Link 4 4 5 A file of size K = 200 KBytes is to be sent from Node 1 to Node 5 traversing four identical intermediate links as shown in Figure below. The data link protocol operating on node 1 requires that V = 100 bits be added as overhead to any frame transmitted on the link. Assume the link transmission rate is R = 100 kb/s while the link propagation time, Tprop is equal to 1 msec. Node processing delay is ignored. An intermediate node can start transmitting the received frame immediately when it is fully received. Link 1 Link 2 Link 3 2 3 R R Tprop Tprop a) (4 points) If the file is NOT segmented at node 1, but rather sent as a whole together with the overhead V, compute the total transmission time, Ttotali, till the file is completely received at Node 5. b) (6 points) For this part assume the file at node 1 is divided into frames each of size F bits. Of course, as before V overhead bits are added to F data bits at node 1 before transmission on link 1. The figure below shows the case of dividing the frame into m frames. R R
