摘要: It has been increasingly popular to build voice-over-IP (VoIP) applications based on peer-to-peer (P2P) networks in the Internet. However, many such VoIP free-ride network bandwidth of Internet Service Providers (ISPs). Thus their success may come at a cost ISPs, especially those edge In this paper, we study quality Skype, P2P-based application. Specifically, using large-scale end-toend measurements, first conduct systematic analysis Skype supernode network. We then investigate impacts access capacity constraint and AS policy Skype. show that even when free-riding is no longer possible for only 20% supernodes are located stub overall degrades significantly, large percentage sessions will have unacceptable quality. This result clearly demonstrates potential danger building P2P without taking into account operational models also time diversity traffic patterns reduce preceding
