A2. Computing the one-hop transmission delay Consider the figure below, in which a single router is transmitting packets, each of length L bits, over a single link with transmission rate R Mbps to another router at the other end of the link. L: packet length (in bits) R: link transmission rates (Mbits/sec) Queue of packets waiting for output link Suppose that the packet length is L-8000 bits, and that the link transmission rate along the link to router on the right is R 10 Mbps. (a) What is the transmission delay (the time needed to transmit all of a packet's bits into the link)? (b) What is the maximum number of packets per second that can be transmitted by the link
