摘　　要：针对AIMS系统服务端交换网络中存在的设备结构不清晰,广播域未隔离,设备及链路均无有效备份手段等问题,在AIMS V系统服务端交换网络设计中,利用园区交换网络设计所普遍采取的层次化方法,构建"核心层+汇聚层"的基础网络结构,并使用依据用户部门隔离冲突域的方式划分多VLAN;在汇聚层至核心层的链路上配置冗余链路,利用PVST协议实现客户端流量负载均衡和故障时自动切换;采用链路捆绑和HSRP协议实现两台核心交换机网关的互为热备运行方式,实现高可用性.实验结果证明上述方法可以提升交换网络的运行效率及维护便利,减轻网络设备故障对管制用户的影响,为AIMS V系统安全稳定运行奠定基础.Aimed at the problems in AIMS system with service-end switching network that its structure is vague,its broadcast domain is not isolated,and it lacks effective backup for equipments and links and employing hierarchical method generally used for switching network design in local network,a basic networked structure with ＂core level plus convergence level＂is set up and multi-VLAN division is made,where user-dependent conflict isolation mode is used.Besides,a redundant link is disposed between the core level and convergence level to realize load-balancing of flow at user-end and automatic switching in case of failure by using PVST protocol.Besides,link-binding and HSRP protocol are also used to achieve gateway hot standby execution of two sets of core-switch boards with high availability.It is verified by experimental results that by using foregoing method,the execution efficiency and maintenance convenience of the switching network is improved and the influence of failure in network device on user controlling is alleviated,so that laying a basis for safe and stable operation of AIMS V system.
