I think if you go back and review the "Gathering Candidates" section of http://tools.ietf.org/html/draft-ietf-mmusic-ice-19, you'll see that the Host Candidate portion covers this area: The first step is to gather host candidates. Host candidates are obtained by binding to ports (typically ephemeral) on a IP address attached to an interface (physical or virtual, including VPN interfaces) on the host. Those candidates become part of the overall candidate list (and it gets much, much more complicated than this small snippet would indicate), and the SDP exchange is then a signalling-path mechanism for working out the best flow pairing. regards, Ted _______________________________________________ Ietf mailing list Ietf@ietf.org https://www.ietf.org/mailman/listinfo/ietf
