[0002] A switch is a device that completes information exchange functions in a communication system and is used for the forwarding of electrical signals. With the intensification of industrial informatization and intelligence, switches are required in more and more scenarios.

[0003] When the current switch performs information exchange, all requests are simultaneously subjected to information exchange.

[0005] To achieve the above purpose, the present invention provides the following technical solutions: A data reading and writing method for a switch, the method comprising: Receiving all reading and writing requests, determining whether the source device of the reading and writing request is in the trusted device list. If the determination fails, manual review is performed on the source device. If the manual review fails, the reading and writing request is discarded. After the manual review passes, the source device is also added to the trusted device list. If the determination passes, the reading and writing request is parsed to obtain the target data of the reading and writing request; Determining the execution time of the reading and writing request based on the target data, comparing the execution time with a preset threshold to obtain reading and writing requests with different priorities; Parsing the data type of the source device of the reading and writing request, and converting the type of the target data into the data type of the source device of the reading and writing request; Based on the priority of the reading and writing request, determining the execution result of each reading and writing request.

[0006] As a further solution of the present invention: the step of determining the execution time of the reading and writing request based on the target data, comparing the execution time with a preset threshold to obtain reading and writing requests with different priorities includes: Dividing the target data into different sub-data segments, determining the execution duration of each sub-data segment, and the sum of the execution durations of all sub-data segments is the execution time of the reading and writing request; Comparing the execution time of the reading and writing request with the preset threshold. The reading and writing request with an execution time less than the preset threshold is a first-priority reading and writing request, and the reading and writing request with an execution time greater than or equal to the preset threshold is a second-priority reading and writing request; Sorting the reading and writing requests with the same priority to obtain the execution queue of the reading and writing requests with the same priority.

If the judgment result is that the two are inconsistent, convert the type of the target data into the data type of the read-write request source device. If the judgment result is that the two are consistent, there is no need to change the type of the target data.

[0009] As a further solution of the present invention, the step of determining the execution result of each read-write request based on the priority of the read-write request includes: Execute the execution queue of the first priority and the execution queue of the second priority in sequence, and write the execution queue into the buffer disk in the order from front to back; Write the data in the buffer disk into the source device of the read-write request in sequence.

[0010] The technical solution of the present invention also provides a data read-write system for a switch, and the system includes: An analysis module, configured to receive all read-write requests, judge whether the source device of the read-write request is in the trusted device list. If the judgment fails, perform manual review on the source device. If the manual review fails, discard the read-write request. After the manual review passes, the source device is also added to the trusted device list.

[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clear and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0027] Embodiment 1: Figure 1 It is a flowchart of the data reading and writing method for a switch. In an embodiment of the present invention, a data reading and writing method for a switch, the method includes: Receiving all read - write requests, judging whether the source device of the read - write request is in the trusted device list. If the judgment fails, manual verification is performed on the source device. If the manual verification fails, the read - write request is discarded. After the manual verification passes, the source device is also added to the trusted device list. If the judgment passes, the read - write request is parsed to obtain the target data of the read - write request; The switch will receive read and write requests from many devices at the same time. It is necessary to screen these read and write requests and trace the source devices of the read and write requests. Each source device has its own unique identification number. The database will store a pre-listed trusted device list, and the trusted device list stores the identification numbers of trusted devices. Compare the identification number of the source device of the read and write request with the identification numbers in the trusted device list to check whether the identification number of the source device is in the trusted device list. If the identification number of the source device is in the trusted device list, it means that the source device is a trusted device, and directly parse the read and write request of the trusted device to query which are the target data of the read and write request of the trusted device. If the identification number of the source device is not in the trusted device list, intercept the read and write request of the source device. The administrator judges whether the source device belongs to a trusted device. If the administrator judges that the source device does not belong to a trusted device, directly discard the read and write request. If the administrator judges that the source device belongs to a trusted device, the judgment passes, parse the read and write request of the source device, and add the source device to the trusted device list. The next read and write request of the source device can pass directly.

[0028] Determine the execution time of the read and write request based on the target data, compare the execution time with a preset threshold to obtain read and write requests with different priorities; Know the target data corresponding to the read and write request. Based on the current channel occupancy, the duration required to execute the read and write request can be calculated. This duration is the execution time of the read and write request. In order to distinguish the order of execution of read and write requests, a time threshold is preset. Compare the execution time of the read and write request with this time threshold to obtain the priority of the execution of the read and write request.

[0029] Parse the data type of the source device of the read and write request and convert the type of the target data to the data type of the source device of the read and write request; The format of storing data in each source device is fixed. Knowing the model of the source device can know all the formats of storing data in the source device. Then confirm the type of the target data of the read and write request of the source device and check whether the format of the target data is included in all the formats of storing data in the source device. If the format of the target data is included in all the formats of storing data in the source device, it means that the target data can be directly mapped in the source device. If the format of the target data is not included in all the formats of storing data in the source device, it is necessary to convert the format of the target data into a format that can be stored in the source device to facilitate subsequent direct storage into the source device and reduce the time required for subsequent execution.

[0030] Based on the priority of the read and write request, determine the execution results of each read and write request.

[0031] Determining the priorities of each read / write request determines the order of execution of each read / write request. Each read / write request is executed in the determined order until the last read / write request is executed, and it is confirmed that all read / write requests have been executed.

