Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Virtualization is a key ring of a cloud computing infrastructure, and the number of physical servers can be effectively reduced. Virtualization saves space occupied by a data center and operation overhead by efficiently integrating a physical infrastructure and an application program. Through the virtualization technology, a plurality of virtual machines can be generated on one physical server, and comprehensive isolation can be realized among the virtual machines. And the user acquires resources on the cloud computing through the virtual machines.

In recent years, due to the increase of network function virtualization (nfv) (network Functions virtualization) applications on the cloud, the requirements of users on network performance are also continuously increased, and with the gradual popularization of 100G network cards, the performance and bandwidth of the network card are continuously improved, although a Central Processing Unit (CPU) and a Network Interface Controller (NIC), which may also be referred to as a network card, provide several mechanisms to improve the efficiency of I/O (Input/Output) processing, for example, directly introduce data into a CPU LLC (Last layer Cache), and improve expandability by reducing Cache contention among CPU cores and reducing interrupt frequency. However, even with these enhanced functions, pure software forwarding cannot meet the increasing network demands, and only the number of CPUs is increased continuously for network forwarding.

If DPDK (Data Plane Development Kit) PMD (Poll Mode Driver) is used at both the front and back ends of the cloud, and only the simplest forwarding is performed. To achieve true zero packet loss, the single core forwarding performance is only 2.17 mbps (packets per second), and this also requires very deep code tuning and extensive system and configuration optimization. Furthermore, if a small amount of other processing is added to the forwarding logic, a significant degradation in forwarding performance may result. It is therefore a very challenging task to implement high performance forwarding with pure software, even if there is enough CPU resources.

The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.

Fig. 1A is a schematic structural diagram of a data transmission system according to an exemplary embodiment of the present application. As shown in fig. 1A, the transmission system 100A may include: a first device 101 and a second device 102.

The first device 101 may be a device with certain computing capability, and may implement a function of sending transmission data to the second device 102, where the transmission data may belong to data to be transmitted for the second device 102. This transmission of data may require some data processing by the second device 102. The basic structure of the first device 101 may include: at least one processor. The number of processors may depend on the configuration and type of device with a certain computing power. A device with certain computing capabilities may also include Memory, which may be volatile, such as RAM, non-volatile, such as Read-Only Memory (ROM), flash Memory, etc., or both. The memory typically stores an Operating System (OS), one or more application programs, and may also store program data and the like. In addition to the processing unit and the memory, the device with certain computing capabilities also includes some basic configurations, such as a network card chip, an IO bus, a display component, and some peripheral devices. Alternatively, some peripheral devices may include, for example, a keyboard, a stylus, and the like. Other peripheral devices are well known in the art and will not be described in detail herein. Alternatively, the first device 101 may be a smart terminal, such as a mobile phone, a desktop computer, a notebook, a tablet computer, and the like.

The second device 102 refers to a device that can provide a computing processing service in a network virtual environment, and may refer to a device that performs data transmission and data processing using a network. In physical implementation, the second device 102 may be any device capable of providing computing services, responding to service requests, and performing data processing, and may be, for example, a cloud server, a cloud host, a virtual center, a regular server, and the like. The second device 102 mainly includes a processor, a hard disk, a memory, a system bus, and the like, and is similar to a general computer architecture.

In this embodiment, the first device 101 sends transmission data to be processed to the second device 102; the second device 102 receives the transmission data (for the second device 102, the transmission data is also data to be transmitted), and sends the transmission data to a corresponding virtual device in the second device 102 through forwarding hardware in the transmission device.

After receiving the transmission data, the virtual device may perform data processing on the transmission data, send the processed data to the forwarding hardware, and return the processed data to the first device 101 through the forwarding hardware.

In addition, based on the system 100A, an exemplary embodiment of the present application further provides a schematic structural diagram of a data transmission system. As shown in fig. 1B, the transmission system 100B may include: a first device 101, a second device 102 and a third device 103.

Since the first device 101 and the second device 102 have been described in detail above, they are described in detail here.

Wherein the third device 103 is similar to the second device 102. The third device 103 may also be a device that can provide a computing processing service in a network virtual environment, and may be a device that performs data transmission and data processing using a network. In physical implementation, the third device 103 may be any device capable of providing computing services, responding to service requests, and performing data processing, and may be, for example, a cloud server, a cloud host, a virtual center, a regular server, and the like. The third device 103 mainly includes a processor, a hard disk, a memory, a system bus, and the like, and is similar to a general computer architecture.

Based on the description in the system 100A, after receiving the transmission data, the virtual device in the second device 102 may send the transmission data (for the third device 103, the transmission data may also be data to be transmitted) to the third device 103 through forwarding hardware in the process of processing the data. The transmission device in the third device 103 receives the transmission data, and the forwarding hardware in the transmission device sends the transmission data to the corresponding virtual device, and the virtual device performs data processing on the transmission data and returns the processed data to the corresponding virtual device of the second device 102 in an original path, so that the corresponding virtual device of the second device 102 performs data processing based on the received processed data and returns the processed data to the first device 101.

In addition, as for the third device 103, the third device 103 may also have no virtual device and forwarding hardware, and after the transmission device of the third device 103 receives the transmission data, the third device 103 itself may directly perform data processing on the received transmission data, and return the data processing result to the second device 102.

The number of devices involved in each of the systems may be plural. E.g. a plurality of different first devices 101 accessing one or more different second devices 102, etc.

In an application scenario of the embodiment of the application, a user stores a video file to a second device 102, such as a cloud server, through a first device 101, such as a computer. The user accesses the web network interface of the second device 102 providing the storage service through the browser installed in the first device 101. The first device 101, in response to an operation of storing a video file by a user, acquires the video file as transmission data (i.e., data to be transmitted), and sends the video file to a transmission device, such as a network card, of the second device 102. After receiving the video file, the transmission device sends the video file to forwarding hardware inside the transmission device, such as a Field Programmable Gate Array (FPGA), or, directly receives the video file by the FPGA in the network card, queries a forwarding path of the video file through the forwarding hardware, and sends the video file to a virtual device, such as a virtual machine, in the second device 102 according to the forwarding path, so as to store the file. After the virtual device stores the video file, the information that the video is successfully stored may be forwarded to the first device 101 through forwarding hardware, so that the first device 101 receives the information and displays the information to the user through a web interface.

