地市级气象核心网络扁平化改造

随着气象系统业务内容的不断扩展，原气象核心网络在性能，稳定性和运维效率方面逐渐难以满足需求.为保障网络系统高效可靠运转，对网络现状进行研究并提出改造需求，详细设计网络改造方案和设备割接步骤，基于网络虚拟化和可视化融合运维平台，采用新一代CSS和iStack交换机堆叠技术，对气象核心网络进行了平滑升级改造，组建扁平化大二层气象网络系统.通过改造简化了网络结构，提高了网络效能和运维效率.

Flatened Rebuild of Municipal Meteorological Core Network

With the continuous expansion of business in meteorological system, the performance, stability, and maintenance efficiency of original core network have been short of capacity to meet the demand. To guarantee reliable and efficient operation of meteorological network system, current status of the network has been studied and rebuild demands are proposed, network reform schemes and equipment changeover procedures have been designed in detail, a new generation of CSS and iStack switch stacks technologies have been adopted in smoothly upgrading the meteorological core network based on network virtualization and visual fusion operation and maintenance platform, overall built a 2 layer flat meteorological network system. By rebuilding, the network structure is simplified, and the network performance and maintenance efficiency are improved.
