[Ndn-interest] ChronoChat and its default RIB entries

[Alex Afanasyev]

Hi Anil,

I think you’re mixing a couple of things.  The face that ChronoChat application uses is just a channel between the application and NFD.  It is normally unix socket face, but it doesn’t really matter, as it is not related to you being able to chat with other people.

Besides having a face that points to a remote chat node, you need to instruct NFD (RIB manager specifically) that specific data can be reached through this face.

In your specific face, you may start by registering /ndn/broadcast prefix for your multicast udp face:

    nfdc register /ndn/broadcast 294

This will tell NFD that data packets with prefix /ndn/broadcast can be retrieved if interest send out through face 294.   You can also register / prefix, which will essentially mean that NFD can try this face to fetch all kind of data packets.
