Description

Design a Data packet duplicate suppression mechanism on multicast face.

ccnd's algorithm is:

  • Multicast datagram face should delay every outgoing Data packet for a random duration (on the order of 10ms).
  • During the delay of a packet, if an identical packet is received on the face, cancel the send.

but it causes packet reordering and cannot adapt to link condition.

This Task is to design a better algorithm for duplicate suppression.

Category is currently "Faces", but the design MAY propose to put part of this feature in Forwarding/Tables if necessary.
