we used the somewhat arbitrary measure of "power" to characterize network performance. The usual definition of power, P, is given by: load average delay (a) Explain why this definition of power is commonly used, and in what sense it is "arbitrary" (b) A commonly used approximation to the relationship between normalized load (which can 1 vary between 0 and 1 only) and average delay is d = -; where A is the normalized load 1-A offered to the network and d is the average delay of packets passing through the network. Find and sketch the value of power, P, as a function of the offered load for this network. Be sure to show the minimum and maximum values of power and load, as well as the value of offered load that maximizes the power. d (c) Now suppose we modify the definition of power to give more emphasis to throughput than X² delay, i.e. let us have P: Sketch the new power function against the offered load, being careful to show the maximum and minimum values of both load and power, as well as the value of load that leads to maximum power. Comment on why the value of load that maximizes the power is larger than in the previous part of the question we used the somewhat arbitrary measure of "power" to characterize network performance.
