[0102] The queue module 110 supports the management of hardware queues and software queues, and is responsible for the scheduling of data packet processing of the hardware accelerator module and the CPU; the hardware accelerator module, the CPU and the queue module interact through message descriptor information.
[0103] The network port module can correspond to a variety of different network ports, such as Ethernet interface, USB interface, PCI E interface, etc. Different network ports require corresponding message processing modules. After processing, the Ethernet message is obtained and then queued to the parsing module for subsequent exchange and message processing.
[0104] The hardware accelerator module is a functional module that performs hardware unloading. Different projects require different hardware unloading functions. Different hardware accelerator modules can interact through the queues in the queue module. After each hardware accelerator module completes its message processing function, it will initiate a queue request. The queue module will make a judgment based on the queue request and queue the message identification information into the corresponding queue.
[0105] The switching module can perform layer 2 and layer 3 switching and related processing. According to different message descriptor information, different key values can be used for switching table lookup, and different switching processing can be performed according to the table lookup results.
[0106] The processor interface module supports multiple CPU cores. The hardware accelerator module interacts with the CPU through the queue corresponding to the CPU in the queue module. The CPU queue is uniformly allocated by the software, and the CPU can be directly queued into a software queue or hardware queue.
[0107] Embodiment 2
[0108] This embodiment is based on the message processing device of the first embodiment.

The table entries can statically configure the queue-related information and message processing information that need to be exchanged.
[0112] (3) Initialize the queue decision table entries according to the business flow, that is, the correspondence between the queue and the functional module;
[0113] After initialization, the message can be sent and received. Using the queue to determine the next processing module can achieve a flexible message exchange processing flow. The hardware accelerator module can also be flexibly allocated to different business flows. Different business flows can use or share the hardware accelerator module.

If there is no other business, all forwarding table items can be configured as L2 forwarding table items. After the table lookup is successful, the L2 forwarding table item information is obtained, and then corresponding processing is performed according to the L2 forwarding table item information, such as L2 message header modification, etc., and an enqueue request is initiated according to the message descriptor information and the L2 forwarding table item information.
[0122] (6) The queue module performs a table lookup based on the queue entry request information and determines that the queue to be entered is the queue corresponding to the Ethernet interface module;
[0123] (7) The Ethernet interface module obtains the message according to the message descriptor information and performs corresponding processing on the message, and then sends the message from the network port.

[0131] (6) The queue module looks up the table according to the queue entry request information and determines that the queue to be entered is the queue corresponding to the switching module;
[0132] (7) The queue corresponding to the switching module is dequeued, and the L3 information is used to check the hash table (L2 forwarding table and L3 forwarding table share storage) according to the message descriptor information; after the table check is successful, the L3 forwarding table information is obtained, and corresponding processing is performed according to the L3 forwarding table information, such as NAT modification of the message; an enqueue request is initiated according to the message descriptor information and the L3 forwarding table information
[0133] (8) The queue module performs a table lookup based on the queue entry request information and determines that the queue to be entered is the queue corresponding to the hardware accelerator module required by the CPU;
[0134] (9) The queue corresponding to the hardware accelerator module is dequeued, and the corresponding CPU function processing that needs to be offloaded by hardware is performed to reduce CPU overhead; after the offload function processing is completed, an entry request is initiated
[0135] (10) The queue module performs a table lookup based on the queue entry request information and determines that the queue to be entered is the CPU queue;
