The IESG has approved the following document: - 'Trickle ICE: Incremental Provisioning of Candidates for the Interactive Connectivity Establishment (ICE) Protocol' (draft-ietf-ice-trickle-21.txt) as Proposed Standard This document is the product of the Interactive Connectivity Establishment 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-ice-trickle/ Technical Summary This document describes "Trickle ICE", an extension to the Interactive Connectivity Establishment (ICE) protocol that enables ICE agents to send and receive candidates incrementally rather than exchanging complete lists. With such incremental provisioning, ICE agents can begin connectivity checks while they are still gathering candidates and considerably shorten the time necessary for ICE processing to complete. Working Group Summary Though the number of reviews during Working Group Last Call was low, the document received quite a few reviews over its lifetime. Document Quality The extension is reasonably easy to add to an existing ICE implementation. Several independent implementations are deployed and are interoperable. No formal reviews are needed. The shepherd has no remaining concerns. Personnel The document shepherd is Nils Ohlmeier. The responsible Area Director is Ben Campbell.
