The method for realizing service awareness includes: extracting flow characteristic data; constructing a collection of flow model instances; sensing the flow model instances, and outputting recognition results. The device for realizing business awareness includes: a fast identification module for quickly identifying flow model instances; a machine learning module for further processing flow model instances that cannot be identified by the fast identification module, and outputting identification results.

Description

technical field [0001] The present invention relates to the field of network technology, in particular to a system, method and equipment for realizing service awareness. Background technique [0002] With the popularity of the Internet, users' demand for communication services continues to increase. People are no longer satisfied with simple Internet applications such as browsing the web, but hope to enjoy higher-speed and richer multimedia applications, such as voice over IP (VoIP , Voice over IP, video telephony, video conferencing, video on demand (VOD, Video on Demand), interactive Internet TV (IPTV) and other applications; on the other hand, mainstream fixed network operators are also facing the depreciation of traditional voice services Therefore, they hope to make full use of network resources, find new business growth points, increase business income, and reduce operating costs. [0003] However, with the emergence of a large number of new network applications in re...

Problems solved by technology

However, there are many deficiencies in the deep packet inspection method: First, this method theoretically needs to analyze the payload (effective data carried in the data packet) of each data packet. If the amount of data is large, it requires a lot of hardware processing power High, the strategy will be quite complicated; secondly, detecting the content of the data packet will also involve the issue of privacy protection; thirdly, once the application program encrypts the data payload, this method will not work; finally, deep packet inspection The method has poor flexibility. If the protocol used by the application changes or a new business type appears, the matching rules need to be changed

This method is not sensitive to protocol changes and can identify encrypted data streams or new data stream types. However, this method can only identify the general type of stream (such as Web, P2P, etc.), and it is difficult to determine which specific application it belongs to. For example, it can be identified as a P2P data stream, but it cannot be identified which protocol it uses, that is, the specific business type. For example, it cannot be distinguished whether it is a BT download or an eDonkey download.
