Online Performance Parameter Adjustment For Apache Server And QOS Performance Optimization

The internet has become the most important part of our life. The internet technology has had a significant impact to our life, and the network technology research causes more and more concern. Web service system is the important part of the network technology, which requires higher technology. Therefore, many experts and scholars pay attention to improving the performance of the web and the QOS guarantee.In this paper, the problem of the online performance parameters adjustment for Apache sever is solved based on the understanding of the Apache system structure, the way of treatment process and the resource allocation deeply. At the same time, the control scheme which can realize the real-time adjustment of the server performance parameters to optimize the performance of network is put forward. The control scheme is proposed based on the researching of the predecessor's methods. And combining with the practical work way of the web server, and the disadvantage of the previous methods in practical application is studied. According to the non-linear variable environment of the network, the fuzzy control system is used to realize the online adjustment and optimization of the server performance. The design makes the adjustment to be more convenient, and avoid the previous disadvantage. Considering the response time and the computer performance, two kind of fuzzy rules has are founded. The first set of fuzzy rule when optimizes the system load has the good effect, and the second set of fuzzy rule must surpass the first set of fuzzy rule in the request stacking speed. The matlab simulation results show that the adjustment performance is good. At last this article has simultaneously designed the user-friendly control page in web browser to convenience operation.In this paper, the fuzzy control scheme optimizes the performance of the network, improves the stability of the server, and ensures the QOS, at the same time, simplifies the network management operation, which has a good application prospect and practical significance.
