α1 is a device management task that manages the entire device.

Next, the operation will be explained.

Data from the terminal line passes through the line control task (6), data transfer task (7), and bus control task (9) of the terminal line support unit (1), and is transferred to the relay line support unit via the external bus (4). (2) is multiplexed. Multiplexed data.

After passing through the bus control task (9), the data transfer task (7), and the line control task (6) of the trunk line support unit (2), it is sent onto the trunk line.

Data from the trunk line is passed through the line control task (6) of the trunk line support unit (2) and then to the data transfer task (power).In the data transfer task (7), the terminal line support unit (f)
The allocation to il is processed and passed to the bus control task (9). Each terminal line corresponding section (1) is connected via an external bus (4).
) is sent out onto the terminal line via the bus control task (9), data transfer task (7), and two line control tasks (6) of the terminal line correspondence section (1).

Simultaneously with the above transfer operation, the traffic control task (8) of the terminal line support unit C1) and the trunk line support unit (2) operates to monitor the traffic, and when the traffic exceeds a certain amount, the traffic control task (8) is activated for each line. take measures such as input regulation to suppress excessive traffic.

[Problem to be solved by the invention] Since the conventional multiplexing device is configured as described above,
In order to multiplex the traffic of multiple terminal line corresponding parts onto the traffic of one trunk line corresponding part, in general, the relay u
The processing capacity of the line handling section is more important than that of the terminal line handling section.

Therefore, improving the throughput of the terminal line corresponding section leads to improving the throughput of the device.

In conventional traffic control, the terminal line support unit monitors the traffic volume in parallel with data transfer.
There was a problem in that the throughput of the terminal line corresponding section was reduced.

This invention was made to solve the above-mentioned problems, and the object is to obtain a traffic control method that can control the amount of traffic of a multiplexing device without reducing the throughput of the terminal line corresponding section. .

[Means to solve the problem]

The traffic control method according to the present invention analyzes the traffic amount of the trunk line corresponding section.

It grasps the amount of traffic occurring in each terminal line corresponding section and performs traffic control based on that information.

[Effect]

The traffic control method according to the present invention eliminates the need for traffic volume monitoring processing in each terminal line corresponding section by controlling the traffic of each terminal line corresponding section based on the traffic information of the trunk line corresponding section. , the throughput of the device is improved.

〔Example〕

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

The configuration of the multiplexing device in this invention is similar to that of the prior art.

FIG. 1 shows an example of a software configuration diagram.

In the figure, (6) is the line control task, (7) is the data transfer task, (8) is the traffic control task, (9) is the bus control task, α1 is the device management task, and αυ is the trunk line support unit (2). This is a traffic management task that monitors the traffic amount and controls the traffic of the entire device.

FIG. 2 is an embodiment of a flowchart for realizing the present invention. Figure 2 (a) shows the traffic management task α
υ, FIG. 2 (1)) is a schematic flow chart of the traffic control task (8) of each line corresponding section, and FIG. 2 (C) is a schematic flow chart of the traffic control task (8) of the trunk line corresponding section (2). 2 is a schematic flowchart of a periodic activation routine.

Next, the operation will be explained. Note that the data transfer operation is the same as in the prior art.

Here, only the traffic control operation will be explained.

At the time of data transfer, the traffic control task (8) of the trunk line support section (2) is activated periodically and reports its own traffic information to the device management section (3).

The traffic management task αD of the device management section (3) analyzes the traffic information of the trunk line correspondence section (2), determines the amount of traffic occurring on each terminal line correspondence section +1),
When this value exceeds a certain amount, each terminal line support section (
1) and the traffic control task (2) of the trunk line support unit (2).
8) issues an input restriction instruction to suppress the traffic flowing in from the line.

The system will continue to analyze traffic information and issue an instruction to cancel input restrictions when the amount of traffic falls below a certain level.

The traffic control task (8) of each line corresponding unit +1) and (2) performs input regulation and release of regulation according to instructions from the traffic management task return.

The process will be explained below according to the flowchart.

The traffic management task αρ is a periodically activated task, and collects and analyzes traffic information of the trunk line corresponding section (2). As a result of the analysis, if the amount of traffic exceeds a certain amount (hereinafter referred to as ＼＠), input restriction instructions are sent to each line corresponding section (11
, (2).

If the width edge is not detected, determine whether or not input is currently being restricted, and if so, check.

An instruction to cancel the input restriction is sent to each line corresponding section +11 and +21. If it is not regulated, do nothing.

The traffic management task Qυ periodically executes the above operations.

The traffic control task (8) is activated at the timing of receiving an instruction from the traffic management task aυ, and checks the content of the traffic control instruction.

Perform input restrictions or release restrictions.

There is a periodic activation routine in the traffic control task (8) of the trunk line support unit (2), which periodically reports its own traffic information to the traffic management task αυ.

〔Effect of the invention〕

As described above, according to the present invention, the track amount of each terminal line corresponding section is determined based on the information from the trunk line corresponding section, and the traffic of the entire device is controlled based on this information. As for the line support department.

It is only necessary to execute traffic control when there is an input restriction instruction or a restriction release instruction.1 Since there is no need for traffic control operation during normal data transfer, there is an effect that the through-top is improved.
