More and more VoIP applications have emerged with the development of network and multimedia coding techniques. Their traffic identification is meaningful to for network management and application optimization. In this paper, a new traffic identification scheme, which combines traffic flow statistic analysis with host behavior estimation, is proposed to identify the VoIP traffic at transport layer...
With the success of P2P file sharing application and the development of multimedia coding technique, IPTV, a new emerging P2P application, arises on the Internet for streaming content. In order to gain insights into P2P IPTV systems, we have undertaken an in-depth measurement study of one of the most popular IPTV systems, namely UUSee, compared with BT-like file sharing application. The measurement...
Delay tolerant networks (DTNs) use a store-carry-forward communication model relying on the mobility of nodes because a persistent end-to-end path from source to destination generally does not exist. Being different from ad hoc, recent research in DTN is still in its infancy which mainly uses analytical model and simulation to analyze network protocols. As we all know, testbed is an important research...
