Description

How to limit the execution speed of switch commands

technical field

The invention relates to a method for limiting the command execution speed of a switch.

Background technique

The management module of the switch system is responsible for processing the commands input by the user and then analyzing them. After obtaining the command information, if the command is correct, it will be sent to the business module corresponding to the command, and then the business module will perform business processing. After the business module is processed, it will respond to the management module according to the processing result. Correctly executed commands will receive correct responses from the management module.

As shown in Figure 1, the execution of the command needs to be sent twice, and the process of waiting for the response to be received twice. That is: 1. The user enters a command, and then waits for the response from the management module; 2. The management module receives the command and processes it and sends it to the business module, and then waits for the business module to execute and receive the response; 3. The business module responds to the management module after receiving the command and processing it , and finally the management module responds to the user.

Now, a common problem is that users input commands frequently, and before the business module returns a response, they quickly issue the second and a large number of subsequent commands, which causes serious congestion in the communication between the management module and the business module. And the overloaded operation of the business module will eventually affect the operation of other business programs, which will seriously cause the program of the switch system to be disordered or even crash.

Contents of the invention

The technical problem to be solved by the present invention is to provide a method for alleviating the pressure of the switch system and limiting the execution speed of switch commands.

In order to solve the above-mentioned technical problems, the present invention designs a method for limiting the command execution speed of the switch, comprising the following steps: setting the critical value of the command execution speed of the switch; calculating the current speed of the command execution of the switch; judging whether the current speed exceeds the Critical value, if yes, the switch system management module stops sending commands to the service module, if not, the switch system management module continues to send commands to the service module.

As a further improvement of the present invention, the method for limiting the execution speed of the switch command further includes a step of feeding back to the user that the current speed exceeds the critical value.

As a further improvement of the present invention, if the current speed exceeds the critical value, the switch system management module also makes a return processing operation.

As a further improvement of the present invention, the step of calculating the current speed of the switch to execute the command includes the following steps: use the counter to count the management module to receive the command, and obtain the value of the received command; obtain the system clock of the switch system; repeat the above two steps , Subtract the old system clock from the new system clock to calculate the time-consuming, subtract the value of the old received command from the value of the new received command, calculate the difference between the values of the commands received during the time-consuming process, and then The current speed at which the switch executes the command is calculated by using the difference between the numerical values of the commands received during the time-consuming process and the time-consuming process.

As a further improvement of the present invention, the critical value is set on the command line of the user configuration interface of the switch.

The invention sets the critical value of the command execution speed of the switch, that is, the upper limit of the command execution speed of the switch system. If the command speed received by the management module exceeds the critical value, it will stop sending commands to the business module for processing, so as to relieve the pressure on the system and avoid serious situations such as damage to the switch system, machine jams, program error jumps, and crashes.

Detailed ways

In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments It is only a part of the embodiments of the present invention, but not all of them.

The invention provides a method for limiting the command execution speed of the switch, which is used to limit the situation that the business modules of the switch system are overloaded to process commands. Protect the system of the switch to the greatest extent from being damaged, avoid serious problems such as machine jams, program error jumps, and crashes, and ensure the safe operation of the switch.

As shown in Figure 2, the method for limiting the command execution speed of the switch in this embodiment includes the following steps:

Step 1: The step of setting the critical value of the command execution speed of the switch. Setting the critical value is performed in the command line of the user configuration interface of the switch, so as to provide the user with a command interface. The critical value can be set according to the different processing capabilities of the switch into different values.

Step 2: Calculate the current speed at which the switch executes the command. In this embodiment, the method for calculating the current speed at which the switch executes the command includes: first using the counter to count the management module to receive the command, and obtain the numerical value of the received command; then obtain the system clock (tich number) of the switch system; repeat the above two steps The step is to obtain two sets of data, the value of the old command received and the value of the new command received, the old system clock and the new system clock, subtract the old system clock from the new system clock, convert the time consumption, and use Subtract the value of the new received command from the value of the old received command to convert the value difference of the command received during the time-consuming process, and then use the value difference of the command received during the time-consuming process and the time-consuming to calculate the switch The current speed at which the command is executed. The counter of the present invention obtains the value of the command received and the system clock (tich number) obtained by the switch system has been repeating the cycle, and the above-mentioned two groups of old and new data are also updated in real time. Therefore, the calculated current speed of the switch to execute the command is also constant. Keep updating.

Step 3: After obtaining the current speed at which the switch executes the command, it can be judged whether the current speed exceeds the critical value, if so, the switch system management module stops sending commands to the service module, and performs a return operation, so that the service module can Reduce the burden; if not, the switch system management module continues to send commands to the service module, that is, the current speed at which the switch executes the command does not exceed the critical value, which proves that the service module is still within the capacity of being able to handle the command. Therefore, according to In a normal procedure, the switch system management module will send the command to the service module, and the service module will execute the processing.

In this embodiment, when the current speed at which the switch executes commands exceeds the critical value, the management module will also feed back this situation to the user to serve as an early warning. After the user is informed, the input of the command can be suspended or delayed.

Using the method of the present invention to limit the command execution speed of the switch, the execution process of the command is: first, the user inputs the command on the switch, the command is received by the management module, if the current speed exceeds the critical value, the management module returns and stops sending commands to the service module , so as to relieve the pressure on the business module, and at the same time, the management module will also respond to this situation to the user to let the user know the situation. If the current speed does not exceed the critical value, the management module sends a command to the business module according to the normal procedure, the business module receives the command and performs processing, and then responds to the management module according to the processing result, and the management module then responds to the user.

The above only expresses one embodiment of the present invention, and its description is relatively specific and detailed, but it should not be construed as limiting the patent scope of the present invention. It should be pointed out that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent for the present invention should be based on the appended claims.