In addition, when the forwarding hardware cannot find the forwarding path of the video file, the video file is uploaded to a virtual forwarding device, such as a virtual switch, where the virtual forwarding device may be set on a network card, that is, a software virtual forwarding device running on a CPU of the network card, or the virtual forwarding device may also be set on the second device 102, that is, a software virtual forwarding device running on a CPU of a cloud server. And the first layer of virtual forwarding equipment in the virtual forwarding equipment receives the video file, determines a forwarding path of the video file, and sends the video file to the corresponding virtual equipment according to the forwarding path.

When the first layer of virtual forwarding equipment can not determine the forwarding path, the first layer of virtual forwarding equipment uploads the video file to a second layer of virtual forwarding equipment in the virtual forwarding equipment, and the second layer of virtual forwarding equipment determines the forwarding path and sends the video file to the corresponding virtual equipment.

In addition, the user may also obtain files from the second device 102 through the first device 101. The first device 101 sends an acquisition request to the second device 102, the second device 102 sends the acquisition request to a corresponding virtual device through forwarding hardware, and the virtual device can acquire a file corresponding to the acquisition request from the third device 103 based on the acquisition request. The process of acquiring the file is similar to the process of sending data from the first device 101 to the second device, and is not described herein again. After receiving the file, the virtual device corresponding to the second device 102 returns the file to the first device 101.

It should be noted that the system may also be applied to other scenarios, for example, website building, cloud service selling, and the like, which is not described in detail herein.

In the present embodiment described above, the first device 101, the second device 102, and the third device 103 perform network connection, which may be wireless connection. If the first device 101, the second device 102, and the third device 103 are communicatively connected, the network format of the mobile network may be any one of 2G (gsm), 2.5G (gprs), 3G (WCDMA, TD-SCDMA, CDMA2000, UTMS), 4G (LTE), 4G + (LTE +), WiMax, 5G, and the like.

The following describes the data transmission process in detail with reference to the method embodiment.

Fig. 2 is a flowchart illustrating a data transmission method according to an exemplary embodiment of the present application. The method 200 provided by the embodiment of the present application is executed by a computing device, that is, the second device 102 is executed, for example, a cloud server. The computing device includes a transmitting device including forwarding hardware and at least one virtual device. The method 200 comprises the steps of:

201: and receiving data to be transmitted between the at least one virtual device and the external device through the forwarding hardware.

202: and determining a forwarding path of the data to be transmitted through forwarding hardware.

203: and sending out the data to be transmitted according to the forwarding path through forwarding hardware.

The following is detailed for the above steps:

The forwarding hardware refers to forwarding hardware with processing capability, and the hardware can forward data, wherein the data can be transmitted in a message form. The hardware may be an editable electronic device with processing function, such as an FPGA, an Integrated Circuit with processing function, such as an ASIC (Application Specific Integrated Circuit), or an editable chip with processing function, such as a TOFINO dofnol chip.

It should be understood that each type of forwarding hardware may implement the logic of the forwarding function through programmed logic.

A virtual device refers to a device that relies on a computing device (e.g., a physical server, a cloud server, etc.) to create an independent operating environment. Such as a virtual machine. May be created on a computing device through virtual techniques. The virtual device may also be a container docker, where the computing device supports, e.g., the computing device may provide multiple transport devices.

The external device refers to a device other than the computing device, and performs network communication with the virtual device in the computing device. Such as the user's computer.

For example, according to the foregoing, a computer of a user sends a video file to a cloud server for storage through a network, and the cloud server receives the video file through a network card configured in the cloud server. After the network card receives the video file, the video file is determined to be sent to a certain virtual machine on the cloud server, and the video file can be sent to FPGA forwarding hardware.

In addition, when at least one virtual machine on the cloud server needs to send a message to the computer of the user, the virtual machine sends the message to the FPGA forwarding hardware, the FPGA forwarding hardware sends the message to the computer of the user through the network card.

It should be noted that the forwarding hardware may be disposed in a transmission device, and the transmission device may perform a network transmission function, such as a physical network card, an intelligent network card, and so on. The forwarding hardware may also exist independently, is not arranged in the network card, but may be connected with the network card to further complete the forwarding function, and at this time, the transmission device may be directly the forwarding hardware, such as an FPGA.

The forwarding path refers to information that the data to be transmitted needs to send a destination next time, and may be recorded through a flow table, where multiple forwarding paths may be recorded in the flow table, and each forwarding path may also be referred to as a flow direction of one data, or a flow. In the forwarding hardware, the forwarding hardware cannot support the forwarding of all paths due to the limitation of hardware resources, and the forwarding hardware needs to forward the supportable forwarding paths according to the hardware resources.

Some information such as matching fields, action sets, and counters may be recorded in each forwarding path. The matching field may have address information, such as a source address, for matching information carried by the data to be transmitted, and after matching is successful, the forwarding action may be executed according to the action in the action set, so that the counter may count once.

The method for determining the forwarding path of the data to be transmitted may include: matching data to be transmitted with at least one forwarding path in forwarding hardware; and determining the matched forwarding path under the matching result.

The matching of the data to be transmitted and at least one forwarding path in the forwarding hardware includes: and matching the field data in the data to be transmitted with the corresponding field data in at least one forwarding path. It should be understood that this field data is the match field described above.

For example, according to the foregoing, after receiving a video file, an FPGA (i.e., FPGA forwarding hardware), the FPGA sends the video file in the form of a message, and the FPGA analyzes the message to obtain matching fields carried by the message, such as source address information and identification information pointing to a virtual device. When the matching field of the message is the same as the matching field in any forwarding path recorded in the flow table in the FPGA, the matching forwarding path can be determined.

For example, according to the foregoing, after the FPGA determines that there is a matching forwarding path, the FPGA may forward the video file to the corresponding virtual machine according to the forwarding action in the forwarding path.

Under the condition that the external device sends data to at least one virtual device, sending the data to be transmitted according to a forwarding path through forwarding hardware, the method comprises the following steps: determining corresponding virtual equipment according to a forwarding path through forwarding hardware; and sending the data to be transmitted to the virtual equipment through forwarding hardware.

For example, according to the foregoing, after the FPGA determines that there is a matching forwarding path, the FPGA may determine the virtual machine according to the identifier pointing to the corresponding virtual machine recorded in the forwarding path, so as to send the video file to the corresponding virtual machine.

