Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.
[0023] To facilitate understanding of this embodiment, the embodiments of the present application are described in detail below.
[0024] The present application embodiment provides an address port self-learning method, which is applied to a data exchange device, such as Figure 1 As shown, Figure 1 A flowchart of an address port self-learning method provided in an embodiment of the present application. The method comprises the following steps: S101, the data exchange device 200 receives service data sent by a first terminal device. Specifically, Figure 2 As shown, Figure 2 A schematic diagram of a connection method between a data exchange device 200 provided in an embodiment of the present application and a first terminal device and a second terminal device. The type of the first terminal device includes at least one of the following: a first serial port device 300, a first network device 400, and a first optical fiber device 500. If the first terminal device is the first serial port device 300, the service data is serial port service data; if the first terminal device is the first network device 400, the service data is network service data; if the first terminal device is the first optical fiber device 500, the service data is optical fiber service data. The data exchange device 200 can support the connection of different types of first terminal devices, and support receiving different types of service data and processing different types of service data.
[0025] S102: The data exchange device parses the service data to obtain a service data frame.
[0026] The service data frame includes: a source address, a destination address and a data port number corresponding to the source address.
[0027] Specifically, the data exchange device 200 parses the service data into service data frames so as to forward the service data according to the service data frames. Take the first terminal device (first serial port device 300) as an example for introduction. The address of the first terminal device (first serial port device 300) is 0001, the port number of the data exchange device 200 to which the first terminal device (first serial port device 300) is connected is 01, the first terminal device (first serial port device 300) wants to send service data to the second terminal device (second serial port device 301), and the address of the second terminal device (second serial port device 301) is 0010. After receiving the serial port service data, the data exchange device 200 parses the serial port service data to obtain a serial port service data frame. The serial port service data frame includes a source address 0001 and a destination address 0010. The data port number corresponding to the source address 0001 is 01. Among them, the second terminal device also includes a second optical fiber device 501 and a second network device 401, which will not be repeated here.
[0028] S103, the data exchange device determines whether there is a historical address identical to the destination address in the mapping table, if so, execute step S109, if not, execute step S104.
[0029] Specifically, a mapping table is stored in the data exchange device 200, and a plurality of historical addresses are stored in the mapping table. The network service data mapping table is taken as an example for introduction. As shown in Table 1, Table 1 is a network service data mapping table.
[0030] Table 1: Table address Flag bit (1 bit) Historical address (48 bits) Data port number (8 bits) 0 1 123456781111 01 1 1 123456782222 02 2 0 000000000000 00 The table entry address in the network service data mapping table is used to characterize the order in which the historical addresses are stored in the network service data mapping table. The data exchange device 200 parses the network service data sent by the first network device 400 to obtain a network service data frame. If the destination address in the network service data frame is 123456781111 or 123456782222, it means that there is a historical address in the network service data mapping table that is the same as the destination address in the network service data frame. At this time, step S109 will be executed, that is, the data exchange device 200 encapsulates the network service data frame to obtain network service data, and sends the network service data to the second terminal device (second network device 401) corresponding to the destination address (123456781111 or 123456782222).
[0031] If the destination address in the network service data frame is different from 123456781111 and 123456782222, it means that there is no historical address in the network service data mapping table that is the same as the destination address in the network service data frame. In this case, step S104 is executed.
[0032] As can be seen from the above, the data exchange device 200 can accurately determine the second terminal device to which the service data needs to be sent according to the mapping table.
[0033] S104, the data exchange device determines whether the first mapping relationship and the second mapping relationship are the same, if so, execute step S106, if not, execute step S105.
[0034] The first mapping relationship is a mapping relationship between a source address and a data port number, and the second mapping relationship is a mapping relationship between each historical address recorded in the mapping table and a historical data port number corresponding to each historical address.
[0035] Specifically, the mapping relationship between the source address and the data port number in the network service data frame is taken as an example for introduction. The data exchange device 200 parses the network service data sent by the first network device 400 to obtain a network service data frame. If the mapping relationship between the source address and the data port number in the network service data frame is 123456781111-01 or 123456782222-02, it means that the first mapping relationship is the same as the second mapping relationship. At this time, step S106 will be executed, that is, the data exchange device 200 encapsulates the network service data frame to obtain network service data, and broadcasts the network service data to the first terminal device (the first network device 400) and the second terminal device (the second network device 401).
[0036] S105: The data exchange device updates the source address and the data port number corresponding to the source address into a mapping table.
[0037] Specifically, the source address and the data port number corresponding to the source address are used as an example for introduction. If the mapping relationship between the source address and the data port number is 123456783333-03, it means that the first mapping relationship is different from the second mapping relationship, and 123456783333-03 will be recorded in the above Table 1.
