Hi,

After asking for review of draft-ietf-mmusic-ice-dualstack-fairness by an IPv6 guy (not on the MMUSIC list) he pointed out that he was a bit confused regarding the term multihomed agent. Apparently there are several variations of multihoming; multi-interface multihoming, multi-prefixing multihoming, site multihoming and so on.

Not sure if this is confusing or needs a better definition in the various ICE specs. Any thoughts?

The current and slightly updated text in the fainess drafts says:

A multihomed ICE agent can potentially send and receive connectivity
checks on all available interfaces and IP addresses.  It is possible
for an interface to have several IP addresses associated with it.  To
avoid unnecessary delay when performing connectivity checks it would
be beneficial to prioritize interfaces and IP addresses known by the
agent to provide stable connectivity.  If the agent have access to
information about the physical network it is connected to (Like SSID
in a WiFi Network) this can be used as information regarding how that
network interface should be prioritized at this point in time.

Does the text above need a stricter multihomed definition?
