The symbol "/" generally indicates that the former and latter associated objects are in an "or" relationship.
Before describing the embodiments of the present invention, first, terms related to the embodiments of the present invention will be described.
The virtual accelerator comprises one or more virtualized accelerators simulated through network function virtualization, and the virtual accelerators can be arranged on the computer and the like and are used for realizing a data acceleration function on the computer and the like. The virtual accelerator is not used for accelerating data substantially, but is used for data transmission with the physical accelerator, and the physical accelerator actually realizes data acceleration. However, for applications on a computer or other device, the virtual accelerator may perform data acceleration functions just like a real accelerator.
The physical accelerator is used for really realizing a data acceleration function, and can be a field-programmable gate array (FPGA), an accelerator array and other devices with acceleration capability on physical hardware. The physical accelerator may bind with the virtual accelerator to accelerate data sent by the virtual accelerator or to send accelerated data to the virtual accelerator.
And the acceleration network channel is used for connecting the virtual accelerator and the physical accelerator when the virtual accelerator and the physical accelerator are not in the same device, and providing a network channel for data transmission for the virtual accelerator and the physical accelerator.
Fig. 1 is a schematic structural diagram of a Network Function Virtualization (NFV) system according to an embodiment of the present invention. Referring to fig. 1, the NFV system includes at least one device 101 and a management and orchestrator (MANO) 102. In fig. 1, at least one device 101 is illustrated as including a first device 1011 and a second device 1012.
The first device 1011 and the second device 1012 belong to NFV infrastructure (NFVI), and may be used to provide hardware resources and virtualized resources for a Virtualized Network Function (VNF) 103, and to manage the hardware resources and the virtualized resources, and to provide a virtualized operating environment. The distributed deployment of acceleration agents on each device is under the overall control of the acceleration controllers in the MANO 102. The physical accelerator is used for realizing the acceleration function of the business data. At least one device 101 is communicatively coupled to the infrastructure orchestrator and the devices via a network.
As shown in fig. 2, a schematic diagram of a specific acceleration framework in at least one device 101, the acceleration framework includes an application layer 111 and an acceleration layer 112. It will be understood by those skilled in the art that fig. 2 illustrates an example where the first device includes a physical accelerator and the second device includes a virtual accelerator, and fig. 2 does not limit the acceleration framework of the embodiment of the present invention.
The application layer 111 includes a client application layer and a host application layer. The client application layer is an NFV-based application layer for providing a virtualized network function VNF. The host application layer is an application layer established on the operating system of the device itself, and is used to provide network services and the like for the device. The client application layer and the host application layer may respectively include at least one application program, and an acceleration Software Development Kit (SDK) and a virtual accelerator driver (vAE driver) corresponding to the at least one application program.
The acceleration layer 112 may include a plurality of acceleration modules, represented in FIG. 2 by pAE. The acceleration module may be composed in various ways, for example, the acceleration module may include a virtual accelerator and a physical accelerator, or the acceleration module may include a virtual accelerator or a physical accelerator, the virtual accelerator being denoted by vAE in fig. 2, and the physical accelerator being denoted by sAE. The virtual accelerator is used for configuring an interface for an application program, and the virtual accelerator needs to bind the physical accelerator to realize the acceleration function of data. The virtual accelerator may be directly or indirectly connected with the physical accelerator, and the direct or indirect connection may be statically or dynamically orchestrated by the acceleration controller. When the virtual accelerator is indirectly connected to the physical accelerator, it may be connected through a network accelerator, represented in FIG. 2 as nAE. The network accelerator is used for providing a network acceleration channel for the virtual accelerator and the physical accelerator, namely providing a far-end acceleration network and a bearer layer function, and a peer-to-peer protocol stack is arranged at two ends of the virtual accelerator and the physical accelerator and has all attributes (such as addressing, link, bandwidth, QoS and the like) of network hardware.