It should be noted that, when the virtual device sends the data to be transmitted to the external device, the process is similar to or the reverse process of sending the data to be transmitted from the external device to the virtual device, and details are not described here. It should be understood that when the virtual device, for example, a virtual machine, sends data to be transmitted to the FPGA to determine a forwarding path, so as to implement forwarding.

Specifically, determining, by the forwarding hardware and according to the forwarding path, the corresponding virtual device may include: determining, by forwarding hardware, a first virtual transmission device according to a virtual transmission identifier in a forwarding path, the first virtual transmission device being created based on a transmission device; and determining the corresponding virtual equipment according to the first virtual transmission equipment through forwarding hardware.

The first virtual transmission device is a virtual device, such as a virtual network card, for performing data transmission between the virtual device and the forwarding hardware. The virtual transmission device and the virtual device have a one-to-one correspondence relationship, for example, a one-to-one correspondence relationship exists between the virtual network card and the virtual machine. The corresponding relationship is generated when the virtual device is created in the computing device, and after the virtual device is generated, a virtual forwarding device identifier (such as a virtual network card ID) is assigned to each virtual device. At this time, the virtual forwarding device is not established yet.

The virtual transmission identifier is information capable of uniquely determining a virtual transmission device, such as a virtual network card ID.

The first virtual transmission device is created based on the transmission device, which means that the virtual transmission device may be created based on the hardware resource division of the transmission device (e.g., the smart network card).

When the forwarding hardware is provided in the transmitting device, the first virtual transmitting device may also be created based on the forwarding hardware in the transmitting device. When the forwarding hardware is set alone, that is, not set in the transmission device, the first virtual transmission device created by the hardware may also be forwarded.

For example, as described above, the virtual network card is established by an intelligent network card (on the premise that the transmission device is an intelligent network card, the intelligent network card is taken as an example here for description) or an FPGA. The number of the virtual network cards existing in the corresponding relationship is determined by the intelligent network card or the FPGA, for example, 10 virtual network cards are determined, 10 equivalent partitions can be performed according to own hardware resources, such as CPU resources and memory resources, or logic units, storage units, and the like, and the intelligent network card or the FPGA of each hardware resource is used as the virtual network card.

After determining the matching forwarding path, the FPGA may determine a hardware virtual network card according to the virtual network card ID recorded in the forwarding path, and send the video file to the determined virtual machine in an interrupt transmission manner through the virtual IO device.

The virtual IO (Input, Output Input and Output) device refers to a virtual device that can implement IO operation, such as a virtoi device. The virtual IO device is directly established on a hardware device, such as forwarding hardware, through a program, so that the virtual IO device can be regarded as a hardware virtual IO device.

In order to reduce the occupation of the computing resources of the computing device, data transmission may also be performed in a DMA (Direct Memory Access) manner.

At this time, the forwarding hardware may be set in the transmission device, and the transmission device is an intelligent network card having a DMA controller. The intelligent network card also has a processor, and a CPU of the processor can contain a plurality of DMA controllers. The DMA controller will include an address bus, a data bus and control registers. The DMA controller has the ability to access the resources it needs without the intervention of the processor CPU itself, which can generate interrupts.

When data are sent in a DMA mode, the virtual network card stores the video file into the buffer area through the virtIO device, and stores the video file in the buffer area into a storage address in the virtual machine through the DMA controller on the intelligent network card.

It should be noted that when the forwarding hardware is sufficiently advanced, it may have a DMA controller to independently implement DMA-mode data transmission.

Under the condition that at least one virtual device sends data to external equipment, sending the data to be transmitted according to a forwarding path through forwarding hardware, wherein the method comprises the following steps: determining corresponding external equipment according to the forwarding path through forwarding hardware; and transmitting the data to be transmitted to the external equipment through the forwarding hardware.

Since the foregoing has already described the case where the virtual device sends data to the external device, no further description is given here.

In addition, in the case that at least one virtual device transmits data to an external device, the method 200 further includes: and sending the data to be transmitted from the at least one virtual device to forwarding hardware through a first virtual transmission device, wherein the first virtual transmission device is created based on the transmission device.

It should be noted that, when the virtual device sends data to the external device, the virtual device first sends the data to be transmitted to the forwarding hardware through the corresponding first virtual transmission device, and then the data is sent by the forwarding hardware. Since the process is similar to the case where the external device sends the data to the virtual device, or is the reverse process, it is not described here again.

Based on this, the computing device can realize the forwarding of the data through the forwarding hardware, and the forwarding does not occupy the computing resource of the computing device, and the forwarding hardware realizes the forwarding, thereby saving the computing resource of the computing device. Meanwhile, because the computing equipment needs to forward a large amount of data, most of the data forwarding can be shared by the forwarding hardware, so that the data forwarding amount of the computing equipment is reduced, and the forwarding performance of the computing equipment is improved. In order to better implement the embodiment, a better way is to set forwarding hardware, such as an FPGA, in a network card, where the network card may be a common network card or an intelligent network card.

However, since the forwarding hardware is affected by its hardware resources, the forwarding of all data cannot be achieved. In order to solve the problem that a small part of data cannot be forwarded by forwarding hardware, and implement forwarding of the small part, the embodiment of the present application further has the following scheme:

the computing device further includes: the first processing unit is provided with a first virtual forwarding device in operation; wherein, the method 200 further comprises: matching data to be transmitted with at least one forwarding path in forwarding hardware; and under the unmatched result, the data to be transmitted are sent to the first virtual forwarding equipment through the forwarding hardware for data forwarding.

The first processing unit refers to a processor, such as a CPU, on the computing device. A first virtual forwarding device may be running on the processor.

The first virtual forwarding device refers to a virtual network transmission device, and is configured to forward corresponding data received on a physical transmission device (i.e., the transmission device) to a virtual device in the computing device. Such as a Virtual Switch (VS). The virtual forwarding device running on the CPU processor of the computing device may be created on the computing device by a virtual technology, which is described herein since the virtual technology belongs to the prior art.

It should be noted that, for the data forwarding in this case, the computing device may have a common physical network card Nic.

