1. A communication link has a bit rate of 10 Gbps and a length of 20 km. Propagation velocity is 2.5 108 m/s and ACK frames are piggybacked on information frames going in the reverse direction, one ACK for every received frame. Information frames are 9000 bytes long. The frame header is 100 bytes. (a) What is the minimum window size that maximizes the e ective bit rate? (b) What is the information e ective bit rate if the window size is 16 frames? 1.
