I have reviewed this document as part of the security directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written primarily for the benefit of the security area directors. Document editors and WG chairs should treat these comments just like any other last call comments. The summary of the review is Ready. This document extends the existing ICE mechanism to allow the ICE agent to wait a bit longer to allow for the discovery of candidates by adding new timer to the ICE agent. The new timer does not change the existing operation of the ICE mechanism and has no security implications.