For a common physical network card, especially when the common physical network card is used as a transmission device, the forwarding hardware may be arranged in the common physical network card. Alternatively, the transmission device may include a common physical network card and forwarding hardware, as a network device of the computing device, such as an integrated network card. In this case, for a common physical network card, the forwarding hardware may be an ASIC. For this case, the first virtual forwarding device is disposed on a CPU on the computing device (also referred to as Host), i.e., it runs on the CPU, such as on a CPU of a cloud server. Then the forwarding structure can be as shown in figure 3. For example, as described above, when forwarding hardware, such as an ASIC, receives a video file and determines that the video file does not match a forwarding path in a flow table in the ASIC, the ASIC is required to send the video file to a first layer virtual switch (Host VS) of Host through Nic, that is, a first virtual forwarding device, which may also be referred to as a VS fastpath. The method runs on a CPU of the Host and belongs to software equipment. Forwarding of the video file is performed by VS fastpath.

Specifically, the data to be transmitted is sent to the first virtual forwarding device through the forwarding hardware, and the data forwarding is performed, including: receiving data to be transmitted through first virtual forwarding equipment, and matching the data to be transmitted with at least one forwarding path in the first virtual forwarding equipment; determining a matched forwarding path under the successful matching result; and sending the data to be transmitted according to the forwarding path through the first virtual forwarding equipment.

It should be noted that, since the VS fastpath belongs to a software device, it can handle data forwarding that the forwarding hardware cannot handle. The software device, however, requires the consumption of computing resources, particularly of computing devices, which is much less than the consumption of computing resources for forwarding data by pure software. A flow table is also stored in the VS fastpath, and a plurality of forwarding paths and the like are also recorded in the flow table.

For example, according to the foregoing, after receiving a video file, the VS fastpath parses a message of the video file, obtains a matching field of the message, matches the matching field with a forwarding path in the VS fastpath, determines the matching forwarding path, and may forward the video file according to a pointed virtual device in the forwarding path.

It should be noted that the process of matching forwarding paths and forwarding in VS fastpath is similar to the process of matching forwarding paths and forwarding in forwarding hardware, so detailed descriptions are not provided here, and please refer to the foregoing specific implementation process.

When the external device sends data to the at least one virtual device, sending the data to be transmitted according to the forwarding path may include: determining a second virtual transmission device according to the virtual transmission identifier in the forwarding path through the first virtual forwarding device, wherein the second virtual transmission device runs on the first processing unit; and determining the corresponding virtual equipment according to the second virtual transmission equipment through the first virtual forwarding equipment, and sending the data to be transmitted to the corresponding virtual equipment.

And the second virtual transmission equipment is similar to or the same as the first virtual transmission equipment. The second transmission device is a virtual device, such as a virtual network card, for performing data transmission between the virtual device and the first virtual forwarding device. The virtual transmission device and the virtual device have a one-to-one correspondence relationship, for example, a one-to-one correspondence relationship exists between the virtual network card and the virtual machine. The correspondence is generated when a virtual device is created in the computing device, and after the virtual device is generated, a virtual forwarding device identifier (such as a virtual network card ID or an address) is assigned to each virtual device. The second virtual transmission device can be created on the Host through a virtual technology, and the Host CPU runs the second virtual transmission device, namely the second virtual transmission device belongs to software virtual transmission devices. In addition, the second virtual transmission device may also be created on the forwarding hardware according to the hardware resource of the forwarding hardware, and at this time, the second virtual transmission device is the same as the first virtual transmission device.

For example, according to the foregoing, when the VS fastpath determines the matching forwarding path, the virtual network card may be determined according to the virtual network card ID or the virtual network card address recorded in the forwarding path, and the determined virtual network card may send the video file to the determined virtual machine in an interrupt transmission manner or a DMA manner through the virtual IO device.

It should be noted that, when the virtual network card is set on the forwarding hardware, at this time, the VS fastpath needs to send the video file to the virtual network card corresponding to the forwarding hardware, and the virtual network card sends the video file to the corresponding virtual machine in the computing device. And when the virtual network card is arranged on the computing equipment, the virtual network card can be directly sent to the software virtual network card by VS fastpath on the software. The video file is sent by the hardware virtual transmission equipment, so that the computing resource of the computing equipment can be saved.

In addition, when the virtual device sends data to be transmitted to the external device, the process is similar, and details are not shown here.

However, for the software VS fastpath, there may be data that cannot be processed, so the method 200 may further include: and under the unsuccessful matching result, transmitting the data to be transmitted to third virtual forwarding equipment running on the first processing unit through the first virtual forwarding equipment for data forwarding.

The third virtual forwarding device refers to a virtual network transmission device, and is configured to forward corresponding data received on a physical transmission device (that is, the transmission device) to a virtual device in the computing device. Such as a Virtual Switch (VS). The virtual forwarding device running on the CPU processor of the computing device may be created on the computing device by a virtual technology, which is described herein since the virtual technology belongs to the prior art. The third virtual forwarding device is similar to the first virtual forwarding device. But the third virtual forwarding device is more powerful than the first virtual forwarding device. The third virtual forwarding device may store a plurality of flow tables, each of which records a plurality of forwarding paths. The data to be transmitted may be diverted from one flow table to the next until finally forwarded out. At this time, as shown in fig. 3, if the forwarding structure cannot process the data to be transmitted at VS fastpath, the data to be transmitted is uploaded to a second virtual forwarding device, which may also be referred to as a second layer virtual forwarding device, that is, a VS slowpath (virtual machine slowpath), and the VS slowpath processes and forwards the data to be transmitted.

For example, according to the foregoing, after the VS fastpath cannot determine the matching forwarding path, the video file is sent to the VS slowpath. And after receiving the video file, the VS slowpath sends the video file out.

Specifically, the VS slowpath determines a forwarding path, and forwards the data to be transmitted according to the forwarding path.

For example, according to the foregoing, the VS slowpath parses a packet of the video file, obtains the matching field, determines a final forwarding path according to the multiple flow tables, and forwards the video file according to the forwarding path.

It should be noted that the forwarding process of the VS slowpath is similar to the forwarding process of the VS fastpath, and is not described here again. The final forwarding path may be a set of multiple matched paths.

In addition, if the VS slowpath does not find the forwarding path of the video file, packet loss or other processing may be directly performed.

In order to improve the forwarding hardware and the data forwarding capability of the first virtual forwarding device. The method 200 may further include: matching the data to be transmitted with at least one forwarding path in the third virtual forwarding device, and determining the matched forwarding path; generating at least one forwarding path to be updated according to at least one forwarding path determined for at least one data to be transmitted; and sending at least one forwarding path to be updated to the first virtual forwarding device and the forwarding hardware.

