Abstract

As VoIP applications become increasingly popular, voice quality remains the user´s biggest concern. Peer-to-Peer network can potentially obtain qualified relay nodes (QRNs) to make path switching when the QoS of a default path degrades. Locating quality relay nodes rapidly and inexpensively however is a very challenging task. In this paper, we design and develop a sophisticated system to take snapshots of network status among PlanetLab nodes. We collect the 1-hop QRNs of all low quality sessions (LQSs) in a network snapshot. Based on collected data, we evaluate the state-of-the-art relay node locating approaches (e.g. EDR, EBP and ASAP).