[0032] Figure 2 It is the second sub-process block diagram of the data read / write method of the switch. In the embodiments of the present invention, the steps of determining the execution time of the read / write request based on the target data and comparing the execution time with a preset threshold to obtain read / write requests with different priorities include: Divide the target data into different sub-data segments, determine the execution duration of each sub-data segment, and the sum of the execution durations of all sub-data segments is the execution time of the read / write request; According to a preset rule (this rule can be classified according to different data types or according to the length of the data), divide the target data into multiple sub-data segments, calculate the time for executing each sub-data segment, obtain the execution duration of each sub-data segment, and add up the execution durations of all sub-data segments in the same target data to obtain the execution time of the target data, which is the execution time of the corresponding read / write request.

[0033] Compare the execution time of the read / write request with the preset threshold. The read / write request with an execution time less than the preset threshold is a first-priority read / write request, and the read / write request with an execution time greater than or equal to the preset threshold is a second-priority read / write request; There is a preset threshold for the execution time. A read / write request with an execution time equal to or exceeding this threshold indicates that the execution time is too long and the priority of this read / write request is low. A read / write request with an execution time less than this threshold indicates that the execution time is short and the priority of this read / write request is high.

[0034] Sort the read / write requests with the same priority to obtain the execution queue of the read / write requests with the same priority.

[0035] Read / write requests with the same priority also need to be sorted to determine the order of execution of all read / write requests. The read / write request to be executed first is in the front, and the read / write request to be executed later is in the back. The read / write requests with the same priority form a specific execution queue.

[0036] The steps of sorting the read / write requests with the same priority to obtain the execution queue of the read / write requests with the same priority include: Confirm the execution time of each read / write request among the read / write requests with the same priority; Correspond the read / write requests with the same priority to their respective execution times, and the execution time of each read / write request can be known; Compare the execution times of each read / write request in pairs, and the one with the shorter execution time is in the front row to obtain the execution queue.

[0037] By comparing the execution time of each read / write request with the execution times of the remaining read / write requests in sequence, the length order of the execution times of all read / write requests in the same priority level can be obtained. By arranging the read / write requests in the same priority level in ascending order of execution time, the execution queue of the read / write requests is formed.

[0038] Figure 3 It is the third sub-process block diagram of the data read / write method of the switch. The steps of parsing the data type of the read / write request source device and converting the type of the target data into the data type of the read / write request source device include: Parse the data type of the read / write request source device and confirm the type of the target data; All types of data cannot be stored in the source device. It can only store a fixed number of formats. Data in other formats need to be format-converted before they can be stored in the source device. Therefore, it is necessary to confirm the data format of the source device and also the format of the target data corresponding to this read / write request.

[0039] Judge whether the type of the target data is consistent with the data type of the read / write request source device. If the judgment result is that the two are inconsistent, convert the type of the target data into the data type of the read / write request source device. If the judgment result is that the two are consistent, there is no need to change the type of the target data.

[0040] Check whether the format of the target data is consistent with the data format of the source device. If the two are consistent, the target data can be directly stored in the read / write request source device; if the two are inconsistent, the format of the target data needs to be converted into a format that can be stored in the read / write request source device, and then the converted target data can be stored in the source device to implement the read / write operation.

[0041] Figure 4 It is the fourth sub-process block diagram of the data read / write method of the switch. The steps of determining the execution results of each read / write request based on the priority of the read / write request include: Execute the execution queue of the first priority level and the execution queue of the second priority level in sequence. The execution queue is written into the buffer disk in the order from front to back; The read / write requests in the same priority level form the execution queue of the read / write requests at this priority level. The target data of each read / write request can be obtained. First, execute the execution queue of the first priority level, write the corresponding target data into the buffer disk in sequence and sort them in the order of precedence to avoid blocking the current channel. After executing the execution queue of the first priority level, then execute the execution queue of the second priority level, and the process is the same as above.

[0042] Write the data in the buffer disk into the read / write request source device in sequence.

[0043] At this time, the buffer disk contains the target data of all read / write requests, and these target data are arranged in the order of the read / write requests. Just write the target data into the corresponding source device of the read / write request in sequence to complete the execution of the read / write request.

The data reading and writing system of the switch according to claim 7, characterized in that: The sorting unit comprises: A confirmation unit, used to confirm the execution time of each read / write request in the read / write request of the same priority; The queue generation unit is used to compare the execution time of each read and write request in pairs, and the ones with shorter execution time are placed in the front row to obtain the execution queue.

9. The data reading and writing system of the switch according to claim 6, characterized in that: The parsing module comprises: A parsing unit, used to parse the data type of the source device of the read / write request and confirm the type of the target data; The judgment unit is used to judge whether the type of the target data is consistent with the data type of the read / write request source device. If the judgment result is that the two are inconsistent, the type of the target data is converted to the data type of the read / write request source device. If the judgment result is that the two are consistent, there is no need to change the type of the target data.

10. The data reading and writing system of the switch according to claim 8, characterized in that: The execution module includes: A first writing unit is used to sequentially execute the execution queue of the first priority and the execution queue of the second priority, and the execution queues are sequentially written into the buffer disk in a front-to-back order; The second writing unit is used to write the data in the buffer disk into the source device of the read / write request in sequence.