[0038] With such a configuration, if the second terminal device (second network device 401) sends new network service data to the first terminal device (first network device 400), the source address 123456783333 is the destination address of the new network service data. Since the mapping relationship 123456783333-03 between the source address and the data port number has been updated in the network service data mapping table, the data exchange device 200 can directly send the new network service data to the first terminal device (first network device 400) according to the mapping relationship 123456783333-03 between the source address and the data port number, without repeatedly updating the second mapping relationship in the network service data mapping table.
[0039] S106: The data exchange device encapsulates the service data frame to obtain service data, and broadcasts the service data to the first terminal device and the second terminal device.
[0040] Specifically, if there is no historical address in the network service data mapping table that is the same as the destination address in the network service data frame, the data port number corresponding to the destination address cannot be determined, and thus the data exchange device 200 cannot forward the service data to the second terminal device connected to the data port number corresponding to the destination address. At this time, the data exchange device 200 will send the service data to both the first terminal device and the second terminal device. With this configuration, the second terminal device connected to the data port number corresponding to the destination address will definitely receive the service data so as to return feedback information to the data exchange device 200.
[0041] S107: The data exchange device receives feedback information returned by the second terminal device corresponding to the destination address.
[0042] The feedback information includes the data port number to which the second terminal device corresponding to the destination address is connected and the address of the second terminal device corresponding to the destination address.
[0043] Specifically, the broadcasting of network service data is taken as an example for introduction. The data exchange device 200 broadcasts the network service data to the first terminal device (first network device 400) and the second terminal device (second network device 401). When the second terminal device (second network device 401) receives the network service data, the data port number of the second terminal device connected corresponding to the destination address in the network service data and the address of the second terminal device corresponding to the destination address are fed back to the data exchange device 200, so that the data exchange device 200 updates the network service data mapping table according to the feedback information.
[0044] S108: The data exchange device updates the data port number to which the second terminal device corresponding to the destination address is connected and the address of the second terminal device corresponding to the destination address into the mapping table according to the feedback information.
[0045] Specifically, take network service data as an example. If the destination address of the network service data is 123456784444 and the corresponding data port number of the second terminal device is 04, the feedback information includes 123456784444-04. The data exchange device 200 stores 123456784444-04 in the network service data mapping table.
[0046] With such a configuration, if the first terminal device (first network device 400) sends new network service data to the second terminal device (second network device 401), since the data port number 04 to which the second terminal device (second network device 401) corresponding to the above-mentioned destination address 123456784444 is connected and the address 123456784444 of the second terminal device (second network device 401) corresponding to the destination address 123456784444 have been updated in the network service data mapping table, the data exchange device 200 can directly send the new network service data to the second terminal device (second network device 401) according to the mapping relationship 123456784444-04 between the destination address and the data port number, without the need to repeatedly update the network service data mapping table.
[0047] S109, the data exchange device encapsulates the service data frame to obtain service data, and sends the service data to the second terminal device corresponding to the destination address.
[0048] Specifically, since the data exchange device 200 determines that there is a historical address identical to the destination address in the mapping table, the data exchange device 200 can accurately determine the data port number to which the second terminal device corresponding to the destination address is connected, and can then accurately send service data to the second terminal device connected to the data port number.
[0049] The embodiment of the present application provides an address port self-learning method, in which if the first mapping relationship and the second mapping relationship are not the same, the data exchange device 200 updates the source address and the data port number corresponding to the source address into the mapping table, and if the first mapping relationship and the second mapping relationship are not the same, the data port number of the second terminal device connected to the destination address and the address of the second terminal device corresponding to the destination address are updated into the mapping table according to the feedback information. In the prior art, the connection relationship between the first terminal device and the data port is fixed, and the connection relationship between the second terminal device and the data port is also fixed. When the first terminal device and / or the second terminal device is replaced, it is necessary to manually reset the connection relationship between each data port number in the mapping table and the first terminal device or the second terminal device in order to accurately determine the transmission path of the business data. Compared with the prior art, this method can automatically update the mapping table, save time and manpower, and improve the updating efficiency of the transmission path of the business data.
[0050] The following describes how the data exchange device 200 sends service data to the second terminal device corresponding to the destination address. The data exchange device 200 extracts information from the service data frame, obtains a mapping relationship between the destination address and the data port number, and sends the service data to the second terminal device according to the mapping relationship between the destination address and the data port number.
[0051] Specifically, the above-mentioned network service data is taken as an example for introduction. The network service data frame is obtained by parsing the network service data by the data exchange device 200. Information is extracted from the network service data frame, and the mapping relationship between the destination address and the data port number is 123456784444-04. It can be seen that the address (destination address) of the second terminal device (second network device 401) to which the network service data is to be sent is 123456784444, and the data port number to which the second terminal device (second network device 401) is connected is 04. Therefore, the data exchange device 200 sends the network service data to the second terminal device (second network device 401) with an address of 123456784444.
