基于NAT的Free BSD负载均衡网关研究

The Load Balancing Research of Free BSD Based on NAT Gateway

为了达到最佳的负载均衡效果 ,将负载分给多个服务器分担。负载控制器需要根据网络流量状态和服务器资源来分配负载 ,这就需要应用优化的负载分配策略 ,达到平均分配负载的目的。本文讨论了特定流量条件下网关数目的计算模型 ,分布式路由策略实现负载分配的策略的方法 。

In order to achieve the optimum load balancing effect,the load should be shared by some servers. The load control machines have to distribute the load according to the state of network outflow and the sources of the servers, so it needs to apply the optimizing load distributed strategy to achieve the goal of average distributed load.This paper has discussed the computing model on the condition of specific outflow, the method of the load distributed strategy achieved by distributed route strategy, and the method of achieving load balancing gateway, which is based on the network adress transfer in the Free BSD Unix.
