摘　　要：在基于以太网的企业网络实施中,既要考虑到单点链路故障问题给网络带来的可用性影响,同时又要考虑增加冗余链路带来的网络不稳定问题。解决的办法是在网络中部署2条以上的链路解决单点故障问题,同时在汇聚层交换机上部署基于VLAN的快速生成树协议,既可解决环路问题,又可以充分利用冗余实现流量负载均衡。另外,在面向终端用户主机的第一跳冗余协议中,部署虚拟路由器,增加路由冗余,防止路由单点故障。提出了在三层设备上部署RSTP+HSRP实现双通道负载均衡,并用Packet Tracer工具进行了模拟,验证了基于RSTP+HSRP的双通道负载均衡是可行的,并分析了其中的工作原理和过程,给出了在企业网中部署基于RSTP+HSRP的双通道链路实现负载均衡的方法,对同类型的企业网部署和优化有一定的指导和借鉴意义。In the implementation of an Ethernet-based enterprise network,it is necessary to consider the availability impact of a single-point link failure problem on the network,and at the same time,consider the network instability caused by the addition of redundant links.The solution is to deploy more than two links in the network to solve the single-point failure problem,and deploy a VLAN-based rapid spanning tree protocol on the aggregation layer switch,which can solve the loop problem and make full use of redundancy to achieve traffic.Load balancing.In addition,in the first-hop redundancy protocol for end users,virtual routers are deployed to increase routing redundancy and prevent single-point failures of routing.It is proposed to deploy RSTP+HSRP on the three-layer device to realize dual-channel load balancing,and the Packet Tracer tool is used to simulate the dual-channel load balancing based on RSTP+HSRP is feasible,and the working principle and process are analyzed.The method of deploying dualchannel links based on RSTP+HSRP in the enterprise network to achieve load balancing is given,which has certain guidance and reference significance for the deployment and optimization of the same type of enterprise network.
