Shepherd writeup

1. Summary

The document shepherd is Ari Keränen. The responsible Area Director is Ben

This document provides guidelines on how to make Interactive Connectivity
Establishment (ICE) conclude faster in multihomed and IPv4/IPv6 dual-stack
scenarios where broken paths exist. The provided guidelines are backwards
compatible with the original ICE specification.

2. Review and Consensus

The document has been worked both at MMUSIC and ICE working groups since IETF
#86 and the document has received multiple reviews over time. Overall the
mechanism is simple but details of the suggested algorithm were discussed and
updated throughout the process. General concerns on behaviour with unreliable
tunnelling mechanisms were raised but no specific issues were discovered and
the draft was updated to note this issue in general. The final version received
four reviews. Reviews from WGLC resulted only in editorial changes. There are
two implementations of the mechanism.

3. Intellectual Property

Each author has confirmed conformance with BCP 78/79. There are no IPR
disclosures on the document.

4. Other Points

While the document uses RFC2119 text to describe the mechanism, there was WG
consensus to publish this as Informational document. The reference to obsoleted
RFC 3484 is intentional as it is part of the discussion of evolution of
prioritisation rules.
