Consider a scenario in which Host A wants to simultaneously send packets III Hosts Band C. A is connected to Band C via a broadcast channel-a packet sent by A is carried by the channel to both Band C. Suppose that the broadcast channel connecting A, B, and C can independently lose and corrupt packets (and so, for example, a packet sent from A might be correctly received by B, but not by C). Design a stop-and-wait-like error-control protocol for reliably transferring packets from A to Band C, such that A will not get new data from the upper layer until it knows that both Band C have correctly received the current packet. Give FSM descriptions of A and C. Also, give a description of the packet format(s) used.
