Method for managing data communication network

Abstract

The invention discloses a method for managing a DCN (Data Communication Network), and relates to the field of DCNs. The method comprises the following steps: a network management server sends instruments of automatically discovered adjacent DCN nodes to network elements; the network elements acquire data and send back; network element fiber exports are obtained according to network element port numbers; adjacent network fiber imports are obtained according to adjacent network element port numbers; routes are added at the network fiber exports and between adjacent network element fiber imports; routing array is displayed after adjacent network elements are processed; the network management server sends destination network element IPs and mask-off codes to next hop network elements, initial network element inquire a route table to obtain next hop network elements and send back; the network management server remarks the routes from the initial network element to the next hop network elements, and send the destination network element IPs and mask-off codes to the next hop network elements; the destination network elements cycles to next hop network elements; and the route from the initial network element to the destination network is obtained and displayed. The method can achieve visible DCN management, improves network failure processing efficiency, and can be applicable to a PTN (Packet Transport Network), an OTN (Optical Transport Network), an SDH (Synchronous Digital Hierarchy), an MSTP (Multi-Service Transfer Platform) and other networks.

Description

technical field [0001] The present invention relates to the field of DCN (Data Communication Network, data communication network), in particular to a method for managing a DCN network. Background technique [0002] As an important component of a telecom operator's network, the DCN plays a very important role in the operator's service control and network protection. The DCN is the communication channel for the network management system to manage network elements, that is, the transmission channel for network management information. Therefore, high-reliability maintenance, precise fault location, and fast fault handling of the DCN network all put forward an urgent need for effective management of the DCN. The Chinese invention patent application with application number 03128375.6 and titled "Automatically Switched Optical Network Node Communication Structure Organization Method Based on Embedded Communication Channel Technology" discloses the following technical scheme: using...

Problems solved by technology

However, this invention patent application only involves the use of ECC for DCN communication within ASON equipment and between ASON equipment, and does not involve the management of the DCN network by the network management system, that is, only to ensure the smooth completion of DCN communication between equipment, and Does not provide effective and convenient visual management for DCN maintenance

In addition, the invention patent application is only applicable to ASON equipment nodes, limited by the underlying network technology, and cannot be applied to PTN (Packet Transport Network, packet transport network), OTN (Optical Transport Network, optical transport network), SDH (Synchronous Digital Hierarchy , Synchronous Digital System), MSTP (Multi-Service Transfer Platform, multi-service transmission platform based on SDH) and other communication networks of various technologies
