Question

7. Consider a communication channel with a one-way propagation delay of 100 msec and transmission rate of 100 Mbps. There is no processing delay and the size of the ACK packets may be ignored. Answer each part below, making sure to show your computations (a Find the round-trip delay-bandwidth product. (b) If the Go-Back-N protocol is to be used for the above channel with packet size of 1000 bytes what is the minimum window size that must be used to achieve 100% utilization? the 1 e long packets. If pack ets are transmitted continuously, how long does it take for the s that is, to go from 0 up to numbers to wrap around, d to count individual transmitted bytes. How ve except that the transmission rate is 1 um sequence n and back to 0? (d) Now suppose the 32-bit sequence nmbers long does it now take for the sequen to wrap around? (e) Repeat the above parts for channels identical to Gbps and 10 Gbps respec two cases. Instead, display your answers for all three channels (withtransmission rates of 100 Mbps, T Gbps, and 10 Gbps) neatly in table form for each part of the question tively. There is no need to show your detailed computations for these

Explanation / Answer

Q a.

Bandwidth Delay Product = bandwidth (bits per sec) * round trip time (in seconds).

Answer => 20000000                       

Q b.

You require to send packet at 0.20008/0.00008 = 2501
