Method for realizing relocation based on EML-NML interface of CORBA

Abstract

The invention relates to a method for realizing floating based on a CORBA-based EML-NML interface. The EML-NML floating interface adds an EMS encapsulation layer, including the interface-side encapsulation layer and the EMS-side RPC agent. The EMS encapsulation layer encapsulates the interface provided by EMS in the form of dynamic library and source code tight coupling into a network based on TCP / IP communication frames. Remote call interface, the communication frame transfers the function type, parameters and return results of the call between the EMS system and the interface system; the release of the interface system CORBA implementation object adopts the manufacturer name, the unique ID number of EMS in the private network domain and the object name common naming method. Networking method: Divide the access layer private network into multiple private network groups, and each private network cluster corresponds to a group of EML-NML floating interface systems running on the same multi-homed host; the NMS system manages the EMS through the multi-homed host . Using the method of the invention enables the interface system to have network portability, saves IP addresses, facilitates centralized management of interfaces, and reduces networking cost and complexity.

Description

technical field [0001] The present invention relates to a design scheme for separate operation of network element management layer-network management layer EML-NML interface and network element management system EMS and its related networking applications, in particular to a network based on the common object request agent architecture CORBA The meta-management layer-network management layer EML-NML interface realizes the floating 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 managemen...

Problems solved by technology

[0016] The present invention aims at the deficiencies and defects of the above-mentioned existing network management, and provides a new method for realizing floating of the EML-NML interface. The present invention enables the interface system to have network portability, referred to as the EML-NML floating interface, and mainly solves the following three problems: Big problem: (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 for stability and security considerations, use commercial CORBA software You need to pay the basic software fee for each EMS; 3) Since the interface and EMS are distributed all over the network together, it is inconvenient to maintain
