Question

The next three questions are related to the local area network shown below. In this network computers attached to links 1 & 2 send data to the server attached to link 3. The three devices are connected through a router. Link 1 Link 2 Link 3 Following parameters of the network have been provided. Propagation delay in link 1-138 micro seconds Propagation delay in link 2-309 micro seconds Propagation delay in link 3-216 micro seconds Frame size 1432 bytes ACK frame size 100 bytes Data rate100 Mbps Link 1 uses a stop-and-wait and link 2 uses a Go-back-N sliding window protocol with window size of 3 frames flow control respectively. What is the throughput on link 1? Consider only the throughput from the computer to the router. Express your answer in Mbps to two decimal points. Assume that the processing delay at all nodes are negligible