For example, according to the foregoing, after the VS slowpath forwards multiple pieces of data to be transmitted, multiple forwarding paths may be obtained, where each forwarding path may be obtained by multiple matching forwarding paths to which corresponding one piece of data to be transmitted is matched. The VS slowpath takes the obtained multiple forwarding paths as forwarding paths to be updated, and issues the forwarding paths to the forwarding hardware ASIC and the VS fastpath to update the forwarding paths of the ASIC and the VS fastpath, and enriches respective flow tables of the forwarding paths, so that more data to be transmitted can be processed and forwarded, and unnecessary occupation of computing resources is reduced.

Since the forwarding hardware is affected by hardware resources and cannot process all data, not all forwarding paths can be executed, and therefore the third virtual forwarding device needs to send the forwarding paths that can be executed to the forwarding hardware.

Therefore, the method 200 may further include: generating at least one forwarding path to be updated which meets the processing requirement of forwarding hardware according to at least one forwarding path determined aiming at least one data to be transmitted; and sending at least one forwarding path to be updated which can be processed to the forwarding hardware.

For example, according to the foregoing, the VS slowpath may generate a forwarding path to be updated and directly send the forwarding path to the VS fastpath. When the forwarding hardware is targeted, the VS slowpath needs to determine which forwarding paths cannot be executed by the forwarding hardware according to hardware resources of the forwarding hardware, so that the paths that cannot be executed can be deleted from the generated forwarding paths to be updated, and the deleted forwarding paths to be updated are sent to the forwarding hardware. Or the VS slowpath directly generates a plurality of forwarding paths executable by the forwarding hardware for the forwarding hardware, and issues the forwarding paths to the forwarding hardware.

When the third virtual forwarding hardware issues the final forwarding path to be updated to the forwarding hardware, in order to implement the issuing more conveniently and quickly, the path issuing may be performed in the following manner:

sending at least one forwarding path to be updated to forwarding hardware, including: sending the forwarding path to be updated to the first conversion equipment through the third virtual forwarding equipment; and converting the forwarding path to be updated into a forwarding path recognizable by the forwarding hardware according to the type of the forwarding hardware through the first conversion equipment, and sending the forwarding path to the forwarding hardware.

The first conversion device is used for converting the forwarding path to be updated into a forwarding path recognizable by forwarding hardware according to the type of the forwarding hardware and issuing the forwarding path. The first translation device is a software device running on the computing device CPU, which may also be referred to as an xflow abstraction layer. As shown in fig. 5, this xflow may be provided on a network architecture platform, netframe, which is also a software device running on the CPU of the computing device. And interfacing with a third virtual forwarding device.

For example, according to the foregoing, the VS slowpath issues the forwarding path to be updated to the xflow abstraction layer through the preset transmission protocol, and after receiving the forwarding path to be updated, the xflow abstraction layer converts the forwarding path to be updated into the forwarding path that can be identified by the corresponding type of forwarding hardware based on the conversion logic corresponding to the type of forwarding hardware according to the type of forwarding hardware, such as FPGA or ASIC, and different types of forwarding hardware. After the conversion, the xflow abstraction layer transmits the converted forwarding path to be updated to the forwarding hardware, so that the corresponding forwarding hardware can identify the forwarding path to be updated and update the forwarding path.

It should be noted that the conversion logic of different types of forwarding hardware is provided by the manufacturer of its production or development as the usage instruction of the forwarding hardware. In addition, the xflow abstraction layer can be continuously updated according to the type of the forwarding hardware, and the conversion function of new forwarding hardware is added.

Therefore, software logic implementation and a hardware platform can be decoupled, the difference between forwarding hardware types is shielded by software VS by means of the platform capability of xflow in netframe, and forwarding path management related operations related to the forwarding hardware are shielded by an xflow abstraction layer.

Since each forwarding path has its own aging time, i.e., no data passes through the forwarding path for a certain time, the forwarding path needs to be deleted to make more room to store more other forwarding paths. But the aging time may vary from forwarding path to forwarding path. For software managed forwarding paths, these paths may be better managed. However, due to the limited hardware resources of the forwarding hardware and the long development period of the forwarding hardware, it is not suitable to implement complex or frequently-changed logic in hardware, and it is not possible to flexibly manage forwarding paths with different aging times as in software. However, the types of services carried by the VS are very diverse, so it is better to tell the hardware a simple instruction by which the hardware decides what processing action to do for what traffic (or data). In contrast, the forwarding hardware may manage forwarding paths with the same aging time, that is, forwarding paths in the forwarding hardware belong to the same aging time, and may have different starting times but the existing times are the same.

Thus, to better adapt the forwarding hardware, the method 200 further comprises: acquiring the current network connection state from the data to be transmitted through forwarding hardware; and sending the data to be transmitted which can not be processed by the forwarding hardware to the first virtual forwarding equipment according to the network connection state, and sending the data.

The network connection state refers to a network connection condition, and may be divided into a network initial connection state, a network stable connection state, and a network end connection state. Because of the most common of the network stable connected state, the forwarding hardware needs to be maintained in the network stable connected state, i.e. the aging time of its respective forwarding path is corresponding to the network stable connected state. The forwarding paths in the initial network connection state and the end network connection state also have corresponding aging time, and the aging time is different in different states.

For example, according to the foregoing, the ASIC receives a packet, analyzes the packet, obtains some information of the packet, and obtains the network state identifier carried in the packet, thereby determining that the packet is an initial network connection packet. For example, the sync bit SYN in the header of the message should be set to 1, and a sequence number x is selected, indicating that the sequence number of the first data byte when data is transmitted later is x. The message is regarded as a TCP (Transmission Control Protocol) connection request message. At this time, after the ASIC determines the packet, the ASIC uploads the packet to the software VS, such as VS fastpath, regardless of whether the packet matches with a forwarding path therein, and processes the packet. Similarly, for the end bit FIN of the header in the packet is set to 1, the sequence number u is equal to the sequence number of the last byte of the transmitted data plus 1. The ASIC determines that the message is a request network connection termination message, and uploads the message to the software VS, such as VS fastpath, where it processes the message.

In order to flexibly handle the aging times of different forwarding paths, the method 200 further comprises: after the data to be transmitted is sent through the first virtual forwarding device, according to the network connection state, deleting a corresponding forwarding path existing in forwarding hardware through the first virtual forwarding device, wherein the corresponding forwarding path belongs to the forwarding path of the data to be transmitted.

