Filed: 1999-12-22
Abstract: PURPOSE: A method for extracting service throughput using charging data in a network providing a virtual connection service is provided to supply the reliable throughput value and easily extract throughput. CONSTITUTION: In whole charging data stored in a network management system, charging data of a specific virtual connection to be analyzed during an arbitrary period is extracted(S1). It is judged whether PCR(Peak Cell Rate) field of transmission direction connection exists in the extracted charging data(S2). If exists, the contracted PCR to the connection of an originating side is used as it is(S3). If not exist, the contracted PCR to the connection of an originating side is calculated by adding the contracted permitted information rate of the originating side to the excessive information rate contracted in the originating side(S4). The contracted peak cell bit number to the connection of the originating side during elapsed time is obtained by multiplying the contracted PCR by elapsed time field value and one tenth(S5). The contracted PCR byte number is compared with total byte number transmitted from the originating side during elapsed time(S6). If total byte number is more than the contracted PCR byte number, excessive byte number is calculated by subtracting total byte number transmitted from the originating side from the contracted PCR byte number(S7). If not, the excessive byte number is set up as 0(S8). The through is obtained by using excessive byte number, total byte number transmitted from the originating side, and total byte number received in the destination side(S9).
