[Nfd-dev] NDN-RTC poke Data to CS

[Alex Afanasyev]

Hi Jeff,

Even in the first release, there is no problem with unsolicited data caching for **local** faces (unix socket and tcp connection to localhost address), which should be sufficient for any stand-alone application, including ndnrtc.

I'm kind of blanking right now on how ndnrtc relates to browser (is it inside browser and can do local connection or javascript will to websockets for that).  If it is websocket, then the websocket "proxy" (and/or special face inside NFD---just in case, this will not be in the first release) can be made "local", so unsolicited caching can be enabled.

In any case, as Beichuan pointed out, Junxiao described the behavior that will be in the first release, which will have exactly one hard-coded caching policy for the content stored.  Next releases would have policies that can be adjusted per node.
