Suppose we want to send a file that is 2 x 106 bits (2 Mega bits) long over a network of four routers as shown in Figure (a). Each link has a data rate of 1 Mbps. Assume the propagation and processing delays are zero or negligible, and the header sizes are also negligible. The packet switches operate in store-and-forward mode; i.e. each switch must first receive all bits in a message or segment before it starts to transmit it to the next hop. Without message segmentation (i.e. one message for the whole file) how long it takes until the entire file is received by the destination? Now suppose the file is segmented into 200 messages (segments), each 10,000 bits long. How long it takes until the entire file is received by the destination? Activate Win Compare the delay between the two cases and explain the difference. Go to Settings to a. Source b.
