Abstract

PURPOSE:To make versatile specification releasing for controlled source of information by determining beforehand number of calls for which specification releasing is possible corresponding to the source of information for each period in which data transfer control is removed. CONSTITUTION:A data transfer processing device 3 makes data transfer process between information sources 1-1-1-i and 2-1-2-j through transferring devices 4-1-4-k. A monitor controlling device 5 monitors the state of operation of the device 3 and the state of use of resources, and when congestion occurs, controls inflow of data from each information source. When congestion is released, the device 5 discriminates information source that makes porcessing of each transferring device at a fixed period, and checks whether number of calls for which specification is released in the period recorded in the controlling device corresponding to the information source in specification releasing controlling devices 6-1-6-i, 7-1-7-j arrives at the number of calls for which specification releasing is possible. When not arrived at, the device 5 releases specification for the transferring device and when arrived at, arranges to transfer through a device that has free scope and releases specification.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to a data transfer processing device, and more particularly to a restriction release method that allows flexible release of restrictions on calls whose data transfer is restricted.

(b) Prior Art and Problems FIG. 1 is a diagram showing an example of a conventional restriction release method in a data transfer processing device. In the first item 1, the data transfer processing device 3 includes a plurality of transfer devices 4-1 to 4-k, and accommodates information #'! l-1 to 1-i and 2-
1 to 2-j perform data transfer processing between them. For example, the call 111 issued by the information source i1 is connected to the information source 2-1 by the transfer device 4-1 as a call 211, and the information source i1 is connected to the information source i1 via the transfer device 4-1.
Data transfer processing is performed between 2 and 2-1. Similarly, there are calls 11m1 and 221 between information sources 1-1 and 2-2.
, and data transfer processing is performed via the transfer device 4-2, and data transfer processing is similarly performed between the information sources 1-1 and 2-3 via the calls 11m1 and 2jnj and the transfer device 4-k. will be held. The supervisory control device 5 monitors the operating status of the data transfer processing device 3 and the usage status of resources such as buffer memory, and transmits commands to each transfer device 4-1 to 4-1 when a clear state occurs. Then, the inflow of data from each information source 1-1 to 1-i and 2-1 to 2-j is restricted.When the clean state is reduced by 5'r%' due to the restriction of inflow of data, , the supervisory control device 5 transmits commands to each of the transfer devices 4 to 1 to 4-k, and transmits commands to each information source 1.
-1 to 1-i and 2-1 to 2-j are lifted. However, if all the transfer devices 4-1 to 4-k perform the restriction release process at the same time, there is a possibility that a conflict state will occur again, so a predetermined number of transfer devices 4-1 to 4-k 4-k is sequentially subjected to restriction release processing in a predetermined order.

As is clear from the above explanation (conventional regulations), (1) In the elimination method, when the clean state of the data transfer processing device 3 is released, the supervisory control device 5 and the restricted transfer device 4
-1 to 4-k are released for a predetermined number in a predetermined order at regular intervals. Therefore, transfer devices to be deregulated first (e.g. 4-1 and 4-2) are linked to specific information sources (e.g. 1-1).
If a number of calls (for example, 111 and 11m1) were being used intensively, there was a drawback that the process for releasing restrictions on other information sources would be delayed.

IcI Purpose of the Invention The purpose of the present invention is to eliminate the drawbacks of the conventional deregulation methods as described above, and to realize a deregulation method that performs deregulation processing with great flexibility for each information source subjected to restriction processing. is in

Cd) Structure of the Invention The purpose of this invention is to accommodate a plurality of information sources, regulate data transfer processing between the information sources according to system operating conditions and resource usage conditions, and send calls to a predetermined number of calls at regular intervals. This is achieved by predetermining in advance the number of calls that can be canceled within each period in correspondence with the information source in the data transfer processing device that cancels the restriction.

(el　Embodiments of the invention An embodiment of the present invention will be described below with reference to the drawings.

FIG. 2 is a diagram showing a restriction release method according to an embodiment of the present invention. Note that the same reference numerals refer to the same objects throughout the plan. In FIG. 2, restriction release control devices 6-1 to 6-i and 7-1 to 7-1 are installed in the data transfer processing device 3 for each information source 1-1 to 1-i and 2-1 to 2-j. ?
−j is provided. In addition, the supervisory control device 5 has the number of calls that can be canceled within one cycle set in advance for each information source 1-1 to 1-i and 2-1 to 2-j. The device 3 performs data transfer processing between the information sources 1-1 to 1-1 and 2-1 to 2-j stored in the same process as in FIG. 1, and the monitoring control device 5 is a data transfer processing device. The operating status and resource usage status of 3 are monitored, and if a clean state occurs, information is collected from each information source 1-1 to 1-i and 2-1 to 2-j in the same process as in Figure 1. restrict the inflow of data.

