Detailed Description
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.
For data transmission between different service container groups of the terminal device, a dedicated data processor is usually coupled to the terminal device in order to reduce the resource occupation of the terminal device. The special data processor is a special hardware accelerator, has the characteristics of high performance and low delay, and can effectively process and manage different types of traffic.
Before the terminal equipment transmits the message through the TCP connection between the service container groups in the terminal equipment, the TCP connection is established first, and the message to be transmitted is encapsulated and decapsulated through the service container groups in the terminal equipment during the message transmission, so that more computing resources of the terminal equipment are occupied, the normal processing capacity of the terminal equipment is affected, and the communication time delay is increased.
Therefore, there is a need for a technique that can reduce the processing load of a terminal device and reduce the communication delay when data is transmitted between different service container groups of the terminal device.
Fig. 1 is a system architecture diagram for implementing a data transmission method according to an embodiment of the present disclosure. The system architecture includes a target device and a dedicated data processor. The target device comprises a plurality of service container groups, any two service container groups in the plurality of service container groups are respectively a first service container group and a second service container group, the special data processor is coupled with the target device, the special data processor is used for data transmission among the service container groups in the target device, and the first service container group transmits data to be transmitted to the second service container group through the special data processor.
The target device is a carrier device of a group of traffic containers in communication with each other. 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 service container groups are pod in the target equipment, and each service container group is internally provided with a service program so as to isolate the service programs in different service container groups.
A dedicated Data Processor (DPU) is a data-centric dedicated processor that supports infrastructure layer resource virtualization using software-defined technology routes, supporting infrastructure layer services such as storage, security, quality of service management, etc. The DPU can release the target device from the data forwarding processing work among the service container groups in the DPU, and the data forwarding processing is not needed in the target device, so that the processing load of the target device is reduced.
As shown in fig. 2, according to one embodiment of the present disclosure, there is provided a data transmission method 200, which is performed by a dedicated data processor, the data transmission method including:
Receiving data to be transmitted sent by a first service container group through a first dedicated data channel between the target device and the dedicated data processor (step 210);
acquiring identification information of a second service container group from data to be transmitted (step 220);
acquiring first virtual port information corresponding to the identification information of the second service container group, wherein the first virtual port is an entry of a second special data channel between the target device and the special data processor on the special data processor side (step 230);
the data to be transmitted is sent to the first virtual port indicated by the first virtual port information (step 240) so that the data to be transmitted is sent to the second set of traffic containers via the second dedicated data channel without establishing a transmission control protocol connection (step 250).
The first dedicated data channel in step 210 includes a virtual port group corresponding to the first service container group and disposed in a physical port, where the physical port refers to a portion of the dedicated data processor connected to the target device, and a plurality of virtual port groups are disposed in the physical port, and for each service container group in the target device, the service container group corresponds to one virtual port group one to one, and virtual port groups corresponding to different service container groups in the target device are different. The virtual port group includes an entry on the target device side and an entry on the dedicated data processor side.
The data to be transmitted in step 220 is generated by running a service program in the first service container group and is used for being sent to the second service container group, the data to be transmitted includes quintuple information, and the identification information of the second service container group can be obtained from the quintuple information of the data to be transmitted.

Specifically, in step 230, after the dedicated data processor obtains the identification information of the second service container group, the dedicated data processor may determine the second virtual port information corresponding to the identification information by looking up a preset table or traversing, etc., so as to determine the unique identification information of the second virtual port corresponding to the second service container group, and further obtain the first virtual port information corresponding to the second virtual port information, that is, the unique identification information of the first virtual port. The unique identification information may be a unique port number or a unique port name of the corresponding port, or the like.
The advantage of steps 210 to 250 is that the first service container group in the target device directly sends the data to be transmitted to the dedicated data processor through the first dedicated data channel, and after the dedicated data processor processes the data to be transmitted to obtain the first virtual port information, the received data to be transmitted is directly sent to the second service container group in the target device through the second dedicated data channel, so that the communication between the first service container group and the second service container group in the target device does not need to establish a transmission control protocol connection, and the data to be transmitted does not need to be encapsulated or decapsulated, so that the TCP/IP layers in the first service container group and the second service container group do not need to process the data to be transmitted, thereby reducing the processing load on the side of the target device, reducing the occupation of computing resources of the terminal device, and realizing the reduction of communication delay.
In addition, the first service container group directly sends the bare packet of the data to be transmitted to the special data processor through the first special data channel, so that the communication between the first service container group and the second service container group does not need to establish transmission control protocol connection, and a protocol stack in the special data processor does not need to check the integrity and consistency of the data to be transmitted, so that the communication efficiency can be improved on the premise of ensuring the communication safety as much as possible.
The implementation of steps 210, 220 and 240 is described in detail below.
