TECHNICAL FIELD

[0001] The present application belongs to the field of communication, and particularly relates to a communication method, a board card, an energy storage valve control system and a storage medium. BACKGROUND

[0002] The energy storage valve control system usually adopts a multi-board card design (for example, a control board, an interface board, an input / output board, a display panel, etc.), and each board card can have different functions or architectures. The application software configured on these board cards can run based on an operating system or directly based on a processor, and the physical communication interface between the board cards can be a point-to-point communication bus interface or a shared bus interface, such as an Ethernet interface, an RS485 interface, a Controller Area Network (CAN) interface, a Low-Voltage Differential Signaling (LVDS) interface, etc.

[0003] At present, the communication mode between the board cards is usually a physical signal interface based on the same operating system driver, and the portability, scalability and flexibility are poor. SUMMARY

[0004] Therefore, the embodiments of the present application provide a communication method, a board card, an energy storage valve control system and a storage medium, aiming at solving the problem that the current communication mode between the board cards is usually a physical signal interface based on the same operating system driver, and the portability, scalability and flexibility are poor.

[0005] A first aspect of the embodiments of the present application provides a communication method, which is realized based on a communication system running on a board card. The communication system includes a driver layer, an operating system layer and an application layer, and further includes a unified system communication interface layer established between the operating system layer and the application layer. The communication method includes the following steps.

[0006] Through a first process, a source port corresponding to the first process is started to obtain a first communication channel identifier, and first data is written into a first shared space according to the first communication channel identifier;

[0007] Through an inter-board communication agent, a destination port corresponding to the inter-board communication agent is started to obtain the first communication channel identifier, and the first data is read from the first shared space according to the first communication channel identifier;

[0008] Through the inter-board communication agent, a port number of the destination port corresponding to the inter-board communication agent is written into the first data to generate first target data;

[0009] Through the inter-board communication agent, the first target data is sent to the driver layer;

[0010] by the driving layer, the at least one physical communication interface of the board card sends the first target data to the physical communication interface of the at least one other board card;

[0011] The unified system communication interface layer includes the inter-board communication agent, the destination port corresponding to the inter-board communication agent, and the source port corresponding to the first process.

[0012] In a first aspect, a communication method based on a communication system running on a board card is provided. A unified system communication interface layer is established between an operating system layer and an application layer of the communication system. At least one set of source ports and destination ports is preconfigured in the unified system communication interface layer based on an inter-board communication agent of the unified system communication interface layer according to actual needs. A communication channel identifier and a shared space are established according to a port number of each set of virtual ports (i.e., source ports and destination ports) to establish a mapping relationship between each set of virtual ports. In the case where inter-board communication is needed and a user does not know an address of a data receiver, the user can achieve communication between different board cards without knowing the address of the data receiver based on the mapping relationship between each set of virtual ports. The type of an operating system running on different board cards is not limited. This inter-board communication method is transparent to the user (user transparency means that the user does not need to care about a specific communication implementation method, which is transparent and invisible to the user, and the user only needs to use it). By pre-establishing a mapping relationship between different virtual ports, a data sender (i.e., a first process) and a data receiver (i.e., at least one other board card) can be flexibly bound, so that different data routing can be achieved, and the method can be applied to any board card, and has good portability, scalability, and flexibility. The first aspect can achieve one-way data sending from a board card to at least one other board card, i.e., one-to-one or one-to-many.

[0013] In a first implementation manner of the first aspect, before the first process is started, the source port corresponding to the first process is opened to obtain a first communication channel identifier, and the first data is written into a first shared space according to the first communication channel identifier, the method further includes:

[0014] The inter-board communication agent establishes a globally unique first communication channel identifier and a globally unique first shared space according to a port number of the source port corresponding to the first process and a port number of the destination port corresponding to the inter-board communication agent.