For example, as described above, after the VS fastpath finishes processing the packet, if the packet indicates that the network is in the end connection state, the VS fastpath further needs to delete the corresponding forwarding path in the ASIC, and the deletion may be performed by sending a deletion message. If the ASIC does not have a corresponding path, then it is not deleted.

It should be noted that, no matter the message indicates the initial connection state of the network or the message indicates the end connection state of the network, the VS fastpath may notify the ASIC to delete the corresponding forwarding path. However, since the aging time of the forwarding path corresponding to the network connection ending state is shorter than the aging time of the forwarding path corresponding to the network stable connection state, the corresponding forwarding path in the forwarding hardware needs to be actively deleted, so that the forwarding path does not occupy the storage space of the forwarding hardware too long, and a space is left for other forwarding paths. If the aging time of the forwarding path corresponding to the initial network connection state is longer than that of the forwarding path corresponding to the stable network connection state, the forwarding path may not be deleted because the storage space of the forwarding hardware is not occupied too long.

When the first virtual forwarding device cannot process the reported packet indicating the network status, the method 200 may further include: if the first virtual forwarding equipment does not have a forwarding path of the data to be transmitted, the data to be transmitted is sent to third virtual forwarding equipment; after the data to be transmitted is sent through the third virtual forwarding device, according to the network connection state, deleting a corresponding forwarding path existing in the forwarding hardware through the third virtual forwarding device, wherein the corresponding forwarding path belongs to the forwarding path of the data to be transmitted.

For example, according to the foregoing, if the VS fastpath cannot process the packet, the packet is uploaded to the VS slowpath, and the VS slowpath processes the packet. After the processing, if the packet indicates that the network is in the end connection state, the VS slowpath also needs to delete the corresponding forwarding path in the ASIC, and the deletion can be performed by sending a deletion message. If the ASIC does not have a corresponding path, then it is not deleted. The specific process is similar to the VS fastpath processing process, and is not described herein again.

In addition, when the VS slowpath issues the forwarding path to the forwarding hardware, only the forwarding path corresponding to the network stable connection state is issued, and the forwarding path is issued in the network stable connection state. And the forwarding hardware processes the message corresponding to the network stable connection state, so that data forwarding is realized according to the foregoing.

It should be noted that similar problems exist, many service types need to be abstracted and modified for forwarding hardware, and each service type is not simply converted, and must be sufficiently universal or otherwise meaningless.

In addition, the software creates the forwarding path directly on the forwarding CPU (e.g., the forwarding CPU of the computing device), but the forwarding path needs to be issued to the forwarding hardware. The CPUs are required to issue, and if each CPU issues independently, locking is required, which is poor performance. To solve this problem, the following method can be used:

specifically, sending at least one forwarding path to be updated to forwarding hardware includes: sending at least one forwarding path to be updated to a queue through at least one first processing unit; and sending at least one forwarding path to be updated in the queue to forwarding hardware through a first processing unit.

For example, as shown in fig. 6, according to the foregoing, when the VS slowpath issues the forwarding path to be updated to the ASIC, the multiple data plane CPUs of the computing device store the forwarding path in the queue ring. There may be multiple queues ring. A control surface CPU of the computing device polls the queue ring, and once a forwarding path exists in the queue ring in the polling mode, the forwarding path is issued to the ASIC.

It should be noted that, when the CPU issues the forwarding path, the converted forwarding path may also be issued to the forwarding hardware along the xflow abstraction layer through the xflow abstraction layer. Meanwhile, time overhead and resource overhead brought by locking can be reduced.

In order to save more computing resources of the computing device and forward data that cannot be processed by forwarding hardware, the embodiment of the present application further adopts the following scheme to implement:

specifically, the transmission device further includes: the independent second processing unit runs with a second virtual forwarding device; wherein, the method 200 further comprises: matching data to be transmitted with at least one forwarding path in forwarding hardware; and under the unmatched result, the data to be transmitted are sent to the second virtual forwarding equipment through the forwarding hardware for data forwarding.

The transmission device may further include a hardware device having an independent processing unit (i.e., a second processing unit), such as a hardware device having an independent CPU, and the hardware device may further have an independent kernel, an independent Memory, a DMA (Direct Memory Access) controller, and the like, and may be regarded as a small independent smart terminal. The method and the device can be used for receiving the data to be transmitted sent by the external equipment or sending the data to be transmitted sent by the virtual equipment to the external equipment. The hardware device may be an intelligent network card, and the intelligent network card may be a System-on-a-Chip (SoC) with a CPU. The transmission device can also be an intelligent FPGA chip with the configuration.

The second processing unit refers to a processor, such as a CPU, on the transmission device. A second virtual forwarding device may be running on the processor.

The second virtual forwarding device refers to a virtual network transmission device, and is configured to forward corresponding data received on the physical transmission device (i.e., the above-mentioned intelligent network card) to a virtual device in the computing device. Such as a Virtual Switch (VS). The virtual forwarding device running on the CPU processor of the intelligent network card may be created on the computing device by a virtual technology, which is described herein since the virtual technology belongs to the prior art.

For the intelligent network card, especially when the transmission device further includes an intelligent network card, the forwarding hardware may be an FPGA. Alternatively, the transmission device may be an intelligent network card, and the forwarding hardware may be disposed in the network card. For the above case, the first virtual forwarding device is set on the CPU of the smart network card, that is, it runs on the CPU. Then the flow may be as shown in figure 4 for this forwarding. For example, as described above, the transmission device includes forwarding hardware and an intelligent network card. When forwarding hardware, such as an FPGA receives a video file through a serial interface SERDES (SERializer/DESerializer), and determines that the video file is not matched with a forwarding path in a flow table in the FPGA, the FPGA is required to return the video file to the SERDES, and the SERDES sends the video file to a first layer virtual switch (Moc VS) on an intelligent network card, that is, a second virtual forwarding device, which may also be referred to as a VS fastpath. The intelligent network card runs on a CPU of the intelligent network card and belongs to software equipment. Forwarding of the video file is performed by VS fastpath. And the second virtual forwarding device receives the video file through the ixgbe program driver.

It should be noted that, since the transmission device includes the intelligent network card with an independent computing unit, which is independent of the computing device, the data to be transmitted is transmitted through the transmission device, so that excessive computing resources of the cloud server, such as CPU resources, are not occupied, that is, computing resources shared by the virtual devices in the cloud server are not occupied, and thus the computing resources shared by the virtual devices are effectively improved.

