Statistical inference for internal link parameters in a network

摘要

In this paper we describe the use of end-to-end loss measurements of multicast traffic to infer the network-internal loss characteristics. For the case that the tree spanning a multicast source and its receivers is known, we present statistically rigorous techniques for estimating loss rates on the paths between branch points based on losses observed by multicast receivers. Last, we show how these techniques can also be used to identify the structure of the tree spanning a multicast source and its receivers.
