METHOD FOR EXTRACTING PERFORMANCE DATA FOR MANAGING CLIENT NETWORK IN MULTI-LAYER DATA NETWORK

摘要

PURPOSE: A method for extracting the performance data for managing the client network in the multi-layer data network is provided to minimize the network load and the data extracting time in the remote data base, to reduce the query number to the remote data base and also to prevent the unnecessary results from being returned. CONSTITUTION: A performance data collecting means for directly collecting and storing the performance data corresponding to the management individual out of the performance data generated in the multi-layer data network and a client management network are network-connected. After the connection is completed, the performance data extracting notification signal received from the performance data collecting means is sent to the client management network means. Out of the notification signals received, the available performance-extraction time and the management individual list are detected and analyzed. According to the results of the analysis, the data extracted according to the query data is stored in the client management network and the step is performed in the form of a single query statement.