In addition, the application program of the client application layer can access the acceleration layer through a through access mode or a virtual bus access mode to realize acceleration of data to be accelerated. The pass-through access mode refers to that an application program of a client application layer directly accesses an acceleration layer through a bus, for example, the bus may be a peripheral component interconnect express (PCIe) bus. Virtual access mode refers to the application program of the client application layer accessing the backend vAE driven management through a virtual bus (such as virtual PCI), and accessing the acceleration layer through the bus driven management by the backend vAE. Among other things, the back end vAE driver management is used to manage and orchestrate virtual access interface resources and the like. The application of the host application layer may be connected to the acceleration layer via a bus, which may be PCIe, for example.
Fig. 3 is a flowchart of a data acceleration method according to an embodiment of the present invention, which is applied in the NFV system, and referring to fig. 3, the method includes the following steps.
Step 201: the virtual accelerator receives first data to be accelerated.
Wherein the virtual accelerator may be located on at least one device in the NFV system, and one device may include one or more virtual accelerators thereon. The application layers of the at least one device may include a client application layer and a host application layer, and the client application layer and the host application layer may include at least one application program, respectively. Each application may correspond to a virtual accelerator, or multiple applications may correspond to a virtual accelerator, or an application may correspond to multiple virtual accelerators.
When an application program in at least one application program needs to perform data acceleration, the application program may send first data to be accelerated to a corresponding virtual accelerator, so that the virtual accelerator receives the first data to be accelerated.
Step 202: the virtual accelerator sends an acceleration request message to the physical accelerator; the acceleration request message includes first data to be accelerated, and is used for instructing the physical accelerator to accelerate the first data to be accelerated.
The NFV system may include at least one physical accelerator, and one virtual accelerator may correspond to one physical accelerator, or correspond to multiple physical accelerators, or correspond to one physical accelerator among multiple virtual accelerators.
When the virtual accelerator receives the first data to be accelerated sent by the application program, the virtual accelerator may send an acceleration request message including the first data to be accelerated to the corresponding physical accelerator, so that the physical accelerator accelerates the first data to be accelerated when receiving the acceleration request message.
In practical applications, the acceleration request message may further include some acceleration-related information, which is related to the acceleration type of the first data to be accelerated. The acceleration type may include IP security (IPsec), Service Awareness (SA), GPRS Encryption Algorithm (GEA), service data acceleration, and the like. Specifically, when the acceleration type is IPsec, the acceleration related information may be an encryption/decryption type (encryption or decryption), an algorithm type, a key, an initialization vector (english: initialization vector, abbreviated as IV), and the like; when the acceleration type is SA, the acceleration related information can be divided into information such as an analysis rule, an analysis result storage position and the like; when the acceleration type is the GEA, the acceleration related information can be information such as an encryption and decryption type, a key, a data length and the like; when the acceleration type is service acceleration data, the information related to acceleration may include service-defined data and a rule that needs acceleration, and this part may be adjusted accordingly according to the service acceleration data.
Step 203: when the physical accelerator receives the acceleration request message, the physical accelerator accelerates the first data to be accelerated to obtain first target data.
When the physical accelerator receives an acceleration request message sent by the virtual accelerator, the physical accelerator may accelerate the first data to be accelerated according to the acceleration request message to obtain the first target data.
Specifically, when the acceleration type is IPSec, the physical accelerator may perform corresponding encryption and decryption on data by using a key, an IV, and the like according to the encryption and decryption type and the algorithm type. When the acceleration type is SA, the physical accelerator may parse the data according to the parsing rule, and place the result in an agreed location after parsing. When the acceleration type is SA, the physical accelerator may perform corresponding encryption and decryption on the data of the specified length by using the key according to the encryption and decryption type. When the acceleration type is service data acceleration, the physical accelerator can perform corresponding acceleration analysis according to rule information issued by the service, and store the result according to the rule. The acceleration capability of the physical accelerator corresponding to the acceleration types can reach XX Gbps (gigabits per second) or XX MPPS (mega packets per second).
