Description
Technical Field
The present invention relates to the field of computer communications technologies, and in particular, to a method, an apparatus, a device, and a medium for traffic management.
Background
The three-layer topological structure information of the IP bearing network comprises equipment information and connection link information between equipment, and the accurate topological structure is very important for the work of network operation and maintenance, network planning, service opening and the like. The existing three-layer topology maintenance method mainly comprises three modes of pure manual maintenance, port address mask matching based and port description matching based. The pure manual maintenance mode is used for maintaining equipment and link information in a mode of manually inputting an Excel form or a system after related personnel operate on the current network; the method based on port address mask matching needs to manually input the equipment into the system, then the system regularly acquires the address and mask information of each port of the equipment through an SNMP protocol, and then matches the ports of the addresses in the same network segment according to the address and the mask and forms link information. The method based on port description matching also needs to manually input the equipment into the system, then regularly acquires the description information of each port of the equipment through an SNMP protocol, and then forms link information according to the matching of the description information of the ports.
In summary, the pure manual maintenance, the matching based on the port address mask and the matching based on the port description all require manual maintenance of the device information, which also brings the accuracy problem of manual maintenance when the manual maintenance is needed, and the accuracy of the topology data in the actual work is low due to the reasons of incorrect SNMP password, delay in timing discovery and the like.
