uestion Five The Trivial File Transfer Protocol (TFTP, RFC 1350) is an application layer protocol that uses the Stop-and-Wait protocol. To transfer a file from a server to a client, the server breaks the file into blocks of 512 bytes and sends these blocks to the client using Stop-and-Wait ARQ. Assume that the transmission time of one block is 2ms, and that of an acknowledgment is 2ms. Assume also that the sender uses a timeout value of 5ms. Show the pattern of transmissions and associated state transitions for the followin g sequence of events . The server transmits 5 blocks The third block is lost and the acknowledgment of the 2d block (not counting any resubmission) is lost Draw the flow control in the chart provided in the following page. Describe in details how the sender and the receiver will behave. Your graphs must show the sliding windows, the sequence number of the frames, and any special action performed by the sender of the receiver (15 marks)
