In order to better understand the technical solutions in the embodiments of the present application, the following descriptions will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the embodiments of the present application shall fall within the scope of protection of the embodiments of the present application.
The Transmission Control Protocol (TCP) is a connection-oriented, reliable, byte stream based transport layer communication protocol that is handled when the terminal device is performing TCP communication.
In order to improve the efficiency of the terminal device in performing TCP communication, the terminal device is coupled to a special data processor, when the terminal device sends data to be transmitted to the opposite terminal device, the terminal device establishes a Transmission Control Protocol (TCP) connection with the opposite terminal device, and then a TCP/IP protocol stack in the terminal device performs TCP encapsulation processing on the data to be transmitted, i.e. a TCP/IP header is sent, the terminal device needs to perform TCP connection establishment, and the TCP/IP protocol stack in the terminal device needs to perform encapsulation processing on the data to be transmitted, which occupies terminal device resources, affects normal processing speed of the terminal device, and increases time delay.
Therefore, a technology capable of improving the speed of TCP data communication by the terminal device and reducing the communication delay of the terminal device is needed.
Fig. 1 is a system architecture diagram for implementing a data communication method according to an embodiment of the present disclosure. The system architecture includes a first device, a second device, a first specialized data processor coupled to the first device, a second specialized data processor coupled to the second device, the first and second specialized data processors being for TCP data communication between the first and second devices.
The first device is a device that is to establish TCP data communications. It may be a client or a server. In particular, it may be embodied as a desktop computer, a laptop computer, a mobile phone, a PDA, a dedicated terminal, or as a cluster of several terminals, or it may be a part of a terminal, such as a virtual machine, that is divided.
The second device refers to a device that establishes TCP communication with the first device in response to a TCP communication request of the first device. It may be a client or a server. In general, when the first device is a client, the second device is a server; when the first device is a server, the second device is a client. In particular, it may also be embodied as a desktop computer, a laptop computer, a mobile phone, a PDA, a dedicated terminal, or as a cluster of several terminals, or it may be a part of a terminal, such as a virtual machine, that is divided.
TCP data communication refers to communication employing the TCP protocol. The TCP protocol is a connection-oriented, reliable, byte stream based transport layer communication protocol.
The first special data processor and the second special data processor are special Data Processors (DPU), the DPU is a special processor which is constructed by taking data as a center, and the software-defined technical route is adopted to support the virtualization of infrastructure layer resources and support the services of the infrastructure layer such as storage, security, service quality management and the like. Because the TCP data communication is to establish a TCP connection between the first device and the second device and transmit data through the TCP connection, the first device and the second device realize the TCP connection establishment and the data transmission between the first special data processor and the second special data processor, thereby saving the computing resources of the first device and the second device.
And TCP data communication is carried out between the first special data processor and the second special data processor through a network port. Since the first device is TCP connected to the second dedicated data processor through the first dedicated data processor, the first device may transmit data to the second device through an established TCP connection between the first dedicated data processor and the second dedicated data processor.
As shown in fig. 2, a data communication method 200 is provided according to one embodiment of the present disclosure. The method is performed by a first dedicated data processor through which the first device communicates data with a second device. The data communication method comprises the following steps:
step 210, acquiring a transmission control protocol connection establishment request for the second device from the first device through a first dedicated data channel between the first dedicated data processor and the first device;
step 220, in response to the transmission control protocol connection establishment request, establishing a transmission control protocol connection with the second device;
step 230, obtaining data to be transmitted from the first device through the first dedicated data channel;
step 240, encapsulating the data to be transmitted by using a transmission control protocol to obtain a first encapsulated message, and transmitting the first encapsulated message to the second device through the transmission control protocol connection.
Establishing a transmission control protocol connection with the second device in step 220 refers to the process of establishing a TCP connection with the second device through the running TCP/IP protocol stack. For example, a first TCP/IP protocol stack is run in the first dedicated data processor, and a second TCP/IP protocol stack is run in the second dedicated data processor, so after the first dedicated data processor obtains the transmission control protocol connection establishment request, a TCP connection can be established between the first dedicated data processor and the second TCP/IP protocol stack through the first TCP/IP protocol stack, so as to establish a transmission control protocol connection with the second dedicated data processor, that is, to establish a transmission control protocol connection with the second device.
The step 240 of encapsulating the data to be transmitted with the transmission control protocol refers to encapsulating the data to be transmitted with a TCP/IP protocol stack. For example, when a first TCP/IP protocol stack is running in the first special data processor, when the data to be transmitted is encapsulated by a transmission control protocol, the data to be transmitted is encapsulated by the first TCP/IP protocol stack by performing encapsulation processing such as TCP/IP header, so as to obtain a first encapsulated packet.
