Software and hardware collaborative message acceleration method and device

Abstract

The invention discloses a software and hardware cooperative message acceleration method and device. The message acceleration method comprises the steps that a software acceleration layer judges whether a message carries mark information or not; if the message does not carry the mark information, the message is forwarded through a protocol stack, and a hardware acceleration behavior and a softwareacceleration behavior of the message are acquired according to a forwarding result of the protocol stack; the software acceleration layer allocates mark information according to the service type of the message, establishes a service processing module according to the mark information, and issues a software acceleration behavior to the service processing module; the software acceleration layer establishes a hardware search rule according to the feature information of the message, establishes a first association relationship among the hardware search rule, the hardware acceleration behavior andthe mark information, and issues the first association relationship to the hardware acceleration layer; and if the message carries the mark information, the message is allocated to a corresponding service processing module according to the mark information of the message, and software acceleration is carried out on the message by the service processing module according to a corresponding softwareacceleration 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
