Description
NFD EthernetFace multicasts all packets.
In a large scale L2 network with non-NDN-aware switches, multicasting would wake up all nodes, which is not energy efficient.
Therefore, we should design a L3-L2 binding machinery.
Dave Oran provided some ideas:
- use different multicast addresses for Interests and Data
- partition the multicast space using prefix hashes
- decide whether to unicast or multicast a Data packet, based on how many downstreams have requested it
- use routing to suppress redundant forwarding of interests received by multiple forwarders on the same LAN
