Question about Endpoint ip_address #35

Closed garethsb closed 4 years ago

garethsb commented 5 years ago

I understand an Endpoint (a network interface) is uniquely identified by its chassis_id and port_id (as well as separately by the BC-assigned id).

The Endpoint schema has ip_address as a required property which is a single IPv4 or IPv6 address.

Should an Endpoint always have one IP address? Or is it possible an Endpoint could have multiple associated IP addresses (e.g. virtualization cases)? Or currently have no assigned IP addresses?

Multiple endpoints can share same chassis_id and port_id. Endpoint schema description indicates that chassis ID can be null when not available. If there are multiple IP addresses associated w/ single physical device (endpoint) then it would be modeled as multiple virtual endpoints each w/ unique IP addresses ..Sachin

Thanks, Sachin. OK, I now understand one network interface could have be registered into IS-06 Network Controller as several Endpoints with same chassis_id (which may be null) and port_id (MAC address).

Therefore in order to register an Endpoint, the Broadcast Controller needs to combine properties from the IS-04 Node (interfaces, which one identified via the Sender or Receiver interface_bindings) with properties from the IS-05 Sender or Receiver active transport_params (source_ip or interface_ip).
