The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part 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.
Referring to fig. 1, a schematic block diagram of an intelligent network card system provided in an embodiment of the present application is shown, where the system includes a network card module 1, a programmable integrated circuit module 2, and a main processor 3;
the network card module 1 and the programmable integrated circuit module 2 form an intelligent network card, and the intelligent network card is generally applied to network devices such as servers. The main processor 3 is a processor within the network device.
In an embodiment of the present Application, the Network Card module 1 may adopt a Network Card (NIC) chip, where the NIC chip belongs to an Application Specific Integrated Circuit (ASIC) chip, and is an ASIC designed specifically for implementing a Network Card function.
The Programmable integrated circuit module 2 may be a Field Programmable Gate Array (FPGA) chip, and a processor unit is embedded therein.
The main processor 3 is a Host CPU in a network device, wherein the network device may be a server, and the server may be one server device or a server cluster composed of a plurality of server devices.
The network card module 1 and the programmable integrated circuit module 2 are connected through a communication bus, and the programmable integrated circuit module 2 is provided with a network interface for connecting an external network.
The network card module 1 and the programmable integrated circuit module 2 are both connected with the main processor 3 through a communication bus, and an information synchronization channel is established between the programmable integrated circuit module 2 and the main processor 3 and is used for controlling information synchronization.
For example, the NIC chip and the FPGA chip may be connected by an ethernet bus; and the NIC chip and the FPGA chip are connected with the Host CPU of the server through the PCIE bus.
The initialization process of the intelligent network card is described below by taking an NIC chip, an FPGA chip and a Host CPU as examples:
during initialization, configuring both a Host CPU and a CPU embedded in an FPGA chip as a control plane of an intelligent network card; moreover, a user can configure any one of the control planes as a main control plane and the other control plane as a standby control plane according to the requirement of the user; for example, a Host CPU can be configured as a main control plane, and a CPU embedded in an FPGA is configured as a standby control plane; or, configuring a CPU embedded in the FPGA as a main control plane, and configuring a Host CPU as a standby control plane.
And establishing an information synchronization channel between the Host CPU and the CPU embedded in the FPGA for synchronizing control information.
Configuring an NIC chip, an FPGA and a Host CPU as forwarding planes, wherein the NIC chip is a first forwarding plane, the FPGA is a second forwarding plane and the Host CPU is a third forwarding plane;
in addition, the NIC chip has the advantages of large bandwidth and low time delay of the processing message of the ASIC chip, but has the disadvantages of low complexity and limited resources of the processing message; compared with an NIC chip, the FPGA has slightly lower message processing bandwidth and slightly higher time delay, can process more complex messages and has more sufficient resources than the NIC; compared with NIC and FPGA, the Host CPU has the advantages of lowest message processing bandwidth and largest time delay, but can process complex messages and has the most repeated resources.
The user may configure the priorities of the three forwarding planes according to actual requirements, for example, if the user has a relatively high requirement on the delay, the priorities may be, in order from high to low: a first forwarding plane, a second forwarding plane, and a third forwarding plane.
After the initialization configuration process is completed, the two control planes can monitor whether the two control planes and the other control plane are abnormal or not, and if any one control plane is abnormal, the control plane without the abnormality can be started to continue to complete the control flow; and the main control plane monitors whether the currently used forwarding plane is abnormal or not, and if the currently used forwarding plane is abnormal, the forwarding rules are transferred from the current forwarding plane to the forwarding plane with the priority level of the current forwarding plane according to the priority level sequence of the forwarding plane, so that the data can be normally forwarded and processed.

Referring to fig. 2, a flowchart of a control plane switching method according to an embodiment of the present application is shown, where the method is applied to a first control plane and a second control plane, in this embodiment, both the control planes can monitor whether the control plane and another control plane are abnormal, and when it is detected that any one of the control planes is abnormal, the other control plane is switched to implement a control function.
As shown in fig. 2, the method may include the steps of:
s110, detecting whether the current main control plane and the current standby control plane are abnormal or not; if the current standby control plane is detected to be abnormal, executing S120; if it is detected that the current primary control plane is abnormal, S140 is executed.
The main control plane and the standby control plane are configured when the system is initialized, and a user can configure the main control plane and the standby control plane according to the actual requirements of the user.

If the backup control plane detects that the backup control plane has an abnormality, the backup control plane is automatically restarted to eliminate the abnormality.
S130, if the current standby control plane is eliminated, the current main control plane synchronizes the control information to the current standby control plane.
If the current standby control plane is eliminated by restarting the abnormity, the control information of the current main control plane is synchronized to the current standby control plane through an information synchronization channel, so that the current standby control plane realizes the control process when the current main control plane is abnormal.
And S140, controlling the current main control plane to restart, and controlling the current standby control plane to be changed into a new main control plane.
And if the current main control plane is detected to be abnormal, controlling the current standby control plane to be switched to a new main control plane, switching the current main control plane to a new standby control plane, and controlling the current main control plane to be restarted.
In the embodiment of the application, the two actions of controlling the current main control plane to restart and controlling the current standby control plane to be changed into a new main control plane can be executed in parallel or in sequence, for example, the restart can be controlled first, and then the main control plane is switched; or, the main control plane may be switched first, and then the restart is controlled.
In one embodiment of the application, the current main control plane is a Host CPU, and the current standby control plane is an embedded CPU of an FPGA;
if the Host CPU detects that the Host CPU is abnormal, the embedded CPU of the FPGA becomes a main control plane, and meanwhile, the Host CPU is restarted to eliminate the abnormality.
And if the embedded CPU of the FPGA detects that the Host CPU is abnormal, the embedded CPU of the FPGA is controlled to become a main control plane, and the Host CPU is informed to be restarted to eliminate the abnormality.
S150, if the current main control plane eliminates the abnormity, the new main control plane synchronizes the control information to the current control plane.
Still take the case that the current main control plane is the Host CPU and the current standby control plane is the embedded CPU of the FPGA as an example for explanation, and after the Host CPU eliminates the abnormality, the control information in the embedded CPU of the FPGA is synchronized to the Host CPU.
In the control plane switching method provided in this embodiment, both the two control planes can monitor the abnormality of the control plane itself and the other control plane, and if it is monitored that the main control plane is abnormal, the standby control plane is changed into the main control plane, and the control plane with the abnormality is controlled to restart. And if the backup control plane is detected to be abnormal, restarting the backup control plane and synchronizing the control information of the main control plane to the backup control plane so that the backup control plane can enter a main control state at any time. The method realizes redundancy control through two control planes, and improves the reliability of the intelligent network card.

As shown in fig. 3, the method may include the steps of:
s210, when the main control plane detects that the current forwarding plane is abnormal, the forwarding rules are transferred from the current forwarding plane to a target forwarding plane with the next priority of the current forwarding plane according to the sequence of the priorities from high to low.

And S220, when the current forwarding plane is detected to be recovered to normal, migrating the forwarding rule from the target forwarding plane to the current forwarding plane.
And when the main control plane detects that the current forwarding plane is recovered to be normal, the forwarding rule is migrated from the target forwarding plane to the current forwarding plane.
Referring to fig. 4, a flowchart of a forwarding plane switching method provided in an embodiment of the present application is shown, where the embodiment will describe in detail a switching control process between forwarding planes; the method may be applied within a main processor or processor unit as shown in fig. 1.
As shown in fig. 4, the method may include the steps of:

if the abnormal type is software failure, executing S320; if the exception type is resource shortage, executing S340;
