Suppose host A has M Bytes to send to host C along the path through packet switch B which employs store and forwarding switching. A B C X Assume that there is no processing delay and no queuing delay at any node. The propagation delay and the transmission rate of link A-B is T seconds and R bits per second, respectively. The propagation delay and the transmission rate of link B-C is T seconds and R bits per second, respectively. Suppose that the header added to each packet (irrespective of the size of the packet) is always N Bytes. Assume that there is no other traffic on the network. No acknowledgements are sent. How much time does it take to send all M Bytes of data as one packet from Host A to Host C? Write the final expression in the space provided. You are not required to provide a justification.