As shown in fig. 3, in one embodiment, step 210 includes:
step 211, receiving, by the target storage unit, data to be transmitted sent by the first service container group through the first dedicated data channel.
Based on this, step 220 comprises:
step 221, obtaining the identification information of the second service container group from the data to be transmitted in the target storage unit to outside the target storage unit.
Step 240 includes:
and 241, sending the data to be transmitted to the first virtual port indicated by the first virtual port information from the target storage unit.
Specifically, the dedicated data processor may have a protocol stack running therein, based on which:
in step 220, the dedicated data processor may obtain the identification information of the second service container group from the data to be transmitted in the target storage unit, so that the protocol stack processes the identification information of the second service container group.
In step 230, the protocol stack of the dedicated data processor may be utilized to determine the first virtual port information corresponding to the second service container group according to the identification information of the second service container group, for example, a preset table is stored in the dedicated data processor, where the preset table includes at least a first preset table entry and a second preset table entry, for each service container group in the target device, the first preset table entry is used to record the first unique identification of the service container group, the second unique identification of the virtual port group corresponding to the service container group on the target device side, and the correspondence between the first unique identification and the second unique identification, and the second preset table entry is used to record the third unique identification of the virtual port group corresponding to the service container group on the dedicated data processor side, the second unique identification in the service container group, and the correspondence between the second unique identification and the third unique identification.
The step 211, the step 221 and the step 241 have the advantages that the first service container group in the target device sends the data to be transmitted to the target storage unit in the special data processor through the first special data channel, the target storage unit obtains the identification information of the second service container group from the data to be transmitted and processes the identification information to the outside of the target storage unit to obtain the first virtual port information, the first virtual port information can be determined, the data to be transmitted is directly sent to the first virtual port from the target storage unit according to the first virtual port information, and further the target storage unit in the special data processor does not need to read the complete data to be transmitted to the outside of the target storage unit to process the data to be transmitted to obtain the first virtual port information after receiving the data to be transmitted, and the target storage unit also directly sends the data to be transmitted from the target storage unit when sending the data to the second service container group, so that the data transmission program of the special data processor is saved, and the data communication efficiency of the special data processor is improved.
The implementation of step 211 is described in detail below.
As shown in fig. 4 and 5, in one embodiment, each service container group has one data interface unit, and the data interface unit of the first service container group is the first data interface unit, based on which step 211 includes:
2111. And receiving data to be transmitted sent by the first data interface unit through the first special data channel through the target storage unit. The data to be transmitted is generated by the first service container group and sent to the first data interface unit.
The first data interface unit in step 2111 may include a first data interface and a first socket interface of a protocol stack running in the first service container group, where the first socket interface is configured to receive data generated by a service program running in the first service container group, in the related art, the first socket interface will generally transmit the received data to the protocol stack running in the first service container group for further transmission processing, but in the embodiment of the present application, the first data interface is configured to hijack data sent by the first socket interface to send the data to the target storage unit of the special data processor through the first special data channel.
The data to be transmitted may be data meeting preset conditions, specifically:
in one example, any service program running in the first service container group generates initial data to be transmitted, the initial data to be transmitted is sent to the first socket interface, the first socket interface determines whether the initial data to be transmitted meets a preset condition, if yes, the initial data to be transmitted is used as data to be transmitted and sent to the first socket interface, otherwise, the initial data to be transmitted is sent to a TCP/IP layer of a protocol stack running in the first service container group, so that after the first service container group encapsulates the initial data to be transmitted, data transmission is performed through TCP connection established with the second service container group.
In another example, any service program running in the first service container group generates initial data to be transmitted, the initial data to be transmitted is sent to the first socket interface, the first socket interface sends the initial data to be transmitted to the first data interface, the first data interface determines whether the initial data to be transmitted meets a preset condition, if yes, the initial data to be transmitted is used as the data to be transmitted, otherwise, the initial data to be transmitted is returned to the first socket interface, so that the first socket interface sends the initial data to be transmitted to a TCP/IP layer of a protocol stack running in the first service container group, and after the first service container group encapsulates the initial data to be transmitted, data transmission is performed through TCP connection established with the second service container group.
The preset conditions may be set according to actual requirements, for example, the preset conditions may be: the transmission destination of the data is a second service container group, and the preset condition may be: the data is generated by a pre-specified portion of the business processes within the first business container group.
The step 2111 has the beneficial effects that the data to be transmitted generated in the first service container group can be directly placed into the target storage unit in the special data processor through the first data interface unit, so that the data transmission channel between the first service container group and the special data processor has a simple structure, the transmission flow is simplified, and the data transmission efficiency is improved.
The implementation of step 250 is described in detail below.
