Evaluation of 10Base-T and 100-Base-T Ethernets Carrying Video, Audio, and Data Traffic

Multimedia applications integrate a variety of media , namely, audio, video, images, graphics, text, and data. These media have diierent bandwidth, delay, and loss requirements. Data traac is predominantly bursty and it requires reliable service from the network, but it can tolerate delay. In contrast, audio and video traac is stream-oriented, it can tolerate some loss of data, but it requires delivery within a bounded delay. To support multimedia communications, it is desirable to use existing network infrastructures, which are designed speciically for data applications. In such existing network infrastructures, Ethernet is the most popular LAN scheme used. In this work we have simulated 10Base-T and 100Base-T Ethernet segments carrying constant bit rate audio/video streams and data traf-c (bursty and non-bursty). Given the stream rate, stream delay and loss constraints, as well as the data load and burst size, we have determined the number of streams supportable.
