I need the answer as soon as possible
Consider a point-to-point link between a source and a destination where the destination sends an acknowledgement (ACK) frame for every data frame that it receives successfully from the source. For each of the frame, the data payload is 320-byte long and the overhead is 80-byte long. Each ACK frame's length is the same as the overhead length of the data frame. The data rate of the link is 6.4 Gbps, the length of the link is 500 meters and the medium propagation speed is 2 x 10° meters/sec. Assume that the node processing delays and queuing delays are always negligible. (i) Compute the effective throughput of data payload in bps if Sliding Window flow control is used with a window size of 7. (ii) Compute the effective throughput of data payload in bps if Sliding Window flow control is used with a window size of 127. (iii) For a 64,000-byte message, compute the total delay of transferring the message to the destination if the Stop and Wait ARQ (Automatic Repeat reQuest) is used with a BER (bit error rate) = 2 x 10* in both data frames and ACK frames.
