Design of Municipal Meteorological Information Network System
[Purposes]With the gradual advancement of meteorological observation automation and busi-ness informatization,the monitoring and transmission of meteorological data has increased geometrically,which puts forward higher requirements for the carrying capacity of the network transmission system,so it is necessary to build a stable,reliable and safe network system.[Methods]Combined with the informa-tization requirements of high-quality meteorological development and the actual business needs of Lia-ocheng Meteorological Bureau,in terms of system construction,the stability of line transmission is ensured through measures such as line redundancy,stacking technology and link aggregation,and in the later op-eration and maintenance,real-time monitoring of the physical environment,network equipment status,and line on/off of the computer room is realized through the dynamic environment monitoring system and eSight management.[Findings]Line redundancy and core switch stacking measures are used to avoid the impact of line faults and single points of failure on service operation,and link aggregation technology im-proves the bandwidth and reliability of backbone links,effectively ensuring the normal operation of ser-vices.The dynamic environment monitoring system and eSight can realize the real-time monitoring of the environment,equipment,and line status of the data center,which is convenient for operation and mainte-nance(O&M)personnel to quickly locate and troubleshoot after receiving alarms,and improve fault han-dling efficiency.[Conclusions]Based on the actual needs of the business,the deployment of the network system of Liaocheng Meteorological Bureau in construction and O&M was completed to ensure the stable operation of meteorological services 7×24 h.
