气象网络中策略路由的设计与实现

Design and implementation of policy routing in meteorological network

由于气象网结构比较复杂,用户众多,且外存在多个对外出口,有着很多的特殊要求,普通目的地址路由表已无法满足要求。文章提出了多出口气象网环境中流量分配控制的解决方案,基于策略路由(PBR)的设计和网络地址转换(NAT)等关键技术,实现不同源、不同目的网段的数据包由指定的接口进出,从而达到提高网络速度、实现网络资源共享的目的。

Because meteorological network structure is complex with more users and many outlets, the general purpose address routing table is unable to meet many special requirements. This paper presents the solution of flow distribution control in multi-outlet meteorological network environments and puts forward key technologies of policy based on routing（PBR）design and network address translation （NAT） ,which achieve non-source and non-network data packages accessing the specified interface so as to imorove the network speed and sharing cyber source.
