Consider a sender using a reliable data transfer protocol. The sender wants to send 9 packets to a receiver. The transmission delay for a single packet is 40 milliseconds. The propagation delay between the hosts is 100 milliseconds.
Assume an ACK is small enough that you can ignore its transmission delay. You may also assume that no packets are lost, damaged, or reordered.
For this question, a reliable data transfer is considered finished when all ACKs have been received by the sender.

A is connected to B and C via a broadcast channel—a packet sent by A is carried by the channel to both B and 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 B and C, such that A will not get new data from the upper layer until it knows that both B and C have correctly received the current packet. Give FSM descriptions of A and C.Consider a network with 4 links between two hosts where the maximum allowable packet size is 1000 bits; each link has a transmission rate of 2000 bits per second, except the second link has a transmission rate of 1000 bits per second. How long does it take to send 6000 bits from one host to the other? You may ignore propogation delay, assume there is no other traffic on the network, and assume that no routers drop packets due to queue length. Round your answer to two decimal places.
