摘要:
 气象传输的预报产品和基础数据种类繁多、实时和非实时数据传输时效不一样,需要分流非实时的业务数据从而减轻系统负担。方法是通过链路选择、流量负载均衡和链路冗余测试、业务化运行( Track)技术在两条链路的网络设备进行优化,采用访问控制列表配置区分实时和非实时数据传输业务,拟解决系统流量高峰时动态合理分配网络资源的问题。测试结果表明：正常运行状态下实时和非实时数据业务能够有序清晰地进行合理分流传输达到主要和备用链路融合；当出现通信链路中断,该系统能够在迅速不干扰业务正常运转的状态下转换至可利用的链路上,保证业务传输数据的不间断。经过业务化试运行,Track技术可以实现气象数据业务分流传输。
Abstract:
 Forecast products and the basic data of meteorological transmission range are various,real-time and non real-time data trans-mission timeliness is not the same,need to shunt the non real-time operational data so as to reduce the burden of the system. The method is through the Track technology to optimize the network equipment in the two links,using access control list configuration distinction be-tween real-time and non real-time data transmission business,solve the reasonable allocation problem of traffic peak system dynamic net-work resource. The test results show that the normal operation mode for real-time and non real-time data services can be orderly and clear preparation link transmission in the main reasonable diffluence. When the link is broken,the system can without affecting this busi-ness case quickly switch to the available link,ensuring uninterrupted service data transmission. Through the test operation,Track technolo-gy can realize the transmission of meteorological data service distribution.