When the comparison state is canceled due to such data inflow restriction, the supervisory control device 5 detects whether the transfer device (for example, 4-1) that is the target of the restriction cancellation process is connected to the information source (for example, 1-1) that is performing the data transfer process. ), and determines whether the number of calls that have undergone deregulation within the cycle recorded in the deregulation control device 6-1 corresponding to the information source 1-1 has reached the number of calls that can be deregulated. Inspect and if it does not reach the transfer device 4-
1, and the restriction release control device 6-
1 is added to the deregulation-processed calls recorded in 1. The supervisory control device 5 then identifies the information source 1-1 for which the transfer device (for example, 4-2) that is the target of the deregulation process is performing the data transfer process, and selects the deregulation control device corresponding to the information source 11. It is checked whether the number of calls that have been processed for deregulation recorded in 6-1 has reached the number of calls that can be deregulated, and if the number has reached the number of calls that can be deregulated, the deregulation process for the transfer device 4-1 is not performed, Transfer device 4- to restriction release control device 6-1
Record number 2. The same process is executed for the transfer device 4-3 and below, and when the number of transfer devices that have undergone restriction release processing within the cycle reaches a predetermined number, the restriction release processing within the cycle is performed. Cancel each restriction release control device 6
-1 to 6-i and 7-1 to ? -Reset the number of calls that have been released from restrictions recorded in j. After the predetermined period has elapsed, the monitoring control device 5 activates the restriction release control devices 6-1 to 6-6.
-i and 7-1 to 7-j, and if it is detected that the number of the transfer device 4-2 is recorded in the restriction release control device 6-1, the transfer is performed. The restriction release process for the device 4-2 is executed, the number of the transfer device 4-2 recorded in the restriction release control device 6-l is deleted, and 1 is added to the number of calls that have undergone restriction release processing.

Thereafter, in the same process, the restriction cancellation process is executed for the transfer device whose number is recorded in the restriction cancellation control device 6-1, and the number of calls that have been processed for restriction cancellation recorded in the restriction cancellation control device 6-1 is When the number of calls that can be released from restriction is reached, or when there is no transfer device number recorded in the restriction release control device 6-1, similar restriction release processing is performed for the restriction release control device 6-2 and below. When the number of transfer devices that have undergone deregulation processing within the cycle reaches a predetermined number due to the deregulation process, the deregulation process within the cycle is stopped, and each deregulation control device 6-1 to 6-i and 7
-Reset the number of calls that have been released from restrictions recorded in -1 to 7-j. Furthermore, restriction release control devices 6-1 to 5-
If you have finished all the restriction release processing for the transfer devices whose numbers are recorded in i and 7-1 to 7-j, and the number of transfer devices that have undergone restriction release processing does not reach the predetermined number, proceed to the next step. Then, the restriction cancellation process is restarted from the transfer device that is the target of the restriction cancellation process using the above-mentioned process.

As is clear from the above description, according to this embodiment, the monitoring and control device 5 monitors the information sources 1-1 to 1 within each cycle of deregulation.
-1 and 2-1 to 2-j, the number of calls that can be canceled is not processed for more than the predetermined number of calls that can be canceled, so the number of calls that can be canceled is concentrated on a specific transfer device (for example, 4-1). ,
Delays in the restriction release processing of other transfer devices are prevented.

Note that FIG. 2 is merely one embodiment of the present invention, and the configuration of the data transfer processing device 3, for example, is not limited to that shown in the figure, and many other modifications may be considered; Even in this case, the effects of the present invention remain the same. Furthermore, by setting the number of calls that can be canceled within one cycle for each information source uniformly for all information sources, it is also possible to perform the same restriction cancellation process for each information source, and also to Although it is also possible to give priority to the deregulation of each information source by individually setting the number for each information source, the effect of the present invention remains unchanged in either case.

(fl) Effects of the Invention As described above, according to the present invention, in the data transfer processing device, it becomes possible to perform restriction release processing with great flexibility for each information source.
