Abstract : In this thesis the nature of variable bit rate (VBR) traffic, as generated by a video teleconferencing application, in an Ethernet environment is studied. Analysis of the data retrieved from a testbed using metrics such as the rescaled adjusted range statistic, variance time curve, and index of dispersion for counts illustrate the self similar nature of traffic generated by a video teleconferencing application. This information is useful in formulating accurate models to support the various classes of traffic that will dominate the broadband ISDN (B-ISDN or ATM) infrastructure and in developing adequate access control mechanisms for those classes of traffic. The future of wide area networking will see Ethernet LANs populating the access points of ATM WANs, thus making use of the ATM transport mechanism for wide area communications. This thesis reports on work pertaining only to the traffic offered by the Ethernet LAN. Java and the Simple Network Management Protocol (SNMP) provide the means with which to construct tools for gathering and simulating VTC traffic. Java applets were written to measure and simulate VTC traffic.
