A NETWORK PERFORMANCE EVALUATION METHOD BASED ON SIMULATING TECHNOLOGY AND MEASURING TECHNOLOGY

With the rapid development and prevalence of computer network,a method of measuring and evaluating network systems' performance is needed so as to make network run healthily and even improve its level of service and administration.After thorough study of the traditional methods,i.e. resolution,simulating and measuring, this paper presents a mixed method based on both simulating and measuring. The main idea is to measure and evaluate the existing network using a simulating load produced artificially. The authors argue in detail with the evaluating model, measuring methods and evaluating algorithms of this method, then briefly introduce its implementation. The results of experiment show that this method inherits the traditional advantages of not only the simulating method, i.e. wide application and high accuracy,but also the measuring method, i.e. verity, reliability and adaptability.Furthermore,it avoids their flaws, such as inelasticity,high costing of the former and poor flexibility,high expenditure of the latter.
