Embodiment Construction

[0073] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0074] The present invention mainly analyzes the characteristics of poor performance of the SD-WAN data tunnel using the UDP protocol and provides a solution for performance improvement. Since each manufacturer's SD-WAN function implementation is different, but its kernel data tunnel is forwarded through the protocol stack, so the present invention is described in the form of a kernel module, intending to present the optimization scheme as a whole.

[0075] Sdwan does not accelerate the normal data packet forwarding process. When only considering the WAN side as dynamic / static and PPPOE access mode (not considering VPN dual access), the forwarding of tunnel data packets in the network equipment needs to go through multiple IP protocols. Stack processing, sdwan kernel module processing, PPP driver processing. And based on the quintuple consist...

Abstract

The invention provides a method and a system for realizing sdwan data tunnel forwarding acceleration, and belongs to the technical field of data processing. The method comprises the following steps of: after receiving data, storing the data into a hardware queue; whether a packet receiving control technology is started or not is judged, if yes, multi-core distribution acceleration forwarding processing is conducted on downlink data packets, all CPUs recognize and accelerate sdwan data tunnel messages through independent data packet acceleration forwarding processing modules, if not, the sdwan data tunnel messages are recognized and accelerated through the independent data packet acceleration forwarding processing modules, and the sdwan data tunnel messages are accelerated. The invention further provides a system for realizing the method, and the method has the beneficial effects that the independent kernel module takes over the data packets of the sdwan to carry out packet forwarding, the process is simpler, routing query does not need to be carried out on all the data packets, a large number of legality detection actions are reduced, and the forwarding performance is obviously improved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method for realizing SDWAN data tunnel forwarding acceleration, and also relates to a system for realizing the method for realizing SDWAN data tunnel forwarding acceleration. Background technique [0002] SDWAN (Soft Define WAN translation: Software Defined Wide Area Network) tunneling technology: SDWAN is considered a cost-effective technology for connecting remote sites that require ultra-low reliable connections for low-latency and business-critical applications. SD-WAN requires a method of connectivity between two or more locations. This connection typically includes MPLS, Internet broadband, or both. The goal is to expand the use of low-cost connections while meeting the same latency and throughput requirements. At present, SD-WAN tunneling technologies mainly include TCP / UDP socket-based tunneling (poor performance, high performance requires CPU support), Netmap...
