Title: Voice Over the Internet: The Statistics of Calls, Packets, and Silence Suppression
Author(s): William S. Cleveland*+ and Hui Chen and Bowei Xi
Companies: Purdue University and Purdue University and Purdue University

Keywords: Internet traffic ; Long-range dependence ; Point processes ; Time series
Abstract:

Voice communications, long provided by the "public switched telephone network," is moving rapidly to the internet under the name Voice over Internet Protocol (VoIP). But little empirical study of VoIP traffic characteristics has been carried out. Data collected from the Global Crossing Network are used to study the statistics of call arrivals and durations, the multiplexed packet arrival point process, and silence suppression. These statistical properties play a critical role in traffic engineering.
