Measurement of MPEG-2 Video Streams through a Differentiated Service Domain

There is growing popularity of real-time Internet traffic such as audio and video streams. Such traffic benefits from receiving a different level of service from the network than more traditional data traffic. Schemes for providing differing network service for different applications have been proposed under the name QoS (Quality of Service). We investigate the performance of one such scheme by using a testbed to transmit both video and data traffic. In this paper we report on measurement techniques used in the testbed to report on performance and describe several problems and their solution.
