There are some defects such as inconvenience and maintenance trouble for network management in the traditional C/S (client/server) model of network management system.Therefore, we put forward a network management system that based on B/S (browser/server) model, in which the original C/S model of network management system is turned to B/S model, and the structure of system is optimized which helped the customers to conveniently and reliably monitor and manage the network resource.This system is based on the interface that the original network management system server exposed, uses the RMI (remote method invocation) technology call server interface to realize data communication with Web server, and the whole system adopts the load balancing strategy to balance the access requests from multiple browser to each Web server for processing.Meanwhile, the system adopts the hot standby process on the single load balancer, thus greatly improves the overall performance and reliability of the network management system.
