Application-layer multicast implements the multicast functionality at the application layer. The main goal of application-layer multicast is to construct and maintain efficient distribution structures between end-hosts. In this paper the authors focus on the implementation of an application-layer multicast network using PlanetLab. They observe that the total time required to measure network latency over TCP is influenced dramatically by the TCP connection time. They argue that end-host distribution is not only influenced by the quality of network links but also by the time required to make connections between nodes. They provide several solutions to decrease the total end-host distribution time.
