Problems solved by technology
While these platforms bring convenience to people, they also bring a series of problems: the large-scale use of P2P-based application technology occupies a large amount of network bandwidth; because each uses a different private protocol, it is easy to escape the scope of supervision; and The vulnerability of the network itself, these platforms are easy to become the target of some criminals and reactionary forces, making them a channel for disseminating illegal information, endangering the interests of the country and society

Embodiment 1
[0098] The present embodiment adopts the method for extracting the occurrence rules of the channel signature codes in the technical solution of the present invention to extract the occurrence rules of the channel signature codes of the four platforms of PPLive, PPStream, QQLive and UUSee:
[0099] Among the four platforms, UUSee is the most special. There is a UUTV_UUPlayer.xml file in the installation directory of the UUSee client software, which includes the feature code information of all channels of UUSee, for example:
[0100]
[0101] Change the byte order of the first three segments of the bytecode, that is, convert 004A3C5E-A8EF-424A to 5E3C4A00-EFA8-4A42, and the entire bytecode segment after conversion is the feature code of the channel. In order to analyze the appearance of the channel feature codes, use Wireshark on a PC in the campus network to collect two different channels of UUSee: 1800 seconds of data from Hunan Satellite TV and First Finance and Economics, u...

The invention relates to the field of P2P (Peer 2 Peer) flow rate recognition, in particular discloses a method for extracting the occurrence law of a P2P-TV channel feature code, a P2P-TV channel recognition method and a recognition system based on the extraction method. The recognition method comprises the following steps of: analyzing acquired data to obtain the occurrence frequency of a byte code segment in UDP (User Datagram Protocol) data, and finding out the occurrence frequency of the channel feature code according to the occurrence frequency; obtaining the channel feature code of each platform based on the occurrence law of the channel feature code, matching with a feature code base and analyzing to obtain the channel information of each platform; and realizing the accurate recognition for the channel of each platform. The channel recognition method has fast running speed and precise recognition result, the recognition system has simple structure, and the safety monitoring ofa network to be controlled is effectively realized.
Description
technical field [0001] The present invention relates to the field of P2P traffic identification, and more specifically, to the identification technology of P2P-TV channels corresponding to network traffic. Background technique [0002] As a new network service, P2P-TV is rapidly popular on the Internet. People can easily use the P2P-TV platform to watch TV, movies, etc. Now the popular P2P-TV platforms on the Internet include PPLive, PPStream, QQLive, UUSee, SOPCast, etc. Wait. While these platforms bring convenience to people, they also bring a series of problems: the large-scale use of P2P-based application technology occupies a large amount of network bandwidth; because each uses a different private protocol, it is easy to escape the scope of supervision; and Due to the vulnerability of the network itself, these platforms are easy to become the targets of some lawbreakers and reactionary forces, making them a channel for disseminating illegal information, endangering the...
