Assume that the propagation speed is 2 × 108 meters/sec, and the distance between source and destination is 10,000 km. 1. Now suppose there is only one link between source and destination, and there are 10 FDM channels in the link. The MP3 file is sent over one of the channels. What is the end-to-end delay?Assume that the propagation speed in a coaxial cable is 2 ∙108 m/s a. Packets are transmitted using the ABP (alternate bit protocol) over a full-duplex 5-km coaxial cable with a 5 Mbps transmission rate. The packets and ACKs are 1500 bits long. The transmitter and receiver use a CRC chip and their processing time is negligible. How many packets are transmitted every second when there is no transmission error? b. Five transmission lines identical to the one discussed in a) are connected in series. A buffer is used at each connection between the links to store packets as required. How many packets will go through the five lines every second when there are no transmission errors? Now assume that a packet or its acknowledgement is corrupted on any given link with probability p. What is the new packet transmission rate through the five links? Comment. Assume the processing delays and queuing delays for both ends are negligible.88.