[0015] In the first implementation manner of the first aspect, the first communication channel identifier and the first shared space are established based on the source port corresponding to the first process and the destination port corresponding to the inter-board communication agent according to the user configuration before inter-board communication is performed, so that the mapping between the source port corresponding to the first process and the destination port corresponding to the inter-board communication agent is implemented based on the first communication channel identifier, and the first process writes data and the inter-board communication agent reads data based on the first communication channel identifier and the first shared space, so as to implement the communication between the first process and the inter-board communication agent, and further implement the communication between the first process and other boards, which is good in scalability and flexibility.

[0016] In the second implementation manner of the first aspect, the number of the destination ports corresponding to the inter-board communication agent is multiple, and each of the destination ports corresponding to the inter-board communication agent is mapped with a source port corresponding to the first process, based on the first or second implementation manner of the first aspect.

[0017] The communication method further includes:

[0018] In the case that the inter-board communication agent generates multiple first target data, the inter-board communication agent packs and sends all the first target data to the drive layer.

[0019] In the second implementation manner of the first aspect, in the case that the number of the destination ports corresponding to the inter-board communication agent is multiple, the inter-board communication agent generates multiple first target data according to the first data sent by multiple first processes based on the mapping relationship between each of the destination ports corresponding to the inter-board communication agent and a source port corresponding to the first process, and packs and sends the first target data to the drive layer, so as to send the first target data to other boards through the drive layer, thereby realizing one-way batch data communication between different boards. The second implementation manner of the first aspect can realize one-way batch sending of data from a board to at least one other board.

[0020] In the third implementation manner of the first aspect, the communication method further includes:

[0021] The drive layer drives the physical communication interface of the board to receive second target data sent by the physical communication interface of at least one other board.

[0022] The second target data is acquired and parsed by the inter-board communication agent to obtain a port number of a destination port corresponding to another inter-board communication agent and second data, the port number of the destination port corresponding to the another inter-board communication agent being the same as the port number of the source port corresponding to the inter-board communication agent, the another inter-board communication agent running on the another board card;

[0023] The source port corresponding to the inter-board communication agent is started according to the port number of the destination port corresponding to the another inter-board communication agent, to obtain a second communication channel identifier, and the second data is written into a second shared space according to the second communication channel identifier;

[0024] The destination port corresponding to the second process is started to obtain the second communication channel identifier, and the second data is read from the second shared space according to the second communication channel identifier;

[0025] The unified system communication interface layer further includes the source port corresponding to the inter-board communication agent and the destination port corresponding to the second process.

[0026] In the third implementation manner of the first aspect, based on the mapping relationship between each group of virtual ports of the board card that is established in advance, the port number of the source port corresponding to the inter-board communication agent of the board card is made the same as the port number of the destination port corresponding to the another inter-board communication agent of the another board card, so that the mapping relationship between the virtual ports of different board cards is established, so that the user can realize the communication between different board cards based on the mapping relationship between the virtual ports of different board cards without knowing the address of the data receiving party, without needing to know the address of the data receiving party, and without being limited to the type of operating system running on different board cards. This inter-board communication mode is transparent to the user. Based on this, the data sender (that is, the another board card) and the data receiving party (that is, the second process) can be flexibly bound by establishing the mapping between the virtual ports of different board cards in advance, so that different data routing can be performed, and the method can be applied to any board card and has good portability, scalability and flexibility. In the third implementation manner of the first aspect, based on the first aspect, the board card can one-way receive data sent by at least one another board card, that is, one-to-one or multiple-to-one, so that bidirectional data communication between different board cards is realized as a whole.

