摘要
企事业单位为了提高与因特网互联的速度和可靠性,通常设置多条链路与因特网互联.但是出现了某些链路负载过重,而另外一些负载过轻的问题,通过在多条链路的出口处增设一个链路均衡器可以实现各条链路中的负载均衡功能.本文提出链路负载均衡技术,分析了链路负载均衡的特点,利用SNAT技术实现双向数据流的引导,提出计算链路负载的公式和正常状态随机法、最短路由最小负载法两个均衡算法.
To improve the speed and dependability of connecting Intemet, it is necessary for organizations to set several links to access Intenet. To actually balance traffic across multiple physical links a load controller is set at the outlet of the links and the technology of load balancing in multi-link is put forward in this paper. On the basis of analyzing the feature of load balancing in links, we propose the SNAT technology, the formula calculating link load and two algorithms.$$$$
