Question: Consider the operation of protocol 6
Consider the operation of protocol 6 over a 1-Mbps error-free line. The maximum frame size is 1000 bits. New packets are generated 1 second apart. The timeout interval is 10 msec. If the special acknowledgement timer were eliminated, unnecessary timeouts would occur. How many times would the average message be transmitted?

Does the protocol work correctly for MAX_SEQ = 4, for example?Suppose that we model protocol 4 using the finite state machine model. How many states exist for each machine?
