Web service request distribution based on object set

摘要

Aiming at the workload features of web service business request, the request distribution algorithm based on object set is put forward in web service cluster system. The content distribution of web service request, the workload of web service server and the performance degradation of web service server are taken into account in this algorithm. Based on the system model of queuing theory, the system model is put forward and the cost function and reward function are defined and the optimized solution is obtained. With the least cost of request migration of the system, the algorithm can select the server with best performance. Experimental results show that the average response time of the proposed algorithm is less than LARD by 12.2% and throughout is improved by 18%.
