# Throughput

Please reference this figure for the question:

16. Calculate the THROUGHPUT between Points B and G for the following cases:

a. The media is copper with a length of 150,000 meters. The data rate is determined by multiplexing of 24-128kbps sources with a 10% overhead. Frame length is 500 bits. A Go-Back-N protocol is used (W=127) and the probability of error on the link is 10-8 .. Assume BPSK modulation.

b. The media is free space using satellite communications. The data is the same as in part a. The distance is 70,000 km. A Go-Back-N protocol is used (W=127) and the probability of error on the link is 10-5.... Assume BPSK modulation.

Answer

a) throughput is the average rate of successful message delivery over a communication channel. This data may be

delivered over a physical or logical link, over a wireless channel, or that is passing through a certain network node, such as data passed between two specific computers. The throughput is usually measured in bits per second (bit/s or bps), and sometimes in data packets per second or data ...
