Performance Measurement and Analysis of H.323 Traffic

  • Conference paper

Part of the Lecture Notes in Computer Science book series (LNCS,volume 3015)

Abstract

The popularity of H.323 applications has been demonstrated by the billions of minutes of audio and video traffic seen on the Internet every month. Our objective in this paper is to obtain Good, Acceptable and Poor performance bounds for network metrics such as delay, jitter and loss for H.323 applications based on objective and subjective quality assessment of various audio and video streams. To obtain the necessary data for our analysis we utilize the H.323 Beacon tool we have developed and a set of Videoconferencing tasks performed in a LAN and also with end-points located across multiple continents, connected via disparate network paths on the Internet.
