A message acceleration method and device for software and hardware coordination

Abstract

The invention discloses a message acceleration method and device with software and hardware cooperation. The message acceleration method includes: the software acceleration layer judges whether the message carries tag information; if the message does not carry the tag information, the protocol stack Forward the message, and obtain the hardware acceleration behavior and software acceleration behavior of the message according to the forwarding result of the protocol stack; the software acceleration layer allocates tag information according to the business type of the message, establishes a business processing module based on the tag information, and accelerates the software The behavior is sent to the business processing module; the software acceleration layer establishes hardware search rules according to the characteristic information of the message, and establishes the first association relationship between the hardware search rules, hardware acceleration behavior and tag information, and sends the first association relationship to the hardware acceleration layer; if the message carries tag information, the message is distributed to the corresponding business processing module according to the tag information of the message, and the service processing module performs software acceleration on the message according to the corresponding software acceleration behavior.

Description

technical field [0001] The invention belongs to the field of communication, and more specifically relates to a message acceleration method and device with software and hardware cooperation. Background technique [0002] With the country's call for network speed-up, the data load of gateway products has increased sharply, followed by the rapid development of hardware accelerators or network processors NP (Network Processor, abbreviated as NP). Usually, the home gateway modifies and forwards messages by learning the Linux network protocol stack, and sends the messages to the hardware accelerator or NP. Subsequent messages will directly bypass the network protocol stack to achieve hardware acceleration. [0003] At present, packet forwarding devices such as home gateways can well support hardware acceleration of L2-L3 layer packets. With the increase and change of protocols, there are more and more business types and application scenarios, such as DsLite tunnel, VxLAN Tunnel, ...

Problems solved by technology

[0004] In view of the above defects or improvement needs of the prior art, the present invention provides a message acceleration method and device with software and hardware synergy, the purpose of which is that the hardware acceleration layer is responsible for the acceleration behavior of the L2-L3 layer, and the software acceleration layer is responsible for the acceleration behavior of the L4-L7 layer. Layer acceleration behavior, the software acceleration layer and the hardware acceleration layer cooperate to accelerate the L2~L7 layers of the message, which greatly improves the message acceleration without increasing the hardware design cost, hardware power consumption and hardware design difficulty. efficiency, so as to solve the problem of using hardware acceleration to accelerate L2-L7 layer services, the hardware acceleration method has high requirements for chip design, and the complexity of the chip is very high. Not only does it require high design costs, but also the chip The technical problem that the power consumption also increases
