Problems solved by technology

[0016] The present invention aims at above-mentioned deficiency and defect of existing network management, provides a kind of networking method based on the EML-NML floating interface of CORBA, the present invention makes interface system have network portability, mainly solves following three major problems: (1) Each EMS needs to be assigned a backbone layer IP address, resulting in a large consumption of IP addresses; (2) Each EMS needs to install CORBA basic software. If commercial CORBA software is used for stability and security considerations, each EMS needs to Pay for the basic software; 3) It is inconvenient to maintain because the interface and EMS are distributed all over the network

Embodiment Construction

[0031] The EML-NML floating interface uses CORBA as the underlying communication model, and uses TMF.513, TMF.608, and TMF.814 specifications in TMF as the information model. The key to its architecture is that there is an EMS encapsulation layer and an RPC agent installed on the EMS side. This encapsulation layer and the RPC agent convert the functional interface provided by EMS in a tightly coupled form such as a dynamic library into a communication frame format based on TCP / IP and communicate with the network The form of remote call is completed, thus ensuring that the EML-NML floating interface can run on different network segments from the EMS system.

[0032] The present invention is a telecommunications management network EML-NML layer networking management scheme based on floating interface technology, mainly including a series of corresponding network communication protocols (TCP / IP, CORBA), a network address translation server, an interface server, Manage the EMS sys...

Abstract

The invention relates to a networking method based on a CORBA-based EML-NML floating interface. m private networks in the DCN access layer are formed into a private network cluster, each private network cluster corresponds to an interface server, and all EMS systems in the cluster The EML-NML floating interface runs on the interface server, and the private network IP of the interface server is statically converted to the public network IP of the DCN backbone layer by the network address server. Only the CORBA basic software is installed on the interface server, and the EML-NML floating interface passes through The public network IP statically assigned by the interface server communicates with the NMS system in the backbone layer, and communicates with all EMS systems in the private network cluster through the private network IP where the interface server is located and different ports. The advantages of the present invention lie in three aspects: saving public network IP addresses; saving basic software costs; simplifying interface management and maintenance; reducing the complexity of networking.

Description

technical field [0001] The present invention relates to a networking application based on CORBA-based network element management layer-network management layer EML-NML floating interface and network element management system EMS, and in particular to a network element management based on the common object request agent architecture CORBA Layer-network management layer EML-NML floating interface networking method. Background technique [0002] In order to improve the efficiency of telecom equipment operation and maintenance, telecom equipment operators began to build the network management layer NML unified network management - network management system NMS, and incorporated the network element management system EMS provided by each equipment supplier into the unified management platform. The communication facility between the NMS and each EMS is the Telecom Integrated Data Communication Network (DCN). The DCN network adopts a hierarchical management model and is divided int...
