Abstract: For the issue that more and more popular P2P voice and video transmission application cause great pressure for the underlying communication network, this paper provides the scheme of measuring Skype network topology, and analyzes Skype protocols, communication mechanism and traffic characteristics. Based on analyzing lots of active measuring experimental data and passive capturing communication traffic of Skype, it provides the communication mechanism of Skype, and finds out partly traffic characteristics and protocol behavior characteristics of Skype. Through tests, these conclusions can be used to analyze and control Skype in the LAN environment.

Key words: Skype network, network measurement, traffic characteristics
