3. (a) In the context of TCP congestion control, (i) Describe the operation of window-based congestion control and name one common algorithm for achieving this. (ii) Suppose the Round Trip Time (RTT) between the sender and the receiver is 100ms, the packet size is 1kB and the window size is 10 packets. What is the sending rate of the sender in kb/s ? [10 Marks] (b) Describe how fairness and efficiency are achieved by TCP Congestion Control. [10 Marks] (c) In the context of active queue management (i) Describe the operation of the Random Early Detection (RED) scheme which is used when congestion builds up in buffers. (ii) Illustrate how Weighted Random Early Detection (WRED) is used to treat traffic marked by a policing function
