Assume you have a 10 Mbps CSMA/CD network interconnecting ten hosts. Each computer is connected to the hub with a cable of different length. Host H1 is connected via a 100 m cable, Host H2 is connected via a 200 m cable, and so on up to host H10 that is connected via a 1000 m cable (ignore the signal degradation problem). The speed of propagation is 2.5x108 m/sec. The minimum frame length used in this network so that CSMA/CD protocol will function correctly should be __________________ bits.