[0027] In the fourth implementation manner of the first aspect, based on the third implementation manner of the first aspect, before the physical communication interface of the board card receives the second target data sent by the physical communication interface of the another board card by driving the driving layer, the method further includes:

[0029] In the fourth implementation manner of the first aspect, before the inter-board communication, the inter-board communication agent establishes a common and globally unique second communication channel identifier and a common and globally unique second shared space according to a port number of a source port corresponding to the inter-board communication agent and a port number of a destination port corresponding to the second process based on the actual needs of the user, so as to realize the mapping between the source port corresponding to the inter-board communication agent and the destination port corresponding to the second process based on the second communication channel identifier, and realize the inter-board communication agent writing data and the second process reading data based on the second communication channel identifier and the second shared space, thereby realizing the communication between the inter-board communication agent and the second process, and further realizing the communication between the second process and other board cards, which is good in scalability and flexibility.

[0030] In the fifth implementation manner of the first aspect, the number of the source ports corresponding to the inter-board communication agent is multiple, and each source port corresponding to the inter-board communication agent is mapped with a destination port corresponding to one second process.

[0031] The communication method further includes:

[0032] In the case that the inter-board communication agent obtains the packaged multiple second target data, the inter-board communication agent unpacks and parses all the second target data to obtain the port numbers of the multiple source ports corresponding to the inter-board communication agent and the multiple second data.

[0033] In the fifth implementation manner of the first aspect, in the case that the number of the source ports corresponding to the inter-board communication agent is multiple, the inter-board communication agent can unpack to obtain the port numbers of the multiple destination ports corresponding to other inter-board communication agents and the multiple second data in the case that it receives the packaged multiple second target data sent by at least one other board card, and then distribute the multiple second data to each second process based on the mapping relationship between each group of virtual ports of different board cards and the mapping relationship between each group of virtual ports of the same board card, so as to realize the one-way batch data communication between different board cards. The fifth implementation manner of the first aspect can realize that the board card receives the batch data sent by at least one other board card in one way.

[0034] In a sixth implementation form of the first aspect, in any of the third or fourth implementation form of the first aspect, the second process and the first process are the same process.

[0035] In the sixth implementation form of the first aspect, in the case that the second process and the first process are the same process, bidirectional communication between the same process in the board and the inter-board communication agent can be implemented.

[0036] In a seventh implementation form of the first aspect, based on the first aspect or any one of the first to sixth implementation forms of the first aspect, the communication method further includes:

[0037] opening, by the third process, a source port corresponding to the third process to obtain a third communication channel identifier, and writing third data into a third shared space according to the third communication channel identifier;

[0040] In the seventh implementation form of the first aspect, based on the pre-established mapping relationship between each group of virtual ports, in the case that intra-board communication is needed and the user does not know the address of the data receiver, the user does not need to know the address of the data receiver, and communication between different processes in the same board can be implemented, which is transparent to the user. Based on this, by pre-establishing the mapping between different virtual ports, the data sender (i.e., the third process) and the data receiver (i.e., the fourth process) can be flexibly bound, so that different data routing can be performed, which can be applied to any board and has good portability, scalability and flexibility.

[0041] In an eighth implementation form of the first aspect, based on the seventh implementation form of the first aspect, the unified system communication interface layer further includes an intra-board communication agent.

[0042] Before the opening, by the third process, of the source port corresponding to the third process to obtain the third communication channel identifier and the writing of the third data into the third shared space according to the third communication channel identifier, the method further includes:

[0043] establishing, by the intra-board communication agent, a globally unique third communication channel identifier and a globally unique third shared space according to a port number of the source port corresponding to the third process and a port number of the destination port corresponding to the fourth process.

[0110] In application, the port number of the destination port corresponding to the inter-board communication agent and the port number of the source port corresponding to the inter-board communication agent of other board are set to be the same and globally unique according to the actual needs of the user in advance, so as to establish the mutual mapping relationship between the destination port corresponding to the inter-board communication agent and the source port corresponding to the inter-board communication agent of other board, so that after the first target data carrying the port number of the destination port corresponding to the inter-board communication agent is received, the other board can start the source port corresponding to the inter-board communication agent with the mapping relationship according to the port number of the destination port corresponding to the inter-board communication agent, and send the first data to other processes according to the corresponding relationship between the source port corresponding to the inter-board communication agent and the destination port corresponding to other processes on the other board.

