It has been increasingly popular to build VoiceoverIP (VoIP) applications based on Peer-to-Peer (P2P) networks in the Internet. However, many such VoIP applications freeride the network bandwidth of Internet Service Providers (ISPs). Thus their success may come at a cost to ISPs, especially those on the edge of the Internet. This paper explains the VoIP quality of Skype, a popular P2Pbased VoIP application. Specifically, using largescale end-to-end measurements, it first conducts a systematic analysis of Skype supernode network. This paper investigates the impacts of the access capacity constraint and the AS policy constraint on the VoIP quality of Skype.
