Optimization Design And Implementation Of Gansu Mobile CMNET/IP Metropolitan Area Network

With the rapid development of Internet services,Gansu mobile by a single mobile operator to Internet information transformation operators,business development from mobile communication services to mobile Internet plus fixed broadband business development.Since 2016,Gansu mobile broadband network to carry out large-scale construction.Because the business needs of the increasingly rich,the rapid development of mobile Internet and broadband services,bandwidth demand from low bandwidth to the original high bandwidth demand,CMNET metropolitan data network has become the key to the development of business.The CMNET metropolitan area network data structure of the original has been unable to meet the rapid development of business.This paper analyzes the network technology related to the construction of CMNET metropolitan area network data,and according to the network status and business development needs.The optimization scheme of the network structure of the core router and the capacity expansion network link is established.According to the core layer,the service control layer and the construction principle of CMNET,the structure of the network is adjusted.Established IP address,VLAN planning principles,QoS deployment principles,network structure security principles.According to the core layer?the service control layer and the construction principle of CMNET,the structure of the network is adjusted.Established IP address,VLAN planning principles,QoS deployment principles,network structure security principles.According to the current network structure of CMNET network,two new nodes are added.At the same time,the increase of the core nodes around the city to the provincial trunk four core node router uplink,to ensure that the core nodes around the city up to export bandwidth to meet the needs of the business.According to the optimal neural network structure,optimize the routing strategy,develop a clear route organization principle and route configuration specification of the whole network of IGP and BGP to optimize the routing rules,deployment and configuration,to achieve a reasonable distribution of the traffic and load sharing.The application practice in Gansu mobile CMNET metropolitan data network,and achieved good results.