As shown in fig. 4 and 5, in one embodiment, the data interface unit of the second service container group is a second data interface unit, based on which step 250 includes:
step 251, send the data to be transmitted to the second data interface unit through the second dedicated data channel, so that the second data interface unit uploads the data to be transmitted to the service program running in the second service container group.
The second data interface unit in step 251 may include a second data interface and a second socket interface of a protocol stack running within a second service container group.
Specifically, in step 251, after the data to be transmitted is sent to the first virtual port, the data to be transmitted is sent to the second data interface through the second virtual port, and then the second data interface sends the data to be transmitted to the second socket interface, so that the second socket interface uploads the data to be transmitted to the service program running in the second service container group, and the service program processes according to the data to be transmitted.
In addition, the second service container group may also perform data transmission to the first service container group, and a specific process thereof is the same as a process of transmitting data to be transmitted from the first service container group to the second service container group in the embodiment of the present disclosure, which is not limited herein.
The beneficial effect of step 251 is that the data to be transmitted in the target storage unit can be directly uploaded into the second service container group through the second data interface unit, so that the data transmission channel between the second service container group and the special data processor has a simple structure, the transmission flow is simplified, and the data transmission efficiency is improved.
The implementation of step 221 is described in detail below.
As shown in fig. 4, in one embodiment, the target storage unit is a shared memory, based on which step 221 includes:
step 2211, periodically polling the shared memory to obtain the identification information of the second service container group from the data to be transmitted.
For the shared memory in step 2211, the polling frequency of the shared memory for periodic polling may be determined by the processing capability of the dedicated data processor and the data transmission amount between service container groups of the target device, where the more the processing capability of the dedicated data processor is, the higher the polling frequency is, the greater the data transmission amount between service container groups is, the lower the polling frequency is, and the polling frequency of the shared memory may be manually adjusted according to actual requirements.
The step 2211 has the beneficial effects that the shared memory of the target device and the special data processor is arranged in the special data processor instead of the target device, so that the memory resource occupation of the target device and the processing process of the target device can be reduced on the premise of ensuring the communication safety between the target device and the special data processor as much as possible, the computing resource occupation of the target device can be reduced, the data transmission speed can be improved, and the communication time delay can be reduced.
In another embodiment, as shown in fig. 5, the target storage unit is a system on a chip, based on which step 221 includes:
step 2212, acquiring identification information of a second service container group from data to be transmitted through a system on chip;
step 2213, obtaining the identification information of the second service container group sent by the system on chip.
A system-on-chip is a system-on-chip with memory and data processing capabilities.
The beneficial effects of step 2212 and step 2213 are that the embodiment of the disclosure adopts a scheme of setting a system on chip in a special data processor, and because the system on chip can directly send the received data to be transmitted to the special data processor, compared with the scheme of periodically polling the shared memory by the special data processor, the scheme of directly sending the data by the system on chip adopted in the embodiment of the disclosure can shorten the time of data communication so as to improve the data communication efficiency.
The implementation process of acquiring the identification information of the second service container group from the data to be transmitted in step 2212 and step 2213 is described in detail below.
As shown in fig. 4 and fig. 5, in one embodiment, the acquiring, in step 2211 and step 2212, identification information of the second service container group from the data to be transmitted includes:
Step 301, data identification information is obtained from the data to be transmitted, where the data identification information is used to uniquely identify the data to be transmitted, and the data identification information includes identification information of the second service container group.
Based on this, step 241 includes:
step 2411, binding the data identification information with the first virtual port information to obtain bound information;
step 2412, determining data to be transmitted in the target storage unit according to the data identification information in the bound information;
step 2413, sending the data to be transmitted from the target storage unit to the first virtual port according to the first virtual port information in the bound information.
The data identification information in step 301 may be quintuple information in the data to be transmitted, where the quintuple information of the data to be transmitted is usually located at the header of the data to be transmitted, and the quintuple information can be used to distinguish different data to be transmitted.
Specifically, in step 2411, a forwarding table may be built in a dedicated data processor, and then after the data identification information and the first virtual port information are bound to obtain bound information, the bound information is stored in the forwarding table. Wherein the forwarding table may be located in a protocol stack within the dedicated data processor. Based on this:
In step 2412, determining data to be transmitted in the target storage unit according to the data identification information in the forwarding table.
In step 2413, based on the determined data to be transmitted stored in the target storage unit, the data to be transmitted may be sent from the target storage unit to the first virtual port according to the first virtual port information in the forwarding table.
The step 301, the step 2411 to the step 2413 have the beneficial effects that, because the special data processor determines the data to be transmitted in the target storage unit according to the information after binding, and also determines the transmission destination of the data to be transmitted according to the information after binding, the special data processor can transmit a plurality of data to be transmitted at the same time, i.e. more communication processes can be processed in parallel, and the communication efficiency is improved.
