Abstract

PURPOSE:To shorten the time required for data update of a terminal equipment by sending only a discording data group at the time of sending data groups required for network state display from a main processor to the terminal equipment. CONSTITUTION:When a request of network state display is inputted to a terminal equipment 4, the terminal equipment 4 divides data for network state display held in itself into plural data groups and subjects each of these data groups to preliminarily determined operation and sends an obtained code for confirmation to a main processor 3 as a data group collective gathering request signal with check sum. When receiving this signal, the main processor 3 divides data for network state display held in itself into plural data groups to perform the check sum calculation and collates results in 1:1 to detect coincidence or disaccord of each data group and selects only disaccording data groups to send them to the terminal equipment 4. The terminal equipment 4 receives these new data groups to update data for network state display held in itself. Thus, the time required for data update of the terminal equipment is shortened.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a communication control method for a network management system, and particularly to collation of a group of data necessary for a terminal device to display the network status of a data exchange network. This invention relates to a communication control method for a network management system to collect missing information.

[Conventional technology]

As shown in the flowchart of conventional data collection operations in Figure 3, the communication control method of conventional network management systems allows terminal devices to display the same network status as the main processing unit, for the purpose of speeding up network status display. In order to perform control such that the data group necessary for
At step 02, a request signal 307 requesting bulk collection of data groups is sent to the main processing device, and upon receiving the request signal 307 at step 8303, the main processing device sends out all the necessary data groups as a response data signal 308 at step 5304. The terminal device that received all the necessary data groups in 5305 updated all the data in 5306.

[Problem to be solved by the invention]

In the communication control method of the conventional network management system described above, when a terminal device collectively collects a group of data necessary for displaying the network status, the main processing unit sends all the data group to the terminal device, There is a problem that the required data group is large and the communication speed of the terminal device is generally low, so the time required for batch collection is long.

It is an object of the present invention, when a main processing unit sends a data group necessary for displaying the network status to a terminal device, to inform each of a plurality of data groups in advance of the discrepancy status of all data held by both parties at this point. Communication control for a network management system that can shorten the time required to update data on terminal devices by knowing by comparing confirmation codes obtained by performing predetermined calculations and sending out only unmatched data groups. The purpose is to provide a method.

[Means to solve the problem]

The communication control method of the network management system of the present invention includes a main processing unit whose main functions are data control and analysis, a plurality of terminal devices whose main functions are user interface processing, and a display function that displays status on a display. In a communication control system for a network management system that manages a data exchange network, the terminal device divides network status display data held by itself into a plurality of data groups before displaying the network status of the data exchange network. A confirmation code sending function that sends a confirmation code obtained by performing a predetermined operation on each of the plurality of data groups to the main processing device, and a confirmation code sending function corresponding to the plurality of data groups sent from the main processing device. the main processing unit has an update function of receiving a data group and updating the network status display data held by the main processing unit, and the main processing unit sends the confirmation code corresponding to the plurality of data groups sent by the terminal device. A verification function that compares the contents of the latest network status display data received and held by the self, and a data group that detects a discrepancy as a result of the verification is checked from the latest network status display data held by the self. This configuration has a sending function that sends only a data group corresponding to the detected data group to the terminal device.

〔Example〕

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

FIG. 1 is a block diagram of one embodiment of the present invention.

A network management system that manages a data exchange network composed of a data exchange device 1 and a line group 2 includes a main processing device 3 whose main functions are data control and analysis, and a display screen whose main function is user interface processing. It is composed of a plurality of terminal devices 4 having a display function for displaying the status, each having a communication line 5, and a communication path 6 is set for sending and receiving data directly or via a data exchange network, so that mutual communication is possible. Is going.

Next, a data group update operation according to an embodiment of the present invention will be explained.

FIG. 2 is a flowchart of a data group update operation according to an embodiment of the present invention.

When a request for network status display is input to the terminal device, 5101
will accept the occurrence of this data bulk collection factor. Next, in step 5102, the terminal device divides the network status display data it holds into multiple data groups, and performs a predetermined operation (hereinafter referred to as checksum calculation) on each of the multiple data groups. , 8103, check the confirmation code obtained in this way and send the data group with sum - bulk collection request signal 1
10 to the main processing unit. In 5104, the main processing unit receives the check-sum data group-bulk collection request signal 110, and in 5105 divides the network status display data held by itself into a plurality of data groups, and collects the check-sum data in the same way as the terminal device. Perform calculations and compare the results 1:1 with 8106
In the verification step 17, a state of coincidence or mismatch is detected for each data group. Next, in step 8107, only each data group with a checksum mismatch detected in the previous stage is selected and sent as a response data signal 111 to the terminal device. The terminal device that received only each data group with a checksum mismatch in 8108 receives 5109
Then, this new data group is used to update only the old network state display data held by itself.

〔Effect of the invention〕

As explained above, when the main processing unit sends a data group necessary for displaying the network status to the terminal device, the present invention allows the discrepancy status of all the data held by both parties at this time to be sent to a plurality of data groups. By performing predetermined calculations on each of the data and comparing the confirmation codes obtained, and by transmitting only the data groups that do not match, the time required to update data on the terminal device can be reduced. Yes.