The steps 210-240 have the advantages that the first device does not need to send the encapsulated message to the first special data processor, but directly sends the bare packet of the data to be transmitted to the first special data processor in a special data channel mode, the channel ensures the communication security, does not occupy the terminal device resources, and improves the data communication efficiency. The TCP connection establishment and encapsulation process is not required on the first device for the data to be transmitted. Instead, the establishment of the TCP connection on the first device is moved to the first special data processor for execution, and the TCP encapsulation of the data to be transmitted of the TCP/IP protocol stack on the first device is moved to the TCP/IP protocol stack of the first special data processor for execution, so that the occupation of resources to the terminal device is reduced in TCP data communication, the TCP data communication speed is improved, and the communication time delay is reduced. Particularly, when the first device transmits a plurality of data to be transmitted to the opposite terminal device at the same time, the TCP/IP protocol stack in the first special data processor encapsulates different data to be transmitted to replace the plurality of TCP/IP protocol stacks in the first device for encapsulation, so that the data communication method of the embodiment of the invention can further reduce the occupation of resources to the terminal device, further improve the TCP data communication speed and reduce the communication delay.
The implementation of steps 210 and 230 is described in detail below.
As shown in fig. 3, in one embodiment, the first dedicated data channel includes a shared memory within the first dedicated data processor, based on which step 210 includes:
step 2101, periodically poll the shared memory to obtain a tcp connection establishment request in the shared memory.
Correspondingly, step 230 includes:
step 2301, periodically polling the shared memory to obtain data to be transmitted in the shared memory.
The tcp connection establishment request in step 2101 is generated by the first device and then placed in the shared memory, specifically, after the tcp connection establishment request is generated in the first device, the tcp connection establishment request may be copied to the shared memory according to the shared memory address shared by the first dedicated data processor to the first device.
The data to be transmitted in step 2301 is generated by the first device and then placed in the shared memory, and specifically, after the data to be transmitted is generated in the first device, the data to be transmitted may be copied to the shared memory according to the shared memory address shared by the first dedicated data processor to the first device.
It should be noted that, the copying of the transmission control protocol connection establishment request by the first device to the shared memory and the copying of the data to be transmitted by the first device to the shared memory may be performed simultaneously or sequentially, which is not limited by the embodiment of the present disclosure.
The beneficial effects of step 2101 and step 2301 are that the disclosed embodiment adopts a scheme of setting a shared memory in the first special data processor, so that the storage resource of the first device can be not occupied on the premise of ensuring the communication security between the first device and the first special data processor as much as possible, the resource occupation of the first device is reduced, the TCP data communication speed is improved, and the communication time delay is reduced.
As shown in fig. 4, in another embodiment, the first dedicated data channel includes a system on a chip internal to the first dedicated data processor, based on which step 210 includes:
step 2102, obtaining a transmission control protocol connection establishment request forwarded by the system on chip.
Correspondingly, step 230 includes:
step 2302, obtain the data to be transmitted forwarded by the system on chip.
The tcp connection establishment request in step 2102 is generated by the first device and then sent to the system on chip, specifically, after the tcp connection establishment request is generated in the first device, the tcp connection establishment request may be sent to the system on chip in the first dedicated data processor through an interface corresponding to the system on chip in the first device.
The data to be transmitted in step 2302 is generated by the first device and then sent to the system on chip, specifically, after the data to be transmitted is generated in the first device, the data to be transmitted may be sent to the system on chip of the first dedicated data processor through an interface corresponding to the system on chip in the first device.
It should be noted that, the sending of the transmission control protocol connection establishment request by the first device to the system on chip and the sending of the data to be transmitted by the first device to the system on chip may be performed simultaneously or sequentially, which is not limited in the embodiment of the present disclosure.
The advantages of step 2102 and step 2302 are that the embodiment of the present disclosure adopts a scheme of setting a system on chip in the first dedicated data processor, and since the system on chip can directly send the received transmission control protocol connection establishment request and the data to be transmitted to the first dedicated data processor, compared with the scheme of periodically polling the shared memory by the first dedicated data processor, the scheme of directly sending data by the system on chip adopted in the embodiment of the present disclosure can shorten the time of data communication, so as to improve the data communication efficiency.
The architecture within the first device is described in detail below with reference to fig. 1.
