Video Traffic Characterization for Multimedia Networks with a Deterministic Service

One of the most important traffic types in future packet-switched networks is high-bandwidth, variable-bitrate (VBR) video. Since video is a delay-sensitive media, the network must allocate resources to maintain quality-ofservice (QoS) guarantees on throughput, delay, and delay jitter to video connections. A key component of resource allocation is the traffic characterization of video sources that determines the resources required to support video connections. In this study, we propose a method for characterizing VBR vadeo traffic with a fixed number of leaky buckets in networks with a deterministicservice. We explore trade088 of network utilization in two directions: ( I ) the number of leaky buckets used for trafic characterization, and (2) the amount of informationfrom a video sequence used to produce the characterization. W e evaluate our method with a set of 30-minute long MPEG-compressed video traces.
