| With the rapid development of IP-based netwrok in Chinese carriers,IP network has become the important business bearer network of China Mobile,the operation and maintenance requirements of precisioin, the maintenance difficulty increasing.More and more patrolling item,the network scale is becoming larger and larger, but faced with less maintenance personnel, problems such as uneven skills and experience. So there is an urgent need for automated maintenance tools, help to improve the maintenance efficiency and precision, so that timely, take the initiative to find the hidden troubles in the network.This thesis is based on mobile IP bearer network, according to the patrolling items in the daily maintenance of mobile, puts forward the design of mobile IP network automatic patrolling system. The following is the main content, but also the system involves the main inspection daily operation of mobile.1. optical power patrol: gain optical port R/X power at regular time,support are classified by different manufacturers, porttype, transmission mode, rate and wavelength,setting different threshold,accurate judging whether optical power is greater than threshold and provide alarm.2. device KPI patrol: provide the device KPI patrol periodically,timeliness for IP bearer network device:CPU,memory,fan,power supply,temperature,port state and other health indicators were presented with abnormal alarm.3. configuration files analysis: configuration file is the soul of network device. The system can achieve the compare between device start and run configuration file.At the same time according to the mobile patrolling rules,edit scripts for compliance inspection of the configuration file.4. device log analysis: real-time receiving device log,according to the definition of alarm filtering rules automatically,fast extraction of the alarm content important,presented in alarm mode,and support and automatic screening key word definition.5.routing management:gathering device`s routing-table data before and after network cutover,comparing the routing changes. The service node reachability measured-way access to the network path by TRACEROUTE command to analyze the flow of business data, and intuitive presentation of business data flows to the network topology.providing OSPF, ISIS, BGP, MPLS routing protocols detection.6. instruction patrol: according to the daily maintenance instruction,providing visual configuration interface,positioning possible keywords,outliers,check periodically,and showed abnormal condition inspection.7. link patrol:provide to difine custom link information,including source device,the target IP.ping packets,packet size is arranged in the periodic task,to monitor the status of the link,and detailed records of link port traffic situation,provide statistics and analysis of custom time.8.Physical line inspection: Check the port IO exception alarm transmission error rate as well as send and receive packets.Get port SDH alarms and error messages, when the port SDH value growth change, to provide timely warning information, assist in the analysis of transmission problems.9. Configuration management and control: According to the specification of the IP bearer network can define your own templates to configure various configuration script, after import Mobile Scheduling-list, automatic generation of device configuration script; various checks in accordance with the China Mobile Group specification, the system can be custom configuration check compliancerules for the device configuration file.The above is the main function of patrolling system and provide to different forms of each function.this can help to grasp the whole network and device running state for maintenance person. |