In the embodiment of the present invention, if an application program in the NFV system needs to perform data acceleration, the application program may send first data to be accelerated to a virtual accelerator, and when the virtual accelerator receives the first data to be accelerated, the virtual accelerator sends an acceleration request message including the first data to be accelerated to a physical accelerator, so that the physical accelerator can accelerate the first data to be accelerated when receiving the first data to be accelerated, thereby implementing a data acceleration function in the NFV system through the virtual accelerator, and further improving data processing efficiency.
Further, after the physical accelerator obtains the first target data according to the step 201 and 203, if the first target data is data sent to an external network, the physical accelerator may directly send the first target data through the network interface; if the first target data is data that needs to be returned to the application, the physical accelerator may return the first target data to the application that sent the first data to be accelerated.
Referring to fig. 4, if the first target data is data that needs to be returned to the application, after step 203, the method further comprises: step 204-step 205.
Step 204: the physical accelerator sends the first target data to the virtual accelerator.
Step 205: when the virtual accelerator receives the first target data sent by the physical accelerator, the virtual accelerator sends the first target data.
If the first target data is data that needs to be returned to the application, the physical accelerator may send the first target data to the virtual accelerator after obtaining the first target data. When the virtual accelerator receives the first target data, the virtual accelerator may return the first target data to the application that sent the first data to be accelerated.
In the embodiment of the present invention, after the physical accelerator performs data acceleration on the first data to be accelerated to obtain the first target data, the physical accelerator may send the first target data out through the network interface or directly return the first target data to the application program, thereby implementing a data acceleration function for the application program and a data acceleration function for the downlink data in the NFV system, and further improving data processing efficiency.
Further, as shown in fig. 5 and fig. 6, the virtual accelerator and the physical accelerator may be located in the same device included in the NFV system, or may be located in different devices included in the NFV system. The NFV system may include a first device, and the virtual accelerator vAE and the physical accelerator sAE may be located in the first device, for example, the first device may be device 1 shown in fig. 5. Alternatively, the NFV system may include a first device and a second device, the virtual accelerator vAE may be located in the first device, and the physical accelerator sAE may be located in the second device, for example, the first device may be device 2 shown in fig. 6, and the second device may be device 3 shown in fig. 6.
When the NFV includes the first device, and the virtual accelerator and the physical accelerator are located in the first device, the virtual accelerator and the physical accelerator may accelerate the first data to be accelerated directly through the steps 201 and 203 or the steps 201 and 205.
When the NFV system includes a first device and a second device, the virtual accelerator is located in the first device, and the physical accelerator is located in the second device, then step 202 may specifically be: the virtual accelerator sends an acceleration request message to the physical accelerator over an acceleration network channel. The virtual accelerator and the physical accelerator are connected through an acceleration network channel. For example, as shown in the acceleration framework of fig. 6, if the virtual accelerator vAE in the device 2 sends an acceleration request message to the physical accelerator sAE in the device 3, the virtual accelerator vAE in the device 2 may send the acceleration request message to the physical accelerator sAE in the device 3 through a data transmission channel between the network accelerator nAE in the device 2 and the network accelerator nAE in the device 3.
Correspondingly, step 204 may specifically be: the physical accelerator sends the first target data to the virtual accelerator through the acceleration network channel. For example, as shown in the acceleration framework of fig. 6, if the physical accelerator sAE in the device 3 sends the first target data to the virtual accelerator vAE in the device 2, the physical accelerator sAE in the device 3 may send the first target data to the virtual accelerator vAE in the device 2 through a data transmission channel between the network accelerator nAE in the device 3 and the network accelerator nAE in the device 2.
In the embodiment of the invention, when the virtual accelerator and the physical accelerator are not in the same device, the virtual accelerator and the physical accelerator realize the function of accelerating the transmission data through the acceleration network channel, so that under the condition that other devices do not have the physical accelerator, the data to be accelerated can be accelerated, and the acceleration resources are saved.
Further, referring to fig. 7, before step 201, the method further includes step 200.
Step 200: the virtual accelerator receives acceleration configuration information that indicates the virtual accelerator to accelerate data through the physical accelerator.
