Description

An Operation and Management System of Distributed OXC based on CORBA}

The present invention relates to an optical cross-connection (hereinafter referred to as OXC) system. More specifically, the present invention relates to a method of communication between objects of operation maintenance, management control, and network management control function in an OXC operation management system. By using CORBA (Common Object Request Broker Architecture), COBA-based distributed OXC operation management system can access the COVA-based distributed OXC system and perform operation maintenance and management control efficiently.

In general, a distributed system refers to a system in which each computing resource operating independently of each other is logically integrated through a shareable communication mechanism such as a network. The most distinctive feature of such a system is that it can integrate local or logically distributed information and transparently fulfill and provide the processing requirements for the application or user.

In addition, distributed systems can share computing resources such as hardware or software that are distributed across multiple independent systems. Economical, easy to expand and reconfigure into new systems, as well as portability, interoperability, scalability, and reliability because of avoiding duplication of installation costs due to additional features.

COVA-based distributed OXC operation management system, which has recently been gaining attention, is more diverse and complex than the conventional centralized management system, and thus, there is a problem that the efficiency of distributed OXC operation management is inferior because related tools are not provided sufficiently. As a result, several types of distributed management system development and management tools have been announced in recent years, but the development of the OXC operation management system is still in its infancy.

Operational management of the OXC generally refers to operational preservation and administrative control of a type of network equipment. ITU-T G.872 and 709, and Telcordia's GR-3009, provide basic information on operational integrity and administrative control of the various subsystems that make up the OXC system.

Accordingly, there has been a growing need in the art to develop a distributed OXC operation management system structure that can efficiently provide operation maintenance and management control for COVA-based OXC systems that provide a distributed computing environment.

The present invention has been proposed to solve the problem that the efficiency of the OXC operation management is lowered because the related tools for the operation maintenance and management control of the distributed OXC operation system as described above is not provided sufficiently, in the development of the OXC operation management system By using object-oriented modeling, object management, management control, and network management control functions and the use of COVA as a method of communication between these objects, it is effective for the OXC operation management system that maintains, redesigns, and scales the OXC system. The purpose is to provide a COVA-based distributed OXC operation management system structure that can be applied.
