An access-level network topology management method and system

Abstract

The invention discloses an access-level network topology management method and system, the method comprising: a gateway network element in the network obtains the network topology of the entire network and the connection relationship between network elements, and according to the acquired network topology and network element The connection relationship between generates a topology tree with the gateway network element as the root node; the gateway network element records and maintains all topology node information on the topology tree, and the topology node information includes at least the network element level and network element status. The invention proposes a topology management method based on the topology automatic discovery and management of the master control panel for network devices in the access layer, and realizes the automatic collection, maintenance and management of the entire network topology.

Description

technical field [0001] The invention relates to a network topology technology, in particular to an access-level network topology management method and system. Background technique [0002] With the continuous expansion and upgrading of access-level telecom operators' networks, the number of network elements continues to increase, and the traditional SDH (Synchronous Digital Hierarchy, Synchronous Digital Hierarchy) network is gradually converted to packet Ethernet. Independent network elements are managed independently. According to the existing network management structure, every time a new network element is added, the operator needs to configure its IP, so that the network management can realize the maintenance and management of the new network element. This configuration is particularly cumbersome when the operator adds many devices at a time. This requires that the network management system can be automated to the greatest extent to realize automatic discovery of netw...

Problems solved by technology

In this way, the initiative of network management is not on the gateway network element. If the client does not initiate an IP application for some reason, or the application message is lost for some reason, the gateway cannot find the client network element and cannot perform IP allocation.

In addition, DHCP allocation can only achieve IP allocation. To achieve network topology collection, additional protocols are needed to support it. In this way, the transmission and interaction of network packets must be increased in the network, increasing the risk of network congestion and wasting resources. limited bandwidth