[0111] In application, the inter-board communication agent triggers the drive layer to drive the at least one physical communication interface of the board to send the first target data to the physical communication interface of the at least one other board, so as to realize one-to-one or one-to-many. When one-to-many is realized, each physical communication interface of the board sends the first target data to the physical communication interface on one other board.

[0112] In one embodiment, before step S101, it comprises:

[0113] Through the inter-board communication agent, the globally unique first communication channel ID and the globally unique first shared space are established according to the port number of the source port corresponding to the first process and the port number of the destination port corresponding to the inter-board communication agent.

[0114] In application, before the first inter-board communication is performed, the port number of the source port corresponding to the first process and the port number of the destination port corresponding to the inter-board communication agent are configured by the inter-board communication agent according to the actual needs of the user, and then the globally unique first communication channel ID and the globally unique first shared space are established according to the port numbers of the virtual ports. The first communication channel ID is used to realize the mapping between the source port corresponding to the first process and the destination port corresponding to the inter-board communication agent, so that the first process can send the first data to the mutually mapped destination port corresponding to the inter-board communication agent after starting the corresponding source port. The specific implementation manner is that the first process writes the first data into the first shared space according to the first communication channel ID, and the inter-board communication agent reads the first data from the first shared space according to the first communication channel ID, so as to realize the communication between the first process and the inter-board communication agent, and further realize the communication between the first process and other boards. The scalability and flexibility are good.

[0115] In one embodiment, the destination port corresponding to the inter-board communication agent is multiple, and each destination port corresponding to the inter-board communication agent is mutually mapped with the source port corresponding to one first process;

[0116] The communication method further includes the following steps for implementing the second one-way inter-board communication (specifically, one-way batch data transmission from the board card to at least one other board card):

[0117] In the case where the plurality of first target data are generated by the inter-board communication agent, the inter-board communication agent packages and transmits all the first target data to the driver layer.

[0118] In the application, in the case where the number of destination ports corresponding to the inter-board communication agent is multiple, the plurality of first processes can simultaneously transmit data to the inter-board communication agent through the corresponding source ports. The principle of one-way data transmission from each first process to the inter-board communication agent is the same as steps S101 to S103, which will not be described here. The inter-board communication agent can generate a plurality of first target data according to the first data transmitted by the plurality of first processes, respectively, and then package and transmit all the first target data to the driver layer for transmission to other board cards through the driver layer, so as to realize one-way batch data communication between different board cards.

[0119] As shown in FIG. 2, Figure 3 The communication method provided by the embodiment of the application further includes the following steps S201 to S204 for implementing the third one-way inter-board communication (specifically, one-way reception of data transmitted by at least one other board card):

[0120] Step S201, receiving, through the driver layer, second target data transmitted by the physical communication interface of at least one other board card through the physical communication interface of the board card, and entering step S202.

[0121] In the application, the inter-board communication agent triggers the driver layer to drive at least one physical communication interface of the board card to receive second target data transmitted by the physical communication interface of at least one other board card, to realize one-to-one or one-to-many. In the case of one-to-many, each physical communication interface of the board card receives second target data transmitted by the physical communication interface on one other board card.

[0122] Step S202, acquiring and analyzing the second target data through the inter-board communication agent to obtain the port number of the source port corresponding to the other inter-board communication agent and the second data, and entering step S203.

[0123] In application, the port number of the source port corresponding to the inter-board communication agent and the port number of the destination port corresponding to the other inter-board communication agent are set to be the same and globally unique according to the actual needs of the user in advance, so as to establish the mutual mapping relationship between the source port corresponding to the inter-board communication agent and the destination port corresponding to the other inter-board communication agent, so that after the inter-board communication agent obtains the second data carrying the port number of the destination port corresponding to the other inter-board communication agent, the inter-board communication agent corresponding to the source port with the mapping relationship can be started according to the port number of the destination port corresponding to the other inter-board communication agent, and the second data can be sent to the second process according to the corresponding relationship between the source port corresponding to the inter-board communication agent and the destination port corresponding to the second process running on the board card.

