Suppose a TCP Vegas connection from A to B passes through abottleneck router R. The RTTnoLoad is 50 ms and the bottleneckbandwidth is 1 packet/ms. (a). If the connection keeps 4 packets inthe queue (eg =3, =5), what will RTTactual be? What value of cwndwill the connection choose? What will be the value of BWE? (b). Nowsuppose a competing (non-Vegas) connection keeps 6 packets in thequeue to the Vegas connection’s 4, eventually meaning that theother connection will have 60% of the bandwidth. What will be theVegas connection’s steady-state values for RTTactual, cwnd andBWE?
