Performance Evaluation how’s it going? METHODS OF PERFORMANCE EVALUATION If we are to design a network, we need to know whether the equipment is going to be used to best effect, and to achieve this we will need to be able to evaluate its performance. Methods for performance evaluation fall into two categories: measurement techniques, and predictive techniques; with the latter category comprising mathematical analysis and simulation. | Introduction to IP and ATM Design Performance With Applications Analysis Software Second Edition.

Methods for performance evaluation fall into two categories measurement techniques and predictive techniques with the latter category comprising mathematical analysis and simulation. Measurement Measurement methods require real networks to be available for experimentation. The advantage of direct measurement of network performance is that no detail of network operation is excluded the actual operation of the real network is being monitored and measured. However there are some constraints. A revenue-earning network cannot be exercised to its limits of performance because customers are likely to complain and take their business elsewhere. An experimental network may be limited in the number and type of traffic sources available thus restricting the range of realistic experimental conditions. Predictive evaluation analysis simulation In comparing analysis and simulation the main factors to consider are the accuracy of results the time to produce results and the overall cost of using the method this includes development as well as use . One advantage of analytical solutions is that they can be used reasonably quickly. However the need to be able to solve the model restricts 58 PERFORMANCE EVALUATION the range of system or traffic characteristics that can be included. This can result in right answers to the wrong problem if the model has to be changed so much from reality to make it tractable. Thus analysis is often used to produce an approximation of a system with results being produced relatively quickly and .
