Detailed Description
The following description of the exemplary embodiments of the present application, taken in conjunction with the accompanying drawings, includes various details of the embodiments of the application for the understanding of the same, which are to be considered exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
Fig. 1 illustrates an exemplary system architecture 100 to which embodiments of the method, apparatus, electronic device, and computer-readable storage medium of the present application may be applied for establishing a data connection.
As shown in fig. 1, the system architecture 100 may include terminal devices 101, 102, 103, a network 104, and a server 105. The network 104 serves as a medium for providing communication links between the terminal devices 101, 102, 103 and the server 105. Network 104 may include various connection types, such as wired, wireless communication links, or fiber optic cables, to name a few.
The user may use the terminal devices 101, 102, 103 to interact with other terminal devices and the server 105 via the network 104 to receive or send messages or the like. The terminal devices 101, 102, 103 and the server 105 may be installed with various applications for implementing information communication therebetween, such as a co-processing application, a remote computing application, an instant messaging application, and the like.
The terminal apparatuses 101, 102, 103 and the server 105 may be hardware or software. When the terminal devices 101, 102, 103 are hardware, they may be various electronic devices with display screens, including but not limited to smart phones, tablet computers, laptop portable computers, desktop computers, and the like; when the terminal devices 101, 102, and 103 are software, they may be installed in the electronic devices listed above, and they may be implemented as multiple software or software modules, or may be implemented as a single software or software module, and are not limited in this respect. When the server 105 is hardware, it may be implemented as a distributed server cluster composed of multiple servers, or may be implemented as a single server; when the server is software, the server may be implemented as a plurality of software or software modules, or may be implemented as a single software or software module, which is not limited herein.
The server 105 may provide various services through various built-in applications, taking a remote computing application that may provide remote computing functions as an example, the server 105 may implement the following effects when running the remote computing application: receiving port scanning information sent based on a PCIE protocol from terminal devices 101, 102, and 103 serving as request terminals through a network 104, generating at least one virtual PCIE port corresponding to a port requirement included in the port scanning information, and respectively controlling each virtual PCIE port to return response information to the request terminals, and after receiving a target port connection request sent by the request terminals according to the response information, establishing data connection between the request terminals and the target virtual PCIE ports.
Since data processing usually requires more computing resources and stronger computing power, the method for establishing data connection provided in the following embodiments of the present application is generally executed by the server 105 having stronger computing power and more computing resources, and accordingly, the device for establishing data connection is generally disposed in the server 105. However, it should be noted that, when the terminal devices 101, 102, and 103 also have computing capabilities and computing resources meeting the requirements, the terminal devices 101, 102, and 103 may also complete the above-mentioned operations performed by the server 105 through the remote computing applications installed thereon, and then output the same result as the server 105
Correspondingly, the device for establishing data connection may also be disposed in the terminal devices 101, 102, and 103, so as to implement cooperative operation between different terminal devices. In such a case, the exemplary system architecture 100 may also not include the server 105 and the corresponding portion of the network 104.
It should be understood that the number of terminal devices, networks, and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation.
Referring to fig. 2, fig. 2 is a flowchart of a method for establishing a data connection according to an embodiment of the present application, where the process 200 includes the following steps:
in step 201, in response to receiving port scanning information sent by a request end based on a PCIE protocol, at least one virtual PCIE port corresponding to port requirement information included in the port scanning information is generated.
This step is intended to generate, by an execution subject (for example, the server 105 shown in fig. 1) of the method for establishing a data connection, at least one virtual port according to port requirement information included in port scanning information, after acquiring the port scanning information sent by a request end of data processing based on a PCIE protocol.
Among them, the PCIE bus is a high-speed serial replacement for the older PCI/PCI-X bus. One of the main differences between a PCIE bus and the old PCI is the bus topology. PCI uses a shared parallel bus architecture in which a PCI host and all devices share a common set of address, data, and control lines. In contrast, PCIE is based on a point-to-point topology, with separate serial links connecting each device to the root system (host). Because of its shared bus topology, the PCI bus in a single direction can be arbitrated (in the case of multiple hosts) and limited to one host at a time. Furthermore, older PCI clock schemes limited the bus clock to the slowest peripheral on the bus (regardless of the devices involved in the bus transaction). In contrast, a PCIE bus link supports full-duplex communications between any two endpoints, while concurrent access across multiple endpoints is not inherently limited.