The first device comprises at least one source service container group, each source service container group having a source data interface unit; the transmission control protocol connection establishment request and the data to be transmitted are generated by a target source traffic container group of the at least one source traffic container group and sent to the first dedicated data channel via a source data interface unit inside the target source traffic container group.
The source service container groups are pod in the first device, each source service container group may have a third TCP/IP protocol stack running, and for each source service container group, the source data interface unit in the source service container group may be a socket interface of the third TCP/IP protocol stack in the source service container group, or may be a data interface replacing the socket interface, which is not limited in the embodiments of the present disclosure. The source service container group is provided with a source data interface unit, and the source data interface unit is provided with a first dedicated data channel.
Therefore, the source data interface unit in the target source service container group can directly acquire the data such as the transmission control protocol connection establishment request and the data to be transmitted, and the source data interface unit sends the data to the first special data channel, so that the data to be transmitted is not required to be packaged in the first equipment, the occupation of resources of the first equipment is reduced, the TCP data communication speed is improved, and the communication time delay is reduced.
In addition, the source data interface unit in the source service container group can be a socket interface of the third TCP/IP protocol stack in the source service container group, or can be a data interface replacing the socket interface, so that data such as data to be transmitted generated by a source service program running in the source service container group can be directly acquired by the source data interface unit, further, the data to be transmitted generated by the source service program can be sent to the second device through the first special data channel without being perceived, and the application side is not required to be adaptively modified, thereby improving the user experience.
The implementation of step 220 is described in detail below.
As shown in fig. 3 and 4, in one embodiment, the transmission control protocol connection establishment request has a source traffic container group identification and a second device identification, based on which step 220 includes:
Step 2201, based on the second device identifier, acquiring a second identifier of a second dedicated data processor coupled to the second device;
step 2202, based on the second identifier, sending a transmission control protocol handshake request to the second dedicated data processor;
step 2203, receiving, from the second dedicated data processor, the destination traffic container group identification allocated in the second device;
step 2204, binding the source service container group identifier, the first identifier of the first special data processor, the second identifier, and the destination service container group identifier, thereby establishing a transmission control protocol connection.
Wherein, as shown in fig. 6, the second device comprises at least one destination service container group, each destination service container group having a destination data interface unit; a second dedicated data channel is disposed between the second dedicated data processor and the second device, and the second dedicated data channel may be a shared memory disposed inside the second dedicated data processor or a system on chip disposed inside the second dedicated data processor.
The destination service container groups are pod in the second device, each destination service container group may have a fourth TCP/IP protocol stack running, and for each source service container group, the destination data interface unit in the destination service container group may be a socket interface of the fourth TCP/IP protocol stack in the destination service container group, or may be a data interface replacing the socket interface, which is not limited in this embodiment of the disclosure. Therefore, the destination service program running in the destination service container group can directly acquire the data to be transmitted through the destination data interface unit, and further the application can acquire the data sent by the first device through the first special data channel without perception, so that the application side does not need to carry out adaptive modification, and the user experience is improved.
In a specific embodiment, the second device comprises a destination traffic container group, based on which, after step 2202 and before step 2203, the second dedicated data processor may receive a transmission control protocol handshake request, where the second data processor may send identification request information to the second device through the second dedicated data channel and the destination data interface unit of the destination traffic container group, so that the second device sends the destination traffic container group identification to the second dedicated data processor through the second dedicated data channel and the destination data interface unit.
In another specific embodiment, the second device includes a plurality of destination service container groups, based on which, after step 2202 and before step 2203, the second dedicated data processor may receive a transmission control protocol handshake request, where the second data processor may send identification request information to the second device through a destination data interface unit that the second dedicated data channel and the destination service container groups have, so that the second device determines, among the plurality of destination service container groups, any destination service container group with the smallest load capacity or any destination service container group with the largest free capacity, and the second dedicated data channel and the destination data interface unit send, to the second dedicated data processor, a destination service container group identifier of the destination service container group, where the destination service container group identifier is a destination service container group identifier allocated in the second device.
The advantage of steps 2201-2204 is that, by adopting the scheme that the first special data processor and the second special data processor establish the transmission control protocol connection, the second device and the first special data processor can not be used for performing the transmission control protocol connection, thereby reducing the resource occupation of the second device, improving the efficiency of TCP communication and reducing the communication time delay.
The implementation process in step 240 is described in detail below.
