Research on Resource Management System for Railway Data Communication Network Based on NetFlow and SNMP Protocols
To improve the resource management as well as operation and maintenance efficiency of the railway data communication network,this paper studies the resource management mechanism for the data communication network.NetFlow and SNMP protocols are used to achieve automatic data collection on the equipment resources,IP resource utilization situation,service online status and service behavior characteristics of the railway data communication network.Test environment design,resource management system development and deployment as well as field testing are conducted to verify the resource management mechanism for railway data communication network based on the NetFlow and SNMP protocols.The proposed resource management system can profile the service flow,and describe such service attributes as source port,destination port,protocol,traffic volume,service type and location.It can achieve the dynamic monitoring of IP address resources,simplify the statistical calculation,analysis and allocation of IP addresses,and improve the utilization efficiency of IP resources.
