CIS – 3360 Security in Computing Grade total = 2% Total points = 70 Due Date = October 25 (Wednesday), 2006 Question 1 (5 + 5 + 5 = 15 points) Consider sending a large file of F bits from Host A to Host B. There are two links (and one router) between A and B, and the links are uncongested (that is, no queuing delays). Host A segments the file into segments of S bits each and adds 40 bits of header to each segments, forming frames of L = 40 + S bits. Each Link has a transmission rate of N bps. There is no propagation delay. Router R always processes a frame of size L after it receives it for L/2N seconds. Host A --------------- R --------------- Host B (i) When does the first frame arrive at Host B after Host A starts sending the frame at time T? (ii) Assume that the router R can send, receive and process simultaneously and A sends frames continuously (one after another), when will the second frame arrive at Host B? (iii)