[0124] In step S203, the inter-board communication agent starts the source port corresponding to the inter-board communication agent according to the port number of the source port corresponding to the other inter-board communication agent, obtains the second communication channel ID, and writes the second data into the second shared space according to the second communication channel ID, and enters step S204.

[0125] In step S204, the second process starts the destination port corresponding to the second process to obtain the second communication channel ID, and reads the second data from the second shared space according to the second communication channel ID.

[0126] In application, the second process can be any process running on the board card that needs to receive data sent by other processes running on other board cards. According to the actual needs of the user, the inter-board communication agent configures a group of virtual ports including the destination port corresponding to the second process and the source port corresponding to the inter-board communication agent on the USCI layer of the board card in advance, and then the inter-board communication agent establishes a globally unique second communication channel ID and a globally unique second shared space according to the port numbers of the virtual ports. The second communication channel ID is stored in the second shared space.

[0127] In application, the process of the inter-board communication agent unidirectionally sending the second data to the second process is as follows:

[0128] The inter-board communication agent starts the source port corresponding to the inter-board communication agent according to the port number of the destination port corresponding to the other inter-board communication agent, reads the globally unique second communication channel ID from the second shared space, and writes the second data into the second shared space according to the second communication channel ID;

[0129] The second process starts the destination port corresponding to the second process, reads the globally unique second communication channel ID from the second shared space, and reads the second data from the second shared space according to the second communication channel ID, so as to realize the unidirectional sending of the second data from the inter-board communication agent to the second process.

[0130] In one embodiment, before step S201, the following steps are included:

[0131] Through the inter-board communication agent, a globally unique second communication channel ID and a globally unique second shared space are established according to the port number of the source port corresponding to the inter-board communication agent and the port number of the destination port corresponding to the second process.

[0132] In the application, before the third inter-board communication is performed, the port number of the destination port corresponding to the first process and the port number of the source port corresponding to the inter-board communication agent are configured according to the actual needs of the user in advance through the inter-board communication agent, and then a globally unique second communication channel ID and a globally unique second shared space are established according to the port numbers of the set of virtual ports. The second communication channel ID is used to realize the mapping between the destination port corresponding to the second process and the source port corresponding to the inter-board communication agent, so that the inter-board communication agent can send the second data to the destination port corresponding to the first process after the corresponding source port is opened. The specific implementation manner is that the inter-board communication agent writes the second data into the second shared space according to the second communication channel ID, and the second process reads the second data from the second shared space according to the second communication channel ID, so as to realize the communication between the inter-board communication agent and the second process, and further realize the communication between the second process and other board cards. The scalability and flexibility are good.

[0133] In one embodiment, the number of source ports corresponding to the inter-board communication agent is multiple, and each source port corresponding to the inter-board communication agent is mapped with a destination port corresponding to a second process.

[0134] The above communication method further includes the following steps for realizing the fourth one-way inter-board communication (specifically, the board card receives the data sent by at least one other board card in a one-way batch manner):

[0135] In the case that the packaged multiple second target data are obtained through the inter-board communication agent, the inter-board communication agent is used to unpack and parse all the second target data to obtain the port numbers of multiple destination ports corresponding to other inter-board communication agents and multiple second data.

[0136] In the application, in the case that the number of source ports corresponding to the inter-board communication agent is multiple, the inter-board communication agent can receive the packaged multiple second target data sent by at least one other board card, and then unpack the multiple second target data to obtain the port numbers of multiple destination ports corresponding to the other inter-board communication agents and the multiple second data. Then, based on the mapping relationship between each group of virtual ports of different board cards and the mapping relationship between each group of virtual ports of the same board card, the multiple source ports corresponding to the inter-board communication agent can simultaneously send data to multiple second processes in one direction, so as to realize one-way batch data communication between different board cards. The principle and steps of each source port of the inter-board communication agent sending data to the second process in one direction are the same as steps S203 and S204, which will not be described here.

