How to manage subordinate network history data of broadband line distribution system

摘要

The present invention relates to a sub-network history of a broadband line distribution system designed and implemented according to a relational data model in order to more quickly and accurately manage operation and maintenance data of network management systems connected to a sub-network of a broadband line distribution system (BDCS) The physical configuration of the system to which the subordinate network history data management method is applied is composed of a broadband line distribution system and subordinate systems connected thereto, and a logical configuration for managing the subordinate network history data management system includes subordinate network data management And the like.;In the subnetwork history data management method, the network management history data transferred between the manager and the agent is stored in the database defined according to the relational model, and can be processed as operational information to provide various information to the system operator.;The management data of the database is managed according to the recommendation of ITU G.784 for at least 10 days. The management data records the state of the system generated based on the time stored in the database, Through management, it is possible to grasp all history regardless of the installed positions of systems through the database which shows the operation status of devices connected to the network and the history of failure occurrence. Thus, the present invention provides a more efficient and economical function for network management of a broadband line distribution system.
