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.

Embodiment Construction

[0034] In the embodiment of the present invention, the access network element and the non-access network element respectively generate the network element management IP address according to the preset management address generation rules, configure the network element management IP address on the management loopback interface, and Create an OSPF routing instance of the DCN; when the status of the Ethernet interface meets the preset conditions, create an Ethernet sub-interface, generate the IP address routing table of the DCN, and configure the network element information to the OSPF routing protocol; EMS analyzes the access network element and sends Create a logical network element corresponding to the non-access network element, and establish a connection with the non-access network element;

[0035] Wherein, the network element information includes network element information of access network elements and non-access network elements.

[0036] figure 1 It is a schematic flow...

Abstract

The invention discloses a method for opening a data communication network (DCN). The method comprises the following steps: generating net element management IP (Internet Protocol) addresses by access net elements and non-access net elements according to a preset management address generation rule respectively, configuring the net element management IP addresses to a management loopback interface, and creating an OSPF (Open Shortest Path First) routing instance of the DCN; when an Ethernet interface state conforms to a preset condition as determined, creating Ethernet sub-interfaces, generating an IP address routing table of the DCN, and configuring net element information to an OSPF routing protocol; and resolving the net element information transmitted by the access net elements, creating logical net elements corresponding to the non-access net elements, and establishing connections with the non-access net elements by an EMS (Element Management System). The invention further discloses a DCN opening system.

Description

technical field [0001] The present invention relates to the related technologies 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, NetElement ) telecom services for remote centralized deployment and monitoring. 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, InternalGate-wayProtocol) routing instance, such as: Open Shortest Path First (OSPF, OpenShortestPathFirst) bootstrapping method to automatically establish DCN channels b...
