CECS 474 Computer Network Interoperability Assignment 2 Due Wednesday, September 23, 2009 (Your may turn this in this assignment either hand-typed or handwritten at the end of lab.) Given the following information about a network: A two-hop network between source A and destination B. The transmission links are T1 lines with bandwidth 1.544 Mbps * . Propagation delay across the line is 2.0 * 10 8 meters/sec. We wish to send a 100 Mbit message from source A to destination B. I. How long does it take for the message to reach destination B if circuit switching is used? You may assume: the call set-up/confirmation/teardown messages are all 100 Bytes long. the processing delay for set-up/confirmation/teardown messages (at all

Unformatted text preview: nodes A, B or C) is 0.01 second. II. How long does it take for the message to reach destination B if packet switching is used? You may assume: the overhead for each packet (header plus trailer) is 512 bits. the maximum packet payload size is 5000 Bytes (not including the header). the store-and-forward delay at each node is 0.001 seconds. no errors occur during transmission. Dr. Tracy Bradley Maples (Fall 2009) Source A Destination B 3500 kilometers 700 kilometers Node C * Note: When considering transmission media and transmission rates, M (Mega) = 10 6 . When considering data files for transmission, M (Mega) = 2 20 . Dr. Tracy Bradley Maples (Fall 2009)...
