"forwarding-pipelines_20140129.pptx" is design update after 20140129 conference call.

Remaining problems:

  • incoming Interest pipeline, CS match branch: if an Interest from face 1 matches Data packet A at CS, A should go to face 1. At this time, ccnd would look up PIT to find other Interests pending on face 1 that could be satisfied by A, and consume these Interests. When will this ever happen?
  • incoming Interest pipeline, CS match branch: InRecord should be deleted
  • incoming Data pipeline: an incoming Data packet is forwarded to each pending downstream at most once. Is there any other scenario that can cause the same Data packet going into the same face twice? If so, deduplication is needed in outgoing Data pipeline.