[0052] In this manner, the data exchange device 200 determines the transmission path of the service data according to the mapping relationship between the destination address of the service data and the data port number, thereby improving the transmission accuracy and efficiency of the service data.
[0053] In one embodiment, if Figure 3 As shown, Figure 3 The data exchange device 200 provided in the embodiment of the present application is a structural diagram. The data exchange device 200 includes: a storage module 201 and an address port self-learning module 202; the address port self-learning module 202 sends a table lookup instruction to the storage module 201, sends a mapping table to the address port self-learning module 202 according to the table lookup instruction, reads the mapping table, and obtains a second mapping relationship.
[0054] Specifically, the above mapping table is stored in the storage module 201, and the storage module 201 has a data reading function. When the storage module 201 reads the table lookup instruction, the mapping table is sent to the address port self-learning module 202 according to the table lookup instruction. The address port self-learning module 202 also has a data reading function. The address port self-learning module 202 reads the mapping table to obtain a second mapping relationship.
[0055] More specifically, Figure 3 As shown, Figure 3A schematic diagram of the structure of a data exchange device 200 provided in an embodiment of the present application. The above-mentioned data exchange device 200 preferably includes: a data exchange module 203 and 8 data transmission modules 204. Among them, each data transmission module 204 includes a data sending module 2041 and a data receiving module 2042, and each data transmission module 204 is provided with a data port (not shown in the figure), and the data sending module 2041 and the data receiving module 2042 are connected to a data port together. The data transmission module 204 and the data exchange module 203 exchange data through internal data frames, and the address port self-learning module 202 and the data exchange module also exchange data through internal data frames.
[0056] In this method, the address port self-learning module 202 retrieves the mapping table from the storage module 201 through a table lookup instruction, and reads the second mapping relationship in the mapping table to determine whether to store the first mapping relationship in the mapping table. The address port self-learning module 202 can automatically read the second mapping relationship in the mapping table so that the mapping table can be automatically updated later, thereby realizing the self-learning of the terminal device address and the data port number. The updating efficiency of the mapping table is improved.
[0057] The following describes how the storage module 201 sends the mapping table to the address port self-learning module 202 according to the table lookup instruction. Figure 4 As shown, Figure 4 A schematic diagram of the structure of the storage module 201 provided in the embodiment of the present application. The storage module 201 includes: a RAM (Random Access Memory), a first RAM interface 2011, and a table lookup instruction parsing module 2012; the table lookup instruction parsing module 2012 parses the table lookup instruction to obtain a read instruction; the RAM 2013 sends the mapping table to the address port self-learning module 202 through the first RAM interface 2011 according to the read instruction.
[0058] More specifically, the mapping table is stored in the RAM 2013 of the storage module 201. The RAM 2013 has a random access feature, and the address port self-learning module 202 can read the RAM 2013 at any time without following a certain order. The RAM 2013 can send the mapping table to the address port self-learning module 202 through the first RAM interface 2011 at any time.
[0059] In this manner, due to the random access characteristic of RAM 2013, the flexibility of the address port self-learning module 202 in retrieving the mapping table is improved, thereby improving the efficiency and flexibility of the address port self-learning module 202 in updating the mapping table.
[0060] In one implementation, the address port self-learning module 202 sends an update instruction to the storage module 201, and the storage module 201 stores the mapping table according to the update instruction.
[0061] Specifically, the storage module 201 has a data writing function. The storage module 201 can respond to the update instruction sent by the address port self-learning module 202 in a timely manner, and write (store) the mapping table according to the guidance of the update instruction. Among them, the mapping table has been updated by the address port self-learning module 202.
[0062] In this manner, the storage module 201 can automatically store the updated mapping table without manual intervention, thereby reducing the risk of data inconsistency or error caused by human error and improving the accuracy and efficiency of mapping table storage.
[0063] The following describes the manner in which the storage module 201 stores the mapping table according to the update instruction. The storage module 201 also includes a second RAM interface 2014 and an update instruction parsing module 2015; the update instruction parsing module 2015 parses the update instruction to obtain a write instruction, and the RAM 2013 stores the mapping table through the second RAM interface 2014 based on the write instruction.
[0064] More specifically, RAM 2013 has a data writing function. RAM 2013 writes (stores) the mapping table according to the instruction of the write instruction. RAM 2013 can write the mapping table at any time without following a certain order. Among them, the mapping table has been updated by the address port self-learning module 202.
[0065] In this mode, due to the access characteristics of RAM 2013 at any time, the storage at any time of the mapping table is supported, and the flexibility of the mapping table storage is improved. In addition, this mode does not need to think that intervention has reduced the error rate of the mapping table storage.
