Asst. 6 Solution. Fall 2010 Problem 1. Three stations, A, B and C, are attached to a common cable as shown. The stations are using CSMA/CD. Propagation times (one way) are shown. a) Draw a space-time diagram with time going down vertically, and use it to answer the remaining parts. Solution. b) If A begins transmission of a packet at time t, what is the range of times that C might start sending so as to cause a collision? Show the explanation with the aid of the space-time diagram. Solution. t-6 to t+6. c) If C began to send just before the latest point causing collision in the range found in b), what is the largest duration of a frame that A could send to B such that it would all be received without a collision? Solution. 10-2 = 8 milliseconds . d) If A and C are at the extremes of the network and the minimum frame duration was chosen so a collision anywhere would result in a collision everywhere, what must this minimum frame size be? Solution. 2*6 = 12 milliseconds
