interactive Connectivity Establishment (ICE) protocol describes a Network Address Translator (NAT) traversal mechanism for UDP-based multimedia sessions established with the Offer/Answer model.  The ICE extension for Incremental Provisioning of Candidates (Trickle ICE) defines a mechanism that allows ICE Agents to shorten session establishment delays by making the candidate gathering and connectivity checking phases of ICE non-blocking and by executing them in parallel.

This document defines usage semantics for Trickle ICE with the Session Initiation Protocol (SIP) and defines a new Info Package as specified in [RFC6086].


Working Group Summary

The document has been a WG document since 2014, where it saw significant interest in the WG. The document has since then undergone several changes as a result of WG feedback, however none of those have been controversial. 


Document Quality

We have not received information about current implementations, however the document is a companion document to draft-ietf-ice-trickle, which is a normative dependency for the W3C WebRTC specification.
