Abstract

A data sampling apparatus includes a plurality of first-in first-out memories and a processor that executes a procedure. The procedure includes classifying received data signals in accordance with types of the data signals; storing the classified data signals in the corresponding memories; calculating a sampling rate based on a ratio between a total traffic volume of the received data signals per given time and a traffic volume of data signals stored in each of the memories per given time; and sampling the data signals stored in each of the memories based on the corresponding calculated sampling rate.

Claims

1. A data sampling apparatus comprising:

a plurality of first-in first-out memories; and

a processor that executes a procedure, the procedure including;

classifying received data signals in accordance with types of the data signals;

storing the classified data signals in the corresponding memories;

calculating a sampling rate based on a ratio between a total traffic volume of the received data signals per given time and a traffic volume of data signals stored in each of the memories per given time; and

sampling the data signals stored in each of the memories based on the corresponding calculated sampling rate.

2. The data sampling apparatus according to claim 1, wherein

the sampling rate is calculated based on a value obtained by squaring the ratio between the total traffic volume and the traffic volume of the data signals stored in each of the memories.

3. A method of sampling data, the method comprising:

classifying received data signals in accordance with types of the data signals;

storing the classified data signals in a plurality of corresponding first-in first-out memories;

calculating a sampling rate based on a ratio between a total traffic volume of the received data signals per given time and a traffic volume of data signals stored in each of the memories per given time; and

sampling the data signals stored in each of the memories based on the corresponding calculated sampling rate.

4. The method according to claim 3, wherein

the sampling rate is calculated based on a value obtained by squaring the ratio between the total traffic volume and the traffic volume of the data signals stored in each of the memories.

5. A computer-readable recording medium storing a program for causing an apparatus to execute a procedure, the procedure comprising:

classifying received data signals in accordance with types of the data signals;

storing the classified data signals in a plurality of corresponding first-in first-out memories;

calculating a sampling rate based on a ratio between a total traffic volume of the received data signals per given time and a traffic volume of data signals stored in each of the memories per given time; and

sampling the data signals stored in each of the memories based on the corresponding calculated sampling rate.

6. The computer-readable recording medium according to claim 5, wherein

the sampling rate is calculated based on a value obtained by squaring the ratio between the total traffic volume and the traffic volume of the data signals stored in each of the memories.
