【摘要】 文中通过分析气象业务时效性强、7X24小时不间断运行的特点,结合海南气象网络结构的现状,充分挖掘现有网络设备的功能,针对传统线路备份方法的不足,深入研究ECMP技术的逐包转发负载均衡方式、OSPF协议环境下ECMP应用和链路汇聚技术(MP),规划设计了基于ECMP的双运营商负载均衡方案,最大化利用了电信运营商线路,实现了具有高可用性、高带宽的省—市县气象网络。该网络已经投入业务运行两年,无论是在日常业务中还是在重大气象保障中都取得了良好的效果。更多还原

【Abstract】 In this paper,by analyzing the meteorological business of the time-critical,7X24-hour running characteristics,combined with the status of Hainan meteorological network structure to fully mining the capabilities of existing network equipment,for lack of backup methods of traditional lines,in-depth study of ECMP technology load balancing methods by-packet forwarding,OSPF protocol application by ECMP and link aggregation technology(MP),we are planning a two-Telecom operator based ECMP load balancing to maximize the use of the telecom operators’ line and achieve high availability of the province – town meteorological network.The network has been put into operation two years,whether in the ordinary course of business or in the major obstacle weather support has achieved good results.更多还原
