| 摘 要： | 针对省级气象部门骨干网络存在一些普遍问题,如不同线路没有实现负载分担,备用线路往往带宽闲置;省市间"不对称路由"对远程视频会议等业务的效果有影响;没有针对不同的业务做带宽控制,不同业务间存在相互影响等,采取了一些技术手段。引入策略路由对数据传输进行分流,同时发挥出多条线路的效益,实现了负载分担,并克服了"不对称路由"的现象,保证视频会议的效果。引入一系列QoS(服务质量)策略,对线路上不同业务占用带宽进行管理,既保证实时数据传输和视频会议`等关键业务的带宽,同时又为其他业务提供了动态的带宽资源,充分利用现有的网络带宽。经过测试,整个网络的优化升级,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。

| Abstract: | There exist some common problems in the backbone network of provincial meteorological services. The load sharing, for example, has not been achieved in different network lines, so that the backup line is often idle, and the asymmetric routing between provinces and cities has an effect on remote video conference service. There is no control of bandwidths for different tasks, and there are mutual influences among different tasks. Some technical means are proposed aiming at above problems. Through introducing the policy routing to shunt data transmission, the benefits of multiple lines are improved, so the load sharing is realized, and the problem of asymmetric routing is solved, so that the effect of video conference is guaranteed. The occupied bandwidth of different tasks on lines is managed by introducing a series of QoS strategies, which can not only ensure the bandwidth of key tasks such as real time data transmission and video conference, but also provide dynamic bandwidth resources for other tasks, thus to make full use of the existing network bandwidth. A series of tests indicates that the optimization and upgrade of the entire network has reached the design target, which provides a good reference for the network design of other departments. |
