Packet Loss Correlation in the MBone Multicast Network

Maya Yajnik, Jim Kurose, and Don Towsley, UMass Amherst

One-line summary: Losses on backbone or between NI and receiving process are rare; the average loss event is a single packet, but the average lost byte lives in a burst packet loss; most packets are dropped close to the source.

Overview/Main Points


Many proposed mcast error control protocols recover by interacting with nearby receivers rather than requesting source retransmission, so it's worth profiling whether loss patterns make it reasonable to expect that a nearby receiver will have gotten the packet if you didn't get it. (Paper concludes that it is reasonable to expect this.)
