Consider the following method for controlling the congestion in the error-free virtual circuit subnet. A router may only transmit ACK for the received packet if it knows packet transmission along the virtual circuit through the subsequent routers is successful. Assume that each router utilizes the stop-and-wait ARQ and offer one buffer (large enough for one packet) for every VC in every direction of traffic. If each router takes T sec in order to transmit the packet (data or ACK) to the next router and there are N routers on the VC, at what rate data packets are delivered to the destination host?
