Problem 5 Refer to Chapter 1 P31 for definition of message segmentation (hint: this is analogous to letting the cars travel separately as opposed to traveling together in the caravan analogy). Suppose the source has a message of 1 Gbit to be sent to the destination via a 3-link path (through two packet switches). Each link has a capacity of 10 Mbps and a propagation delay of 0.1 seconds. Ignore queuing and processing delays What is the end-to-end delay to send the message without segmentation? What is the end-to-end delay if the message is sent with segmentation into 500 packets, of 2 Mbit each? a) b) c) Repeat a) and b) when there are 10 links (i.e., 9 packet switches) between the source and the d) e) What are the benefits of message segmentation? destination Suppose now that each packet needs a header of 1 Kbit. Repeat the calculation in b) (for the 3- link case) f What are the drawbacks of message segmentation
