“…Assume that router s is the ancestor node of both a and b. Assume that the sender uses unicast to send messages to receivers, and assume that packets are sent in a back-to-back pair 3 . For the k-th pair of back-to-back packets, denoted as a k and b k , sent from f to a and b, respectively, we use the following notation:…”

A Peer-to-Peer (P2P) network can boost its performance if peers are provided with underlying network-layer routing topology. The task of inferring the network-layer routing topology and link performance from an end host to a set of other hosts is termed as network tomography, and it normally requires host computers to send probing messages. We design a passive network tomography method that does not requires any probing messages and takes a free ride over data flows in P2P networks. It infers routing topology based on end-to-end delay correlation estimation (DCE) without requiring any synchronization or cooperation from the intermediate routers. We implement and test our method in the real world Internet environment and achieved the accuracy of 92% in topology recovery. We also perform extensive simulation in OMNet++ to evaluate its performance over large scale networks, showing that its topology recovery accuracy is about 95% for large networks.

“…Peer-to-Peer (P2P) networks have been broadly adopted for large-scale content distribution and online multimedia streaming [1,2,3]. As an application-layer solution, P2P networks need to deal with many problems introduced with churn, i.e., the user-driven dynamics of peer participation.…”
