C Suppose An Application Generates Chunks Of 120 Bytes Of Data Every 20 Msec And Each Chunk Gets Encapsulated In A Tc 1 (150.01 KiB) Viewed 67 times

(c) Suppose an application generates chunks of 120 bytes of data every 20 msec, and each chunk gets encapsulated in a TCP segment and then an IP datagram. What percentage of each datagram will be application data? Show your working. [4 marks] (d) TCP congestion control aims to transfer data at a rate just below that at which the network would become congested. Assume the TCP Slow Start Threshold is 8 at transmission round 1, and all packets were received normally from transmission round 1 to transmission round 14, apart from a triple duplicate ACK event that occurred just after transmission round 8. (i) Draw a table two co nns: the first column the number of transmission rounds from 1 to 14, and the second column is the number of packets being sent at the corresponding transmission round with TCP Tahoe. (ii) During which transmission round was the 16th segment sent? Show your working. [7 marks] [3 marks]
