基于IRF2和LACP MAD的气象网络设计研究

DESIGN AND RESEARCH OF METEOROLOGICAL NETWORK BASED ON IRF2 AND LACP MAD

气象内网传统架构基本采用VRRP和MSTP的组网模式。针对传统模式下,设备性能的利用率不高,网络管理工作繁杂,网络架构不能满足气象信息业务发展需求等问题,基于IRF2和LACP MAD对地市级气象内网进行优化设计和平滑升级。对升级后的虚拟化网络系统原理、工作过程、分裂冲突过程进行详细分析。通过模拟软件对升级后的网络系统进行分裂测试、抓包分析,结果表明该网络性能及可靠性均优于现有网络。该设计方案同样适用于省级气象网络核心和接入层的平滑升级。

The traditional architecture of meteorological intranet basically adopts VRRP and MSTP networking mode.Under the traditional mode,the utilization rate of equipment performance is not high,the network management is complicated,and the network architecture cannot meet the needs of meteorological information business development.In order to solve these problems,based on IRF2 and LACP MAD,the optimization design and smooth upgrading of city level meteorological intranet were carried out.We analyzed in detail the principle,working process and conflict splitting process of the upgraded virtualized network system.Split test and packet capture analysis were performed on the upgraded network system through simulation software.The results show that the network performance and reliability are better than the existing network.The design scheme can apply to the smooth upgrading of the provincial meteorological network core and access layer.
