摘要
负载均衡是提高网络性能的重要技术,多实例生成树协议MSTP提出了在不改变网络交换基本方式的前提下,在不同的虚拟局域网VLAN中采用不同的生成树拓扑进行通信,通过控制各VLAN使用的生成树拓扑来达到选路的目的,为利用冗余链路实现负载均衡提供了条件。文中确定了一种链路负载函数作为衡量网络负载的依据,提出了一种基于MSTP的负载均衡选路算法,利用该算法可以选择链路负载最小的生成树映射,充分利用了冗余线路,实现负载均衡的目的。
Load balancing is a major technique to improve the network performance. Muhiple instances spanning tree protocol MSTP puts forward to communicate with different kinds of the spanning tree topology in different VLAN,on the assumption of without changing basic mode of switching network switching. Through controlling spanning tree topology that VLAN ued to choose way,if provided conditions for using redundant links to realize load balancing. This paper proposed a new function to estimate the effect of load balancing routing algorithm based on VLAN and MSTP. Lastly,it demonstrates that the routing algorithm can optimize load balance and shows its efficiency in simulating results.
