Abstract

The invention discloses a method for accelerating data processing and forwarding of a DPI device and a DPI device. The method includes the following steps: uniformly dispersing received traffic to a plurality of traffic identification and classification processing modules; each traffic identification and classification processing module Perform protocol detection according to the received traffic, and update the connection tracking information; filter the traffic processed by the traffic identification and classification processing module according to the preset access control list; process the filtered traffic through speed limit and shaping to retweet. The technical scheme of the invention overcomes various technical defects mentioned in the prior art, and significantly improves the data processing and forwarding speed.

Description

technical field [0001] The present invention relates to the field of network technologies, in particular to a method and DPI device for accelerating data processing and forwarding of DPI devices. Background technique [0002] In recent years, the network has developed more and more rapidly, the scale of the network has continued to expand, the number of network users has continued to increase, the types of applications and services provided by the network have continued to be enriched, and the network has become more and more complex. New network services emerge in an endless stream, including P2P, VoIP, streaming media, Web TV, audio and video chat, interactive online games, and virtual reality. The data traffic of new services is quite huge, which increases network congestion to a large extent, reduces network performance, deteriorates network service quality, and hinders the development of normal network services and the popularization of key applications. [0003] Impro...
