Project Abstracts Return to QoS Routing for VoIP Projects End-to-end Delay Modeling and Synthesis   Student: Hong Li, Ph.D. student Supervisor: Prof. Lorne Mason Abstract: End-to-end delay is one of the most important factors that impact VoIP quality. We have studied the stochastic characteristics of the end-to-end delay measurements in an overlay network owned by a network operator in Asia. We developed a synthesis method based on the shifted gamma distribution, which fitted the real end-to-end delay measurements well. We also proposed a method to synthesize new network delay trace based on the mean network delay of the trace. [Full Description] [Paper (pdf format)]