In terms of bus protocol, PCIE traffic is encapsulated in packets. The task of packing and unpacking data and status message traffic is handled by the transaction layer of PCIE ports, and the fundamental differences in electrical signals and bus protocols require the use of different mechanical form factors and expansion connectors (and therefore, new motherboards and new adapter boards). At the software level, PCIE retains backward compatibility with PCI; traditional PCI system software can detect and configure newer PCIE devices without explicitly supporting PCIE standards, but the new PCIE functions cannot be accessed. A PCIE link between two devices may consist of 1 to 32 lanes. In a multi-lane link, packet data is striped across lanes, and peak data throughput is proportional to the overall link width. The channel count is auto-negotiated during device initialization and may be limited by either endpoint.
Further, according to the characteristics of PCIE protocol transmission, when the request end sends port scanning information to the execution main body, the request end may include corresponding port requirement information according to a data processing requirement of the request end to indicate the execution main body to determine whether there is a real PCIE port that meets the requirement information, and after receiving the port requirement information, the execution main body may generate a virtual PCIE port according to a requirement of the request end.
In some embodiments, the preset configuration information that can satisfy the processing capability and the history requirement information may also be determined according to the processing capability and the history requirement information of the request end, so as to pre-generate the virtual PCIE port through the preset configuration information, so that when port scanning information that is sent by the request end based on the PCIE protocol is received, a corresponding response is directly given, so as to improve the efficiency of the method for establishing the data connection.
It should be understood that, when the preset configuration information is determined based on the historical demand information, the preset configuration information is generally determined based on an upper limit value in the historical demand configuration information, so that the determined preset configuration information can completely meet the data processing requirement of the data request end.
It should be noted that the history requirement information may be obtained by the execution subject directly from a local storage device, or may be obtained from a non-local storage device (for example, terminal devices 101, 102, and 103 shown in fig. 1). The local storage device may be a data storage module arranged in the execution main body, such as a server hard disk, in which case the historical demand information can be quickly read locally; the non-local storage device may also be any other electronic device configured to store data, such as some user terminals, in which case the executing entity may obtain the required historical requirement information by sending a obtaining command to the electronic device.
In this embodiment, after the execution main body completes generation of the virtual PCIE ports, each virtual PCIE port is respectively controlled to send a response to the request end, so as to respond to port scanning information of the request end and inform that the request end has a corresponding "real" PCIE port, so that the request end establishes data connection after selecting a suitable "real" PCIE port.
In this embodiment, after the request end is responded by each virtual PCIE port in step 202, the request end may determine a target port according to a usage requirement and send a connection request, and after the request information received by the execution main body, correspondingly establish data connection between the request end and the target virtual PCIE port.
It should be understood that, when the request end is according to the target port sent by the response information, the execution main body determines the corresponding configuration information according to the virtual PCIE information pointed by the target port, so as to complete establishment of data connection between the request end and the target virtual PCIE port.
In the method for establishing data connection provided in the embodiment of the present application, after responding to receiving port scanning information sent by a request end based on a PCIE protocol, at least one virtual PCIE port corresponding to port requirement information included in the port scanning information is generated, and each virtual PCIE port is respectively controlled to return response information to the request end, and after responding to receiving a target port connection request sent by the request end according to the response information, data connection between the request end and a target virtual PCIE port is established. According to the method and the device, the PCIE port configuration can be dynamically realized, so that the adaptive configuration is carried out on the scanning information of the request terminal, the flexibility of a data receiving terminal system is improved, and the design cost is reduced.
In some optional implementation manners of this embodiment, generating at least one virtual PCIE port corresponding to the port requirement information included in the port scanning information includes: extracting port requirement information contained in the port scanning information from the port scanning information; and generating a virtual PCIE port meeting the quantity requirement and the performance requirement according to the quantity requirement and the performance requirement of the target port in the port requirement information.
Specifically, when port scanning information sent by a request end is acquired, a reasonable configuration proportion is determined according to the corresponding port quantity requirement and performance requirement, distributable performance parameters of a local execution main body or a receiving end to be configured are acquired, and a virtual PCIE port meeting the quantity requirement and the performance requirement is generated according to the configuration proportion, so that the virtual PCIE port is determined according to port requirement information in the scanning information in a matching manner, and waste of data processing resources is avoided.
Referring to fig. 3, fig. 3 is a flowchart of another method for establishing a data connection according to an embodiment of the present application, and in addition, to describe a process of generating configuration parameters of a control panel more clearly, fig. 4 is an interactive flowchart of a request end, an execution main body, and the control panel according to the embodiment, where the process 300 includes the following steps:
In this embodiment, reference may be made to step 401 in fig. 4.
