IS-04 Sender "interface_bindings" for IS-07 Senders

[garethsb]

This may be more of a question for IS-04.

The example in Core models - IS-04 highlights - Senders shows "interface_bindings": [ "eth0" ].

Does it make sense for Senders with transports like WebSocket or MQTT to be bound to a particular interface?

If so, in an out-of-band configuration (separate media and control networks) which network would WebSocket/MQTT flows be likely to use?

I think that strictly speaking we would have to announce the out-of-band interfaces and bind to them in order not to violate the existing NMOS. I can also see how that leads to increased complexity and potential confusion, so in my opinion it is a very valid discussion topic.

This is now an issue in IS-05 - AMWA-TV/is-05#70 - since binding to multiple interfaces in IS-04 probably then requires that we represent the multiple redundant interfaces with multiple 'legs' in IS-05.