[0137] In one embodiment, the second process and the first process can be the same process. Based on the steps of the first one-way inter-board communication and the fourth one-way inter-board communication, bidirectional communication between the same process in the board card and the inter-board communication agent can be realized, and then bidirectional communication between the same process in the board card and other board cards can be realized.

[0138] In the application, the board card and other board cards realize communication based on the above communication method. In the case that the board card uses Figure 2 the corresponding communication method to send data to at least one other board card in one direction, the other board card can use Figure 3 the corresponding communication method to receive the data sent by the board card in one direction; similarly, in the case that the board card uses Figure 3 the corresponding communication method to receive data sent by at least one other board card in one direction, the other board card can use Figure 2 the corresponding communication method to send data to the board card in one direction.

[0139] Based on Figure 1 , Figure 4 The exemplary structure diagram of bidirectional communication between two different board cards is shown in the case that the second process and the first process are the same process;

[0140] Among them, the board card 100 is Figure 1 the board card in the corresponding embodiment;

[0141] In the board card 200, the source port 235-1 corresponding to the inter-board communication agent 231 and the destination port 234-3 corresponding to the process 242 are mapped to each other, which is used to realize one-way data sending from the inter-board communication agent 231 to the process 242;

[0142] The source port 234-4 corresponding to the process 242 and the destination port 235-2 corresponding to the inter-board communication agent 231 are mapped to each other, which is used to realize one-way data sending from the process 241 to the inter-board communication agent 231;

[0143] The port number of the destination port 135-1 corresponding to the inter-board communication agent 131 is the same as the port number of the source port 235-1 corresponding to the inter-board communication agent 231, and the port number of the destination port 235-2 corresponding to the inter-board communication agent 231 is the same as the port number of the source port 135-2 corresponding to the inter-board communication agent 131.

[0144] The physical communication interface 102 is connected with the physical communication interface 202.

[0145] As shown in FIG. 1, the communication method provided by the embodiment of the present application further includes the following steps S301 and S302 for realizing the first one-way intra-board communication (specifically, one-way sending of data from the third process to the fourth process): Figure 5

[0146] In step S301, the third process is used to open the source port corresponding to the third process, to obtain the third communication channel ID, and to write the third data into the third shared space according to the third communication channel ID, and then step S302 is entered.

[0147] In step S302, the fourth process is used to open the destination port corresponding to the fourth process, to obtain the third communication channel ID, and to read the third data from the third shared space according to the third communication channel ID.

[0148] In application, the third process and the fourth process can be any two different processes running on the board card, the third process sends the third data to the fourth process, and the fourth process receives the third data sent by the third process. According to the actual needs of the user, the source port corresponding to the third process and the destination port corresponding to the fourth process are configured by the intra-board communication agent in the USCI layer of the board card, and then the globally unique third communication channel ID and the globally unique third shared space are established by the intra-board communication agent according to the port numbers of the virtual ports, and the third communication channel ID is stored in the third shared space.

[0149] In application, the process of one-way sending of the third data from the third process to the fourth process is as follows:

[0150] The third process opens the source port corresponding to the third process, reads the globally unique third communication channel ID from the third shared space, and writes the third data into the third shared space according to the third communication channel ID;

[0151] The fourth process opens the destination port of the fourth process, reads the globally unique third communication channel ID from the third shared space, and reads the third data from the third shared space according to the third communication channel ID, thereby realizing one-way sending of the third data from the third process to the inter-board communication agent.

[0152] In one embodiment, before step S301, the following steps are included: ​

[0153] The plate-in communication agent establishes a globally unique third communication channel ID and a globally unique third shared space according to a port number of the source port corresponding to the third process and a port number of the destination port corresponding to the fourth process.

