Unformatted text preview: LAN has total 8 stations (including A and B) and a bandwidth of 1 Mbits/s. The MAC protocol running on the LAN is CSMA/CD. Hosts A and B are located at the farthest two points in the LAN with the one way propagation delay of 0.5 msec. The propagation delay on the point to point link from B to A is 0.2 msec. A and B use Selective Repeat (with 4 bit sequence numbers). The data link layer frames are 1.4Kbits long. The probability that the medium is successfully captured by any station is observed to be 0.385. What is the average bandwidth available to the network layer for this communication? Assume that there are no bit errors. Ignore all headers and size of ACK frames. Clearly state any reasonable assumption you make, and explain your reasoning.