Wherein, will wait to transmit data transmission to the virtual forwarding device of second through the forwarding hardware, carry out data forwarding, include: receiving data to be transmitted through second virtual forwarding equipment, and matching the data to be transmitted with at least one forwarding path in the second virtual forwarding equipment; determining a matched forwarding path under the successful matching result; and sending the data to be transmitted according to the forwarding path through the second virtual forwarding equipment.

It should be noted that, here, the process of performing path matching and forwarding by the second virtual forwarding device is similar to the process of performing path matching and forwarding by the first virtual forwarding device, and details are not repeated here. It should be understood that here the second virtual forwarding device is performed on the smart card, in particular on the CPU of the smart card.

Under the condition that the external equipment sends data to at least one virtual device, sending the data to be transmitted according to the forwarding path, wherein the sending process comprises the following steps: determining a first virtual transmission device according to a virtual transmission identifier in a forwarding path through a second virtual forwarding device, wherein the first virtual transmission device is created based on the transmission device; and determining the corresponding virtual equipment according to the first virtual transmission equipment through the second virtual forwarding equipment, and sending the data to be transmitted to the corresponding virtual equipment.

For example, as shown in fig. 4, according to the foregoing, the VS fastpath sends the video file to the virtual network card through the iohub interface according to the determined forwarding path. Since the second virtual forwarding device sends data to the virtual device according to the first virtual transmission device, which is similar to the process of the first virtual forwarding device sending data to the virtual device according to the first virtual transmission device, the description is omitted here, and only different places are described.

It should be understood that the first virtual transmission device may be created based on hardware resources of forwarding hardware, and may also be created based on hardware resources of the smart network card.

In the event of an unsuccessful match, the method 200 may further include: and sending the data to be transmitted to fourth virtual forwarding equipment running on the second processing unit through the second virtual forwarding equipment for data forwarding.

The fourth virtual forwarding device refers to a virtual network transmission device, and is configured to forward corresponding data received on a physical transmission device (i.e., an intelligent network card) to a virtual device in the computing device. Such as a Virtual Switch (VS). The virtual forwarding device running on the CPU processor of the intelligent network card may be created on the computing device by a virtual technology, which is described herein since the virtual technology belongs to the prior art. The fourth virtual forwarding device is similar to the second virtual forwarding device. But the fourth virtual forwarding device is more powerful than the second virtual forwarding device. The fourth virtual forwarding device may store a plurality of flow tables, each of which records a plurality of forwarding paths. The data to be transmitted may be diverted from one flow table to the next until finally forwarded out. At this time, as shown in fig. 4, when the VS fastpath cannot process the data to be transmitted, the data to be transmitted is uploaded to a fourth virtual forwarding device, which may also be referred to as a second layer virtual forwarding device, that is, a VS slowpath (virtual machine slowpath), and the VS slowpath processes and forwards the data to be transmitted. The forwarding process of the fourth virtual forwarding device is the same as the forwarding process of the third virtual forwarding device, and is not described here again. Only to illustrate, the fourth virtual forwarding device sends the video file to the virtual network card through the iohub interface, and the virtual network card sends the video file to the corresponding virtual machine.

Likewise, to improve the processing power of the forwarding hardware, the method 200 may further include: matching the data to be transmitted with at least one forwarding path in the fourth virtual forwarding device, and determining the matched forwarding path; generating at least one forwarding path to be updated according to at least one forwarding path determined for at least one data to be transmitted; and sending at least one forwarding path to be updated to the second virtual forwarding device and the forwarding hardware.

It should be noted that a process of generating a forwarding path by the fourth virtual forwarding device is similar to a process of generating a forwarding path by the third virtual forwarding device, and is not described herein again. The process of the fourth virtual forwarding device issuing the forwarding path is similar to the process of the third virtual forwarding device issuing the forwarding path, and is not described here again. It is only illustrated that the issuing process in this example is that the fourth virtual forwarding device in the intelligent network card issues to the second virtual forwarding device, and the fourth virtual forwarding device in the intelligent network card issues to the forwarding hardware.

Since the forwarding hardware is affected by hardware resources and cannot execute all forwarding paths, in order to prevent invalid forwarding paths from occupying too much space of the forwarding hardware and reducing the occurrence of such a situation that forwarding cannot be performed, the method 200 may further include: generating at least one forwarding path to be updated which meets the processing requirement of forwarding hardware according to at least one forwarding path determined aiming at least one data to be transmitted; and sending at least one forwarding path to be updated which can be processed to the forwarding hardware.

Since the process of generating at least one forwarding path to be updated that satisfies the requirement that the forwarding hardware can handle and the process of issuing the path have been described in detail in the foregoing, details are not described here.

Sending at least one forwarding path to be updated to forwarding hardware, including: sending the forwarding path to be updated to the second conversion equipment through the fourth virtual forwarding equipment; and converting the forwarding path to be updated into a forwarding path recognizable by the forwarding hardware according to the type of the forwarding hardware through the second conversion equipment, and sending the forwarding path to the forwarding hardware.

The second conversion device is used for converting the forwarding path to be updated into a forwarding path recognizable by the forwarding hardware according to the type of the forwarding hardware and issuing the forwarding path. The second conversion device is a software device running on the intelligent network card CPU, and may also be referred to as an xflow abstraction layer. As shown in fig. 5, the xflow may be set on a network architecture platform netframe, which is also a software device running on the CPU of the intelligent network card. And interfacing with a fourth virtual forwarding device.

The process of forwarding the forwarding path by the second converting apparatus is similar to the process of forwarding the forwarding path by the first converting apparatus, and is not described here again. The second conversion device may also be continuously updated as the first conversion device. Therefore, software logic implementation and a hardware platform can be decoupled, the difference between forwarding hardware types is shielded by software VS by means of the platform capability of xflow in netframe, and forwarding path management related operations related to the forwarding hardware are shielded by an xflow abstraction layer.

Likewise, to better adapt the forwarding hardware, the method 200 further comprises: acquiring the current network connection state from the data to be transmitted through forwarding hardware; and sending the data to be transmitted which can not be processed by the forwarding hardware to the second virtual forwarding equipment according to the network connection state, and sending the data.

The specific implementation of forwarding data according to the network connection state has been described in detail in the foregoing, and is not described herein again, but only described here, where the forwarding hardware, such as the second virtual forwarding device that is uploaded to the intelligent network card by the FPGA, such as the VS fastpath, is used. And carrying out data forwarding in the intelligent network card by VS fastpath.

