In this paper, Class Based Weighted Fair Queue (CBWFQ) algorithm with generic traffic shaping mechanism was simulated on an IP router for applications bandwidth guarantee. IP Telephone, Voice and HTTP are the traffic classes generated in the network. CBWFQ scheme classify packets, assign bandwidth to each packet class and queued packets in a buffer for transmission. Network simulation environment consisted of two students each carries IP telephone, voice and HTTP traffic was constructed using OPNET modeler, simulation software. Simulation results was studied and analyzed. Graphical results show that each traffic class met with the minimum bandwidth guaranteed and, classes get shaped according to their specified traffic rate (bits/sec).