As shown in fig. 3 and 4, step 240 includes:
packaging the data to be transmitted by a transmission control protocol to obtain a first packaged message (step 2401);
the first encapsulated packet is sent to a second dedicated data processor corresponding to the second identifier through a tcp connection (step 2402), so that after the second dedicated data processor decapsulates the first encapsulated packet (step 2403), the first encapsulated packet is sent to a destination service container group corresponding to the destination service container group identifier through a second dedicated data channel between the second dedicated data processor and the second device (step 2404).
Specifically, based on the second TCP/IP protocol stack running in the second dedicated data processor, in step 2403, the second dedicated data processor decapsulates the first encapsulated message by the second TCP/IP protocol stack.
The steps 2401-2404 have the advantages that the TCP connection between the first device and the second device can be realized by establishing the TCP connection between the first dedicated data processor and the second dedicated data processor, so that the occupation of terminal device resources can be reduced by performing encapsulation and decapsulation processing in the first dedicated data processor and the second dedicated data processor, and the TCP data communication efficiency is improved.
Alternatively, the first dedicated data processor may be provided with a first application for processing the received data, and the second dedicated data processor is provided with a second application for processing the received data, based on which:
the first special data processor can determine whether the data to be transmitted needs to be processed by the first application program after receiving the data to be transmitted, if so, the data to be transmitted is sent to the first application program, after the first application program processes the data to be transmitted to obtain updated data to be transmitted, the data to be transmitted is sent to a first TCP/IP protocol stack in the first special data processor, so that the first TCP/IP protocol stack encapsulates the data to be transmitted, and a first encapsulated message is obtained; otherwise, the data to be transmitted is directly encapsulated through a first TCP/IP protocol stack to obtain a first encapsulated message.
After the first special data processor sends the first encapsulated message to a second special data processor corresponding to the second identifier through a transmission control protocol connection, the second special data processor can determine whether the first encapsulated message needs to be processed by a second application program, if so, the first encapsulated message is decapsulated by a second TCP/IP protocol stack to obtain data to be transmitted, the data to be transmitted is sent to the second application program, after the second application program processes the data to be transmitted to obtain updated data to be transmitted, the data to be transmitted is sent to a destination service container group corresponding to the destination service container group identifier through a second special data channel between the second special data processor and the second device; otherwise, the second TCP/IP protocol stack in the second special data processor directly unpacks the first packed message to obtain data to be transmitted, and then the data to be transmitted is sent to the destination service container group corresponding to the destination service container group identifier through a second special data channel between the second special data processor and the second device.
The first application program and the second application program may be application programs that perform update processing on data to be transmitted, and a specific update manner of the update processing is not limited in the embodiment of the present application.
Compared with the prior art that the first special data processor receives the encapsulated data to be transmitted, the first special data processor needs to unpack the data and then process the data through the first application program.
As shown in fig. 3 and 4, in one embodiment, the data communication method further includes:
receiving a second encapsulated message sent by a second special data processor corresponding to the second identifier through a transmission control protocol connection (step 250);
the second encapsulated message is subjected to tcp decapsulation to recover the reply data (step 260), and the reply data is sent to the source service container group corresponding to the source service container group identifier through the first dedicated data channel (step 270).
The second encapsulated packet in step 250 is generated by the second dedicated data processor corresponding to the second identifier receiving response data from the destination service container set corresponding to the destination service container set identifier through the second dedicated data channel, and encapsulating the response data by using a transmission control protocol.
Specifically, before step 250, the second device may generate response data according to the received data to be transmitted, and then send the response data to the second special data processor through the destination data interface unit and the second special data channel, so that the second TCP/IP protocol stack in the second special data processor encapsulates the response data to obtain a second encapsulated packet, and the second special data processor may send the second encapsulated packet to the first special data processor through the transmission control protocol connection, so that in step 250, the first special data processor may receive the second encapsulated packet.
In step 260, after the first dedicated data processor receives the second encapsulated packet, the second encapsulated packet may be decapsulated by the first TCP/IP protocol stack to recover the reply data.
The steps 250-270 have the advantages that when the response data sent by the second device is sent to the first device through the first special data processor, the second device does not need to send the packaged message to the second special data processor, but directly sends the bare packet of the response data to the second special data processor in a special data channel mode, the channel ensures the communication safety, does not occupy terminal equipment resources, and improves the TCP data communication efficiency. And the received message is not required to be subjected to decapsulation processing on the first device. Instead, the TCP decapsulation operation of the encapsulated message of the TCP/IP protocol stack on the first device is moved to the TCP/IP protocol stack of the first special data processor for execution, so that the occupation of resources on terminal equipment is reduced in TCP data communication, the TCP data communication speed is improved, and the communication time delay is reduced.
