The IESG has approved the following document: - 'A Session Initiation Protocol (SIP) Usage for Incremental Provisioning of Candidates for the Interactive Connectivity Establishment (Trickle ICE)' (draft-ietf-mmusic-trickle-ice-sip-18.txt) as Proposed Standard This document is the product of the Multiparty Multimedia Session Control Working Group. The IESG contact persons are Adam Roach, Alexey Melnikov and Ben Campbell. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-mmusic-trickle-ice-sip/ 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.
