Abstract

PURPOSE:To measure instantaneously the response time an to compare and analyze the response time quantitatively by outputting respectively the response time of respective nodes. CONSTITUTION:At a terminal node 6, in which the measurement from a host node 3 instructed from an input part 1, the message for the on-line measurement is automatically generated and sent to the host node 3. At such a time, the passing time is set to the message for the measurement at respective relay nodes 4 and 5 and sent to the next node. At the host node 3 to receive the message for the on-line measurement, the arriving time to the host node 3 is set and sent to a return terminal node 6. At such a time, at the relay nodes 4 and 5, the passing time is set to the message for the measurement and sent to the next node. Next, at the terminal node 6 to receive the message for the on-line measurement, the measuring completion message is obtained, sent to the host node 3, and at the host node 3 to receive the measuring completion message, the measuring result is edited and outputted from an output part 2 and the measurement is completed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for measuring the response time of a distributed processing system in which the response time of the distributed processing system can be measured at each node of the distributed processing.

[Conventional technology]

Conventionally, the response time of this type of distributed processing system has had to be measured by feeling at the end device.

Furthermore, it was extremely difficult to compare and analyze the transit time of online messages at each node.

[Problem that the invention seeks to solve]

The above-mentioned conventional response time measurement method measures at the terminal, so it is necessary to go to the installation site of the terminal device to perform measurement, and there is a drawback that immediate response is impossible. Another drawback is that it is extremely difficult to quantitatively compare and analyze response times.

The purpose of the present invention is to eliminate such drawbacks and to make it possible to measure the response time of makeshift work in a distributed processing system using only instructions from a host computer, and to compare and analyze the message transit time of distributed processing at each node. An object of the present invention is to provide a response time measurement method for a distributed processing system.

[Means for solving problems]

The configuration of the present invention provides a response time measurement method for a distributed processing system that includes a host node including an input section and an output section, a terminal node at a terminal section, and a relay node between these host nodes and the terminal node. The node sends the measurement instruction from the input section to the end node, and this end node automatically creates an online measurement message and sends it back to the host node. When the relay node receives this online measurement message, it sends the next message. When the host node receives an online measurement message via this relay node, it sends it to the end node, and when the end node receives the online measurement message, it sends a measurement completion message to the host node. , and when the host node receives this measurement completion message, it outputs the measurement result to the output section.

In the configuration of the present invention, each node has the following functions.

(1) A function to send measurement instructions from the host node/input section to the end node.

・Receive online measurement messages from terminal nodes,
A function to send to the loop end node.

- A function that receives online measurement messages from end nodes and outputs measurement results to the output unit.

(2) A function that receives relay node online measurement messages and sends them to the relay node.

(3) A function that receives end node measurement instructions, automatically generates a measurement message, and sends it to the host node.

A function that receives measurement messages and sends them as measurement completion messages to the host node.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is an overall configuration diagram including one embodiment of the present invention.

The measurement system of this embodiment includes an instruction input section 1 such as a keyboard,
It is composed of a result output unit (recorder) 2, a host node 3, relay nodes 4 and 5, and a terminal node 6.

First, the terminal node 6, which is instructed by the input unit 1 to perform measurement from the host node 3, automatically generates an online measurement message and sends it to the host I/node 3. At that time, each relay node 4.5 sets the passage time in the measurement message and sends it to the next node.

The host node 3 that receives the online measurement message sets the arrival time to the host I node 3 and sends it back to the terminal node 6. Then relay node 4.5
Now, set the passage time in the measurement message and send it to the next node.

Next, the terminal node 6 that received the message for online measurement issues a measurement completion message and sends it to the host node 3.
Send to. The host node 3 that receives this measurement completion message edits and outputs the measurement results from the measurement result output unit 2 and ends the measurement.

〔Effect of the invention〕

As explained above, by implementing the present invention, the response time of each node is output individually, so the response time can be measured immediately, and the response time can also be quantitatively compared and analyzed. .
