A- 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 ackets waiting for output link Suppose that the packet length is L-12000 bits, and that the link transmission rate along the link to router on the right is R-1000 Mbps. (i) What is the transmission delay (the time needed to transmit all of a packet's bits into the link)? Transmission delay would be L/R 12000/1000 12 seconds (ii)(ii) what is the maximum number of packets per second that can be transmitted by the link? (1+1
