For dual stack hosts, ICE will prefer IPv6 addresses over IPv4 as per RFC6724 and connectivity checks have to be performed on all IPv6 candidates before trying IPv4 candidates. If the IPv6 path is broken or is excessively slow, fallback to IPv4 candidates will be significantly slow and introduce user-visible delay. This draft proposes an algorithm that makes ICE connectivity checks more responsive to failures of an address family by performing connectivity checks with both IPv4 and IPv6 in parallel if IPv6 connectivity checks don't seem to succeed. Considering the fact that there is a very realistic chance that connectivity checks for relayed candidates will always work, the draft also proposes an optimization such that connectivity checks with relayed candidates are performed earlier than usual if connectivity checks using other candidates do not succeed quickly. Comments and feedback welcome. -Prashanth On 04/10/12 8:06 AM, "internet-drafts@ietf.org" <internet-drafts@ietf.org> wrote: > >A new version of I-D, draft-reddy-mmusic-ice-happy-eyeballs-00.txt >has been successfully submitted by Tirumaleswar Reddy and posted to the >IETF repository. > >Filename: draft-reddy-mmusic-ice-happy-eyeballs >Revision: 00 >Title: Happy Eyeballs Extension for ICE >Creation date: 2012-10-04 >WG ID: Individual Submission >Number of pages: 10 >URL: >http://www.ietf.org/internet-drafts/draft-reddy-mmusic-ice-happy-eyeballs- >00.txt >Status: >http://datatracker.ietf.org/doc/draft-reddy-mmusic-ice-happy-eyeballs >Htmlized: >http://tools.ietf.org/html/draft-reddy-mmusic-ice-happy-eyeballs-00 > > >Abstract: > This document specifies requirements for algorithms that make ICE > connectivity checks more aggressive to reduce delays in dual stack > host connectivity checks when there is a path failure for the address > family preferred by the application or by the operating system.
