Question
Problem 1: Consider two stations, A and B, in a datalink network. A is 1km away from W The signal propagation speed is 200,000 km/second. The datalink has a bandwidth of 100Mbps The packet size is fixed at 1024 Bytes Answer the following questions: What is the transmission time for each packet? What is the propagation delay between A and B? Problem 2: To detect a collision, a station must first receives the collision signal from the place of collision, and it takes a small amount of time for the station to determine that indeed a collision has occurred based on the collision signal received. Assume that the latter is 1 microsecond- Answer the following questions (assuming the condition from problem 1 still applies):| If A and B happen to transmit a packet at the same time, how long does it take for A (or B) to receive the collision signal since the start of the transmission of the packet? If CSMA/CD is used, how much time can the station save compared against CSMA?Explanation / Answer
Problem 1:
Maximum packet transmission time = 1024
