A variable bit rate (VBR) AF flow contracts a committed information rate (CIR) of 1000 bytes/sec from a service provider and a peak information rate (PIR) of 10000 bytes/sec. For simplicity, assume that the packets are of 500 bytes in length. The network provider decides to mark the traffic with a two rate three color marker (trTCM) with PBS=500 bytes and CBS=500 bytes in color blind mode. Please verify the operation of trTCM algorithm in the following scenarios when a user sends conforming and non-conforming traffic by updating the bucket counts appropriately at various instants of time. Your goal is to test the outcome of trTCM and check the marked traffic in terms of the marked traffic bandwidth. The purpose is also to test the parameter settings. Consider up to 40 packet transmissions. The scenarios are: 1. The flow sends 1 packet every 0.5 seconds. Is the flow conforming according to the contracted rates? 2. The flow sends a burst of 2 packets (equally spaced) every 0.1 seconds and off for 0.9 seconds. What are the average and peak rates of this flow? 3. If the flow is sending traffic as per contract and if trTCM is not marking correctly, set proper values for PBS and CBS to make it correct.
