| 摘 要： | 基于兴趣域的"快递式"动态负载平衡算法从HLA/RTI提供的服务出发,当节点成为重载节点时,将节点部分负载转移到兴趣域内的轻载节点上,同时采用两次"握手"方式解决了负载迁移过程中出现的问题.通过使用两个评价参数--CPU占有率和内存使用率进行实验证明,负载平衡前后重载节点的CPU利用率和内存使用率有明显差别,结果表明该方法能有效地平衡系统各节点之间的负载,保证系统的实时性,提高系统的服务质量.

| Abstract: | The express load balancing algorithm based on area of interest starts from the service provided by HLA/RTI,migrates some load from heavy node to light node in area of interest.Meanwhile,the method uses twice "handshake" to solve the problem appearing during the load migration process.By using two evaluation parameters,the CPU usage and the memory usage prove that the heavy load node's CPU usage and memory usage varies obviously before and after load balancing.The result shows the express load balancing algo... |
