| Abstract: | Web services is a very important technology ofinternet applications. How to improve its performance is a hotpot. Dynamic load-balance is introduced to web services to augment its fault-tolerance and scalability. The current situation of load-balancing algorithm is reported. The necessity of web services load-balance is analyzed, and on this basis a dynamic load-balance model is proposed. Methods are presented in the framework to dynamically determine the resource consumption value of services and to adjust the load-thresholds and the weights of servers. Measures are also discussed for overload protection. |

| Keywords: | web services load balance threshold service consumption overload protection |
