CLAPS: A Cross-Layer Analysis Platform for P2P Video Streaming

Peer-To-Peer (P2P) networks are emerging as an interesting alternative to media streaming delivery with respect to Content Delivery Networks (CDN). Although several P2P protocols have been proposed to support video streaming with an adequate degree of Quality of Service (QoS), a critical point today is how to evaluate them and optimize their parameters. The difficulty lies in the fact that the behavior of the P2P overlay network and the one of the underlying packet network are closely related and need to be analyzed simultaneously. Ad-hoc simulators for each P2P architecture have been proposed but they neglect the interactions between peers and the underlying network.
