| 摘 要： | 在分析了现有的网络负载平衡方案的基础上，针对采用集中式负载调度的集群系统中普遍存在的网络瓶颈的问题，提出了基于虚拟路由技术的缓解方法。首先对LVS进行了网络瓶颈问题的分析，并针对存在的问题提出了采用虚拟路由技术，调度器与服务器配对技术与增加网卡相结合的缓解网络瓶颈问题的方法。在FreeBSD5．2下实现了一个负载调度系统，称之为FSS，其支持虚拟路由，和服务器与调度器的配对，其它功能与LVS在IP层调度时基本相同。经实验验证，该方法达到了缓解网络瓶颈的目的。

| Abstract: | On the base of analyzing the present load balance technique, and the network bottleneck problems in the center dispatching cluster system, a kind of technique based on the virtual route was put forward to solve the problem. In the FreeBSD, a load dispatching system was realized which is called FSS and supports virtual route and the partnership between the server and the dispatcher. Other functions are similar to those of LVS in the IP layer dispatch. According to the results of the experiment, a conclusion has been drawn that this technique does well and meets the need. |
