基于OSPF的陕西省气象宽带网络整合设计

Design and Integration of OSPF-Based Meteorological Broadband Network for Shaanxi Province

针对陕西省气象局宽带通信网络中移动、电信和广电等3家通信运营商线路并存,IP地址使用杂乱等现状,以及无法方便地实现多链路负载均衡和链路之间自动切换等突出问题,采用了规范3家运营商链路接入的连接方式,应用全国统一的新IP地址,特别是在全网范围内部署OSPF动态路由选择协议等一系列措施。充分发挥OSPF协议的特点,合理地划分区域,并根据需要针对不同链路配置了不同或相同的OSPF代价,使得不同链路间自动切换和流量自动负载均衡得以轻松实现。经过测试,整个网络的设计和实现,充分发挥了多条链路的效益,提高了网络系统的稳定性,达到了设计的预期目标,可以为其他部门网络设计提供较好的借鉴。

There are three problems in the Shaanxi Provincial Meteorological Service broadband communications network： the coexisting of three telecom suppliers,the messy using of IP addresses,and being unable to meet the requirement of multi-link loading balancing and automatic switching between links.To solving those problems,a series of methods are adopted,such as standardizing the access methods for CMCC,CTC,and BCTV,and using the national unified IP addresses,and especially deploying the OSPF Dynamic Routing Selecting Protocol in the whole network.By adopting the OSPF protocol and such methods as dividing area reasonably and setting different configurations for the same or different OSPF costs as required,the automatic switching between different links and the traffic load balancing can be easily realized.The test indicates that the benefits of the multi-link network are fully used,and the stability of network increased.The system can be used as references for the network designing of the like departments.
