Research on Computation of Web Request-load Based on a New Telescopic Fuzzy Sets
Calculation of Web request load is an important prerequisite for the realization of Web server clusters loadbalancing, usually fuzzy mapping can be used to achieve this purpose, but if the fuzzy system was designed according to the conventional method, the system maybe show Rules Explosion phenomenon, because the diverse types of Web requests need many system inputs, which lead to the fuzzy rules Exponential increase with the growth of the number of input variables. Therefore, a kind of telescopic triangular fuzzy sets was studied, it can changes the division of fuzzy sets non-uniformly by adjusting the stretching factor, and substantially reduces the number of the rules in the same input range. Based on the fuzzy sets, a fuzzy controller was constructed to calculate the Web request load for the loadbalancing of Web server cluster. The simulations show that the servers can run at a high efficiency and get very good load-balancing results.