Wherein the acceleration configuration information may be sent by the acceleration controller to the virtual accelerator. The acceleration controller may be the acceleration controller in the NFV system described above in fig. 1, and the acceleration controller may be a device having a management function in a MANO.
When the NFV system includes at least one virtual accelerator and at least one physical accelerator, the acceleration controller may be configured to manage a binding relationship of the at least one virtual accelerator and the at least one physical accelerator. The acceleration controller may send acceleration configuration information to the virtual accelerator, where the acceleration configuration information may be used to indicate which physical accelerator of the at least one physical accelerator the virtual accelerator is to accelerate data through. For example, in the acceleration framework shown in fig. 6, the acceleration controller may send acceleration configuration information to the virtual accelerator vAE in device 2, which may be used to instruct the virtual accelerator to accelerate data through the physical accelerator sAE in device 3.
Specifically, when the virtual accelerator and the physical accelerator are in the same device (such as device 1 in fig. 5), the acceleration controller may or may not send the acceleration configuration information to the virtual accelerator in the device. When the acceleration controller does not send acceleration configuration information to the virtual accelerator in the device, the virtual accelerator may perform data acceleration directly through the physical accelerator in the device.
When the virtual accelerator and the physical accelerator are not in the same device (such as device 2 and device 3 in fig. 6), the acceleration controller may send acceleration configuration information to the device including the virtual accelerator for indicating the binding relationship of the virtual accelerator and the physical accelerator. Optionally, when the acceleration controller sends the acceleration configuration information to the virtual accelerator, a device in which the virtual accelerator is located may include an acceleration agent, and the acceleration controller may send the acceleration configuration information to the acceleration agent, and the acceleration agent forwards the acceleration configuration information to the virtual accelerator.
Optionally, the acceleration controller may also send acceleration indication information to the physical accelerator, where the acceleration indication information is used to instruct the physical accelerator to provide a data acceleration function for the virtual accelerator. The process of sending the acceleration indication information to the physical accelerator by the acceleration controller may be similar to the process of sending the acceleration configuration information to the virtual accelerator by the acceleration controller, which specifically refers to the description of sending the acceleration configuration information to the virtual accelerator by the acceleration controller, and is not described herein again in the embodiments of the present invention.
In the embodiment of the invention, the acceleration controller can reasonably bind the virtual accelerator and the physical accelerator by sending the acceleration configuration information, so that when the virtual accelerator performs data acceleration, the data to be accelerated is sent to the corresponding physical accelerator to realize the function of data acceleration, thereby improving the utilization rate of acceleration resources and the efficiency of data acceleration.
Fig. 8 is a flowchart of a data acceleration method according to an embodiment of the present invention, which is applied in the NFV system, and referring to fig. 8, the method includes the following steps.
Step 301: and when the physical accelerator receives the second data to be accelerated through the network interface, the physical accelerator accelerates the second data to be accelerated to obtain second target data.
The NFV system comprises a virtual accelerator and at least one device, and one or more virtual accelerators can be included on one device. The application layers of the at least one device may include a client application layer and a host application layer, and the client application layer and the host application layer may include at least one application program, respectively. Each application may correspond to a virtual accelerator, or multiple applications may correspond to a virtual accelerator, or an application may correspond to multiple virtual accelerators.
The second data to be accelerated may be data to be accelerated transmitted to the application program by the external network, and when the physical accelerator receives the second data to be accelerated transmitted by the external network through the network interface, the physical accelerator may accelerate the second data to be accelerated, so as to obtain second target data.
Step 302: the physical accelerator sends the second target data to the virtual accelerator.
The NFV system may include at least one physical accelerator, and one virtual accelerator may correspond to one physical accelerator, or correspond to multiple physical accelerators, or correspond to one physical accelerator among multiple virtual accelerators. After the physical accelerator accelerates the second data to be accelerated to obtain second target data, the physical accelerator may send the second target data to the corresponding virtual accelerator.
