Consider the speed of propagation of a signal along a cable is 2 x 108 m/s and network has 10 Mbps CSMA/CD network interconnectir ten computers shown in below image. Each computer is connected to the hub with a cable of different length. Computer H1 is connected v 100 m cable, computer H2 via a 200 m cable, computer H3 via a 300 m cable and so on upto computer H10, which is connected via a 1000 m cable (ignore the requirement of repeater due to signal degradation). Assume that the hub introduces a delay of 2.5 microseconds. What is the shortest packet length Lmin of this network in order to ensure that the CSMA/CD protocol functions properly?
