Calculate the latency (from first bit sent to last bit received) for the following: (a) 100-Mbps Ethernet with a single store-and-forward switch in the path and a packet size of 12,000 bits. Assume that each link introduces a propagation delay of 10 us and that the switch begins retransmitting immediately after it has finished receiving the packet. (b) Same as (a) but with three switches. (c) Same as (a), but assume the switch implements "cut- through" switching; it is able to begin retransmitting the packet after the first 200 bits have been received.

Assume a 10Mbps Ethernet has two nodes, A and B, connected by a 360m cable with threerepeaters in between, and they each have one frame of 1,024 bits to send to each other. Further assumethat the signal propagation speed across the cable is 2*10^8 m/sec, CSMA/CD uses back-off intervals ofmultiples of 512 bits, and each repeater will insert a store-and-forward delay equivalent to 20-bittransmission time. At time t=0, both A and B attempt to transmit. After the first collision, A draws K = 0and B draws K = 1 in the exponential back-off protocol after sending the 48bits jam signal. a. What is the one-way propagation delay (including all repeater delays) between A and B inseconds? At what time is A's packet completely delivered at B? b. Now suppose that only A has a packet to send and that the repeaters are replaced with switches.Suppose that each switch has an 8-bit processing delay in addition to a store-and-forward delay.At what time, in seconds, is A's packet delivered at B?