In practical applications, when the physical accelerator sends the second target data to the physical accelerator, the physical accelerator may also send some acceleration related information to the virtual accelerator. The acceleration-related information may be similar to the acceleration-related information in step 202 of the foregoing embodiment, and refer to the explanation in step 202 specifically, which is not described herein again in the embodiment of the present invention.
Step 303: when the virtual accelerator receives the second target data sent by the physical accelerator, the virtual accelerator sends the second target data.
When the virtual accelerator receives the second target data sent by the physical accelerator, the virtual accelerator may send the second target data to the corresponding application program for use by the application program.
In the embodiment of the present invention, if data acceleration is required for received data of an external network in an NFV system, when a physical accelerator receives second data to be accelerated through a network interface, the physical accelerator may perform data acceleration on the second data to be accelerated to obtain second target data, send the second target data to a virtual accelerator, and send the second target data to a corresponding application program through the virtual accelerator, thereby implementing data acceleration on uplink data in the NFV system through the physical accelerator and the virtual accelerator, and further improving data processing efficiency.
Further, as shown in fig. 5 and fig. 6, the virtual accelerator and the physical accelerator may be located in the same device included in the NFV system, or may be located in different devices included in the NFV system. The NFV system may include a first device, and the virtual accelerator vAE and the physical accelerator sAE may be located in the first device, for example, the first device may be device 1 shown in fig. 5. Alternatively, the NFV system may include a first device and a second device, the virtual accelerator may be located in the first device, and the physical accelerator may be located in the second device, for example, the first device may be device 2 shown in fig. 6, and the second device may be device 3 shown in fig. 6.
When the NFV system includes a first device and a second device, the virtual accelerator is located in the first device, and the physical accelerator is located in the second device, step 302 may specifically be: the physical accelerator sends the second target data to the virtual accelerator through the acceleration network channel. The virtual accelerator and the physical accelerator are connected through an acceleration network channel.
For example, as shown in the acceleration framework of fig. 6, if the physical accelerator sAE in the device 3 sends the second target data to the virtual accelerator vAE in the device 2, the physical accelerator sAE in the device 3 may send the second target data to the virtual accelerator vAE in the device 2 through a data transmission channel between the network accelerator nAE in the device 3 and the network accelerator nAE in the device 2. The second target data is then sent by the virtual accelerator vAE to the corresponding application.
In the embodiment of the invention, when the virtual accelerator and the physical accelerator are not in the same device, the virtual accelerator and the physical accelerator realize the data transmission acceleration function through the acceleration network channel, so that under the condition that other devices do not have the physical accelerator, the data acceleration of the data to be accelerated can be realized, and the utilization rate of the acceleration resources is improved.
Further, referring to fig. 9, before step 301, the method further includes step 300.
Step 300: the virtual accelerator receives acceleration configuration information that indicates the virtual accelerator to accelerate data through the physical accelerator.
Wherein the acceleration configuration information may be sent by the acceleration controller to the virtual accelerator. The acceleration controller may be the acceleration controller in the NFV system described above in fig. 1, and the acceleration controller may be a device having a management function in a MANO.
When the NFV system includes at least one virtual accelerator and at least one physical accelerator, the acceleration controller may be configured to manage a binding relationship of the at least one virtual accelerator and the at least one physical accelerator. The acceleration controller may send acceleration configuration information to the virtual accelerator, where the acceleration configuration information may be used to indicate which physical accelerator of the at least one physical accelerator the virtual accelerator is to accelerate data through. Specifically, the process of configuring the binding relationship between the virtual accelerator and the physical accelerator by the acceleration controller is consistent with step 200 in the foregoing embodiment, and specific reference to the description in step 200 is not repeated here.
In the embodiment of the invention, the acceleration controller can reasonably bind the virtual accelerator and the physical accelerator by sending the acceleration configuration information, so that when the virtual accelerator performs data acceleration, the data to be accelerated is sent to the corresponding physical accelerator to realize the function of data acceleration, thereby improving the utilization rate of acceleration resources and the efficiency of data acceleration.
