Abstract :
This paper evaluates the differentiated services (DiffServ) mechanism proposed by IETF to provide QoS and resource reservation under bursty Web traffic. Particularly, the performance of the weighted fair queuing (WFQ) algorithm is studied, using a two-node network configuration. A realistic Web workload model generating the aggregation of Web-accessing traffic flows is developed and used to evaluate the performance. Our analysis demonstrates that due to the burstiness of Web traffic, DiffServ cannot achieve all the desired QoS guarantees, especially packet delay and jitter
