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). The document also defines a new
SIP Info Package to support this usage together with the
corresponding media type. Additionally, a new Session Description
Protocol (SDP) "end-of-candidates" attribute and a new SIP option tag
"trickle-ice" are defined.
This document is a product of the Multiparty Multimedia Session Control Working
Group of the IETF.
This is now a Proposed Standard.