In this embodiment, reference may be made to step 402 in fig. 4.
In this embodiment, reference may be made to steps 403 and 404 in fig. 4.
In this embodiment, after the data connection between the request end and the target virtual PCIE port is established in step 303, a to-be-processed data Packet sent by the request end to the target virtual PCIE port based on the PCIE protocol is obtained, where the to-be-processed data includes port direction information for directing and determining the target virtual PCIE port, and an object Layer Packet (TLP for short) containing the to-be-processed data, which may be referred to as steps 406 and 407 in fig. 4 correspondingly.
In this embodiment, the port direction information is sent to the control panel, the control panel is configured to process the space configuration of the receiving end device, the bus and the configuration request of the request end, and drive the local control of the request end, after the port direction information is obtained, the control panel may determine the corresponding processing space and the configuration parameters according to the port direction information, so that the data processing panel performs corresponding data processing according to the configuration parameters, which may refer to steps 408 and 409 in fig. 4.
In this embodiment, after the TLP is directly acquired in the step 304, the content is directly sent to the data processing panel, and the data processing panel performs corresponding data processing according to the configuration parameters generated in the step 305 after receiving the TLP, so as to obtain a corresponding processing result.
In practice, when data transmission and processing are performed based on the PCIE protocol, the data processing panel is generally used for group data transmission (Direct Memory accesses, DMA for short) operations and interrupt operations.
In some embodiments, after the data processing panel obtains the configuration parameter, the data processing panel may also instruct, according to the specific direction and the control content of the configuration parameter, other execution bodies, operation modules, and the like to execute corresponding operations, which is not limited in this application.
The above steps 301-303 are the same as the step 201-203 shown in fig. 2, and the contents of the same portions refer to the corresponding portions of the previous embodiment, which are not described herein again.
On the basis of the method for establishing data connection provided in the embodiment shown in fig. 2, the present embodiment further provides a specific manner for processing the data at the request end, so as to implement virtual parameter configuration through software allocation of the control panel, and instruct the processing panel that directly obtains data information in the data to be processed through hardware design to perform corresponding processing, so that in a manner of combining software and hardware, on the premise of ensuring data processing quality, data processing efficiency is improved, and design cost is saved.
In some optional implementations of this embodiment, the method further includes:
Specifically, after the data processing panel in step 306 completes the data processing of the TLP, the execution body may obtain a data processing result generated in the data processing panel, and merge the port direction information with the data processing result, so as to mark the data processing result through the port direction information, and generate a data feedback result.
In the process of marking the data processing result by the port direction information, usually, the mark identifier generated by the port direction information is used to notify the request end of the relevant configuration information of the data sending port, that is, the configuration information of the PCIE port requested by the request end is generated based on the configuration information of the target virtual port PCIE, so that the request end considers that the data feedback result is sent by the actually existing real PCIE port.
In addition, a corresponding header, a corresponding password, and the like may be generated according to the port direction information, so that the requesting end of the data processing may identify and confirm the obtained data processing result according to the header, the password, and the like marking contents generated by the port direction information.
In practice, in order to further save the setting cost at the hardware level, the physical hardware for combining the port direction information and the data processing result in this implementation may be set together with the physical hardware for decomposing the to-be-processed data packet into the port direction information and the data information in step 304.
In some optional implementation manners of this embodiment, in order to further implement data cooperative processing between a request end and a receiving end based on a PCIE protocol and improve a data processing effect, when the data request end issues a data processing request, only an operation instruction expected to be executed by the data receiving end and corresponding address information may be issued, and in this case, the step of controlling the processing panel to perform data processing according to the configuration parameter includes: controlling the processing panel to start DMA reading operation by adopting the configuration parameters; and controlling the processing panel to send a DMA read request to the request end and receive response data corresponding to the DMA read request to perform data processing.
Specifically, the data plane mainly processes DMA operations and start instructions and interrupt operations issued by the request side. The control panel simulates that information such as queues, addresses, parameters and the like issued by a request end is configured to the data panel, when the request end issues a starting instruction, the data panel starts DMA operation, and writes the receiving end equipment data into the memory specified by the execution main body or reads the data from the memory specified by the request end to the execution main body.
In practice, after the data panel completes the DMA write request, an interrupt TLP packet is sent to the requesting end, so as to achieve the interrupt purpose.