Likewise, in order to flexibly deal with the aging times of different forwarding paths, the method 200 further includes: and after the data to be transmitted is sent through the second virtual forwarding equipment, deleting a corresponding forwarding path existing in forwarding hardware through the second virtual forwarding equipment according to the network connection state, wherein the corresponding forwarding path belongs to the forwarding path of the data to be transmitted.

The specific process of deleting the forwarding path is described above, and will be described herein again. For illustration only, the forwarding path of the forwarding hardware is deleted by the second virtual forwarding device here. The deletion may be sent by the second virtual forwarding device to the forwarding hardware by a delete message or instruction. So that the forwarding hardware makes more room to store other forwarding paths.

When the second virtual forwarding device is not capable of processing data uploaded by the forwarding hardware due to the network connection status, the method 200 may further include: if the second virtual forwarding equipment does not have a forwarding path of the data to be transmitted, the data to be transmitted is sent to fourth virtual forwarding equipment; and after the data to be transmitted is sent through the fourth virtual forwarding equipment, deleting a corresponding forwarding path existing in forwarding hardware through the fourth virtual forwarding equipment according to the network connection state, wherein the corresponding forwarding path belongs to the forwarding path of the data to be transmitted.

The specific process of deleting the forwarding path is described above, and will be described herein again. For illustration only, the forwarding path of the forwarding hardware is deleted by the fourth virtual forwarding device here. A delete message or instruction may be sent by the fourth virtual forwarding device to the forwarding hardware for deletion. So that the forwarding hardware makes more room to store other forwarding paths.

In order to reduce resource consumption when the software VS on the smart network card sends a forwarding path to the forwarding hardware, the following method may be implemented:

specifically, sending at least one forwarding path to be updated to forwarding hardware includes: sending at least one forwarding path to be updated to a queue through at least one second processing unit; and sending at least one forwarding path to be updated in the queue to forwarding hardware through a second processing unit.

For example, as shown in fig. 6, according to the foregoing, when the VS slowpath in the smart network card issues the forwarding path to be updated to the FPGA, the multiple data plane CPUs of the smart network card store the forwarding path in the queue ring. There may be multiple queues ring. A control surface CPU of the intelligent network card polls the queue ring, and once a forwarding path exists in the queue ring after polling, the forwarding path is issued to the FPGA.

It should be noted that there may be multiple CPUs in the intelligent network card, and when the CPU issues the forwarding path, the converted forwarding path may also be issued to the forwarding hardware along the xflow abstraction layer through the xflow abstraction layer. Meanwhile, time overhead and resource overhead brought by locking can be reduced.

Based on this, the intelligent network card bears the forwarding task of the software VS, and at the same time, the forwarding hardware such as the FPGA is used to forward the data traffic, that is, the transmission device hardware, that is, the intelligent network card and the forwarding hardware, performs data forwarding, and no longer consumes the CPU forwarding resources on the computing device, so that the CPU performance of the computing device is greatly improved. Meanwhile, the forwarding performance can be improved by multiple times through forwarding hardware and software VS (such as VS arranged on an intelligent network card or VS arranged on a computing device), and the delay is greatly reduced. As shown in fig. 7, in the network performance comparison, rectangles in each virtual box sequentially represent VS pure software forwarding (i.e. only set on the CPU of the computing device), and the AWS (amazon cloud service, 2 × 25g network scenario) compares performance of forwarding hardware and software VS acceleration in this embodiment, which shows that this embodiment of the present application is greatly better than other forwarding manners in terms of performance.

The embodiment of the application improves the forwarding performance of the virtual switch through forwarding hardware and improves the flexibility of the virtual switch.

Based on the same inventive concept, fig. 8 is a flowchart illustrating a method for transmitting data according to another exemplary embodiment of the present application. The method 800 provided by the embodiment of the present application is performed by a transmission device having forwarding hardware, such as an intelligent network card. The method 800 includes the steps of:

Further, the transmission device further includes: the system comprises an independent processing unit, a first virtual forwarding device and a second virtual forwarding device, wherein the first virtual forwarding device runs on the processing unit; wherein the method 800 further comprises: matching data to be transmitted with at least one forwarding path in forwarding hardware; and under the unmatched result, the data to be transmitted are sent to the first virtual forwarding equipment through the forwarding hardware for data forwarding.

Wherein, through transmitting hardware and will wait to transmit data transmission to first virtual forwarding device, carry out data forwarding, include: receiving data to be transmitted through first virtual forwarding equipment, and matching the data to be transmitted with at least one forwarding path in the first virtual forwarding equipment; determining a matched forwarding path under the successful matching result; and sending the data to be transmitted according to the forwarding path through the first virtual forwarding equipment.

Under the condition that the external device sends data to the at least one virtual device, sending the data to be transmitted according to the forwarding path, wherein the sending method comprises the following steps: determining virtual transmission equipment according to a virtual transmission identifier in a forwarding path through first virtual forwarding equipment, wherein the virtual transmission equipment is created based on the transmission equipment; and determining the corresponding virtual equipment according to the virtual transmission equipment through the first virtual forwarding equipment, and sending the data to be transmitted to the corresponding virtual equipment.

In addition, the method 800 further includes: and under the unsuccessful matching result, transmitting the data to be transmitted to second virtual forwarding equipment running on the processing unit through the first virtual forwarding equipment for data forwarding.

In addition, the method 800 further includes: matching the data to be transmitted with at least one forwarding path in the second virtual forwarding equipment, and determining the matched forwarding path; generating at least one forwarding path to be updated according to at least one forwarding path determined for at least one data to be transmitted; and sending at least one forwarding path to be updated to the first virtual forwarding device and the forwarding hardware.

Sending at least one forwarding path to be updated to forwarding hardware, including: sending the forwarding path to be updated to the conversion equipment through the second virtual forwarding equipment; and converting the forwarding path to be updated into a forwarding path recognizable by the forwarding hardware according to the type of the forwarding hardware through the conversion equipment, and sending the forwarding path to the forwarding hardware.

In addition, the method 800 further includes: acquiring the current network connection state from the data to be transmitted through forwarding hardware; and sending the data to be transmitted which can not be processed by the forwarding hardware to the first virtual forwarding equipment according to the network connection state, and sending the data.
