1) Computing the one hop transmission delay (2 pts) Consider the figure below, in which a single router is transmitting packets, each of length Z 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= 4000 bits, and that the link transmission rate along the link to router on the right is R= 1 Mbps. 1- What is the transmission delay (the time needed to transmit all of a packet's bits into the link)? 2- What is the maximum number of packets per second that can be transmitted by the link? 2) Computing end to end delay (3 pts) Consider the figure below, with three links, each with the specified transmission rate and link length. ------ +Link 1 Link 2 +Link 3 Transmission rate: 10 Mbps Link Length: 2 km Transmission rate: 1000 Mb Link Length: 2 km Transmission rate: 10 Mops Link Length: 500 km Find the end-to-end delay (including the transmission delays and propagation delays on each of the three links, but ignoring queueing delays and processing delays) from when the left host begins transmitting the first bit of a packet to the time when the last bit of that packet is received at the server at the right. The speed of light propagation delay on each link is 3x108 m/sec. Note that the transmission rates are in Mbps and the link distances are in Km. Assume a packet length of 8000 bits.
