Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a processing capacity measuring device, and more particularly to a processing capacity measuring device for measuring the processing capacity of information communication equipment.

[Conventional technology]

The conventional method for measuring the processing capacity of information and communication equipment is to apply a load to the device under test from a pseudo load device installed externally, and measure the occupied time of the central controller in the device under test. By measuring, the occupancy rate etc. were calculated from the relationship between the load and the occupancy time, and the processing capacity was measured.

[Problem to be solved by the invention]

In the conventional method of measuring the processing capacity of information communication equipment described above, the device under test measures the occupancy time and calculates the occupancy rate, etc., so it is necessary to incorporate this type of software into the device under test itself. In particular, in order to perform detailed measurements, a large amount of software is incorporated and processing is required, so there is a problem in that measuring the processing capacity will reduce the processing capacity of the device to be measured itself. Furthermore, when the occupancy rate of the device under test becomes high and approaches 100%, the occupancy rate itself output from the device under test cannot necessarily be trusted; Another problem is that it is not possible to grasp the operating state of the device under test.

The purpose of the present invention is to avoid making any changes to the device under test.

The configuration includes a packet receiving device that monitors and receives data, and an information processing device that has a function of analyzing the received data received by the counter circuit and the packet receiving device and calculating the processing capacity of the information communication device.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

A data line 21 is connected to the packet communication device 16 . Information lines a and b are connected to external terminals provided in each device between the processing capacity measuring device 1 shown in FIG.
, c, and d are connected.

Next, the operation will be explained.

Prior to starting the measurement, the tester sets the measurement mode and measurement time using the external input/output device 30. At the same time, the pseudo load generator 20 is started to operate. Based on the above settings, the information processing device 9 instructs the counter circuits 2 and 3 and the packet receiving devices 4 and 5 to start collection after setting the collection mode. The information processing device 9 itself is equipped with a timer circuit. The central control unit 19 generates pulses at regular intervals during call processing to the connected information line a, and does not generate pulses during rest. When the counter circuit 2 receives the generated pulses, the counter circuit 2 receives the generated pulses. is notified to the information processing device 9.

The information line C is connected to the common bus 8, and the information line d is connected to the packet communication device 16 to monitor and take in packet data sent and received between each device and between each system. The packet data taken in by the packet receiving devices 4 and 5 are compared with a plurality of patterns stored in advance in the packet storage device 6.7, and if they match, the packet receiving devices 4 and 5 store the matched packet data. is transferred to the information processing device 9. The information processing device 9 that receives the pulse reception notification or the data transfer adds the reception time to the data and stores it in the storage device 10. When the end command from the tester or the time specified in advance by the start command arrives, the above-mentioned operation ends. The collected data is output to a data output device of the information processing device 1, for example, transferred to a floppy disk. The data stored on the floppy disk is processed by another computer.

FIG. 3 is a flowchart of a packet data collection operation according to an embodiment of the present invention.

When measurement starts, the packet data is read in step 31, compared with the comparison pattern stored in the packet storage device in step 32, and it is detected in step 33 whether or not they match, and if they match, step 34 is performed. time information is added and stored in the storage device. This operation is repeated until the time or end command is received.
