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.

STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the Official
Internet Protocol Standards ( for the