[0154] In the application, before the first plate-in communication is performed, the plate-in communication agent is used to configure the port number of the source port corresponding to the third process and the port number of the destination port corresponding to the fourth process according to the actual needs of the user, and then a globally unique third communication channel ID and a globally unique third shared space are established according to the port numbers of the set of virtual ports. The third communication channel ID is used to realize the mapping between the source port corresponding to the third process and the destination port corresponding to the fourth process, so that the third process can direct the third data to the destination port corresponding to the fourth process after the corresponding source port is opened.

[0155] As shown in FIG. 4, the communication method provided by the embodiment of the application further includes the following steps S401 and S402 for realizing the second one-way plate-in communication (specifically, the fourth process sends data to the third process in one direction): Figure 6

[0156] Step S401: The fourth process is used to open the source port corresponding to the fourth process to obtain a fourth communication channel ID, and the fourth data is written into a fourth shared space according to the fourth communication channel ID, and then step S402 is entered.

[0157] Step S402: The third process is used to open the destination port corresponding to the third process to obtain the fourth communication channel ID, and the fourth data is read from the fourth shared space according to the fourth communication channel ID.

[0158] In the application, based on the principle of identity, the fourth process can also send the fourth data to the third process, and the third process receives the fourth data sent by the fourth process. According to the actual needs of the user, the plate-in communication agent is used to configure the set of virtual ports including the source port corresponding to the fourth process and the destination port corresponding to the third process on the USCI layer of the board card, and then the plate-in communication agent is used to establish a globally unique fourth communication channel ID and a globally unique fourth shared space according to the port numbers of the set of virtual ports. The fourth communication channel ID is stored in the fourth shared space.

[0159] In the application, the process in which the fourth process sends the fourth data to the third process in one direction is as follows:

[0160] The fourth process opens the source port corresponding to the fourth process, reads the globally unique fourth communication channel ID from the fourth shared space, and writes the fourth data into the fourth shared space according to the fourth communication channel ID.

[0161] ​The third process opens a destination port of the third process, reads a globally unique fourth communication channel ID from the fourth shared space, and reads fourth data from the fourth shared space according to the fourth communication channel ID, so that the fourth process unidirectionally sends the fourth data to the inter-board communication agent.

[0162] Before step S401, in one embodiment, the following steps are included:

[0163] The inter-board communication agent establishes a globally unique fourth communication channel ID and a globally unique fourth shared space according to the port number of the source port corresponding to the fourth process and the port number of the destination port corresponding to the third process.

[0164] In an application, before the second kind of intra-board communication is performed, the port number of the source port corresponding to the fourth process and the port number of the destination port corresponding to the third process are configured according to actual needs of a user through the inter-board communication agent, and then a globally unique fourth communication channel ID and a globally unique fourth shared space are established according to the port numbers of the set of virtual ports. The fourth communication channel ID is used to realize mapping between the source port corresponding to the fourth process and the destination port corresponding to the third process, so that the fourth process can directively send fourth data to the destination port corresponding to the third process after the corresponding source port is opened.

[0165] In an application, based on the steps of the first kind of unidirectional intra-board communication and the second kind of unidirectional intra-board communication, bidirectional communication between different processes in a board card can be realized.

[0166] Based on Figure 1 , Figure 7 An exemplary bidirectional communication architecture diagram between different processes in the same board card is shown in FIG. 1.

[0167] The source port 133-1 corresponding to the process 141 and the destination port 134-1 corresponding to the process 142 are mutually mapped, and are used to realize unidirectional data sending from the process 141 to the process 142.

[0168] The source port 134-2 corresponding to the process 142 and the destination port 133-2 corresponding to the process 141 are mutually mapped, and are used to realize unidirectional data sending from the process 142 to the process 141.

[0169] In one embodiment, the third process or the fourth process can be the same process as the first process, and communication between the same process in the board card and other processes in the board and other processes outside the board can be realized.
