Method and system for opening a data communication network

Abstract

The invention discloses a method for opening a data communication network (DCN). The method includes: an access network element and a non-access network element respectively generate a network element management IP address according to a preset management address generation rule; The element management IP address is configured on the management loopback interface, and an OSPF routing instance of the DCN is created; when the status of the Ethernet interface is determined to meet the preset conditions, an Ethernet sub-interface is created, an IP address routing table of the DCN is generated, and the network element information Configured to the OSPF routing protocol; EMS analyzes the information of each network element sent by the access network element, creates a logical network element corresponding to the non-access network element, and establishes a connection with the non-access network element. The invention also discloses a DCN opening system at the same time.

Description

technical field [0001] The present invention relates to the related technology of opening a data communication network (DCN, Data Communication Network) in a packet transport network (PTN, Packet Transport Network), in particular to a DCN opening method and system. Background technique [0002] For a newly deployed PTN device network, after all devices are successfully connected at the physical layer, the DCN needs to be enabled first, so that maintenance personnel can monitor each network element (NE, Net Element) for remote centralized deployment and monitoring of telecom services. As the scale of PTN equipment network deployment continues to increase, the labor cost of deploying the DCN network is also increasing. [0003] At present, the industry usually uses the built-in Internal Gateway Protocol (IGP, Internal Gate-way Protocol) routing instance, such as: through the Open Shortest Path First (OSPF, Open Shortest Path First) bootstrapping method to automatically establ...

Problems solved by technology

[0004] The latest equipment manufacturer's DCN solution has added the function of automatically generating IP addresses. However, the IP generation rules of each manufacturer lack a unified plan, and IP addresses between different equipment manufacturers may conflict, which cannot satisfy a mixed equipment manufacturer. The demand for automatic provisioning of the DCN network affects the flexible planning of the operator's network

In addition, the network management system is usually deployed on a high-performance computer or other visual control system, and does not participate in the IGP route learning of the device network, and cannot directly perceive the device information in the network. It is necessary to manually create logical network elements in the network management system.
