Description
The current self-learning forwarding strategy implementation will broadcasts a discovery Interest to all non-local Faces, except the one (not ad hoc) that Interest was sent in. However, in the default configuration, three multicast faces will be created on the same physical link, Ethernet, UDP4, and UDP6 faces. To avoid sending duplicate packets to the same physical links, self-learning should be able to identify which Faces are connected to the same NIC. How to choose one multicast face? One option is to follow this order: Ethernet > UDP4 > UDP6. To summarize: there are two tasks:
- adding physical interface name to Face
- choose one multicast Face on one physical interface to broadcast a discovery Interest in self-learning
