Problems solved by technology

[0004] However, the inventor found in the research that in the existing application identification engine, if the identification method based on the length feature of the business data is modified or upgraded, that is, when the identification method based on the length feature is extended, every time Expansion requires developers to modify the code of the recognition method accordingly, resulting in time-consuming and labor-intensive work for developers and low work efficiency

Embodiment 1

[0026] see figure 1 , which is a method for identifying business data in a peer-to-peer network in the present application, the method includes the following steps:

[0027] Step 101: receiving a feature file, the feature file includes a length feature rule established based on the length feature of business data;

[0028] Wherein, the length feature includes: the number of identified packets, the length feature of the identified packets, and the sequence of the length feature.

[0029] The identified length feature includes: any one or any combination of a preset fixed value, a preset interval value, and preset discrete values.

[0030] For example, the session types in the current P2P technology include: BT, eMule and Vagaa, etc. When identifying the service data whose session type is BT based on the feature of service data length, the corresponding length rule is: in any three consecutive messages in a session connection, if the length of the first message is 56 character...

Embodiment 2

[0043] The method for identifying service data in the peer-to-peer network will be described in detail below by taking a peer-to-peer network structure as an application scenario. see figure 2 , which is a flow chart of another embodiment of a method for identifying service data in a peer-to-peer network of the present application, and the identification method specifically includes the following steps:

[0044] Step 201: The access layer gateway receives the feature file;

[0045] Among them, see image 3 , which is a schematic structural diagram of a peer-to-peer network in the present application, such as image 3 As shown, the P2P network structure is different from the traditional C / S structure and B / S structure. There is no central node or central server in the entire network, and each node in the network has three functions: information consumer, information provider and information communication. aspects of the function. In order to realize the identification of b...

Embodiment 3

[0072] Corresponding to the foregoing method for identifying service data in a peer-to-peer network, an embodiment of the present application further provides an apparatus for identifying service data in a peer-to-peer network. see Figure 5 , which is a structural diagram of an embodiment of an apparatus for identifying service data in a peer-to-peer network in the present application, and the apparatus includes a receiving unit 501 , an extracting unit 502 and an identifying unit 503 . The internal structure and connection relationship of the device will be further introduced below in conjunction with the working principle of the device.

[0073] The receiving unit 501 is configured to receive a feature file, the feature file includes length feature rules established based on service data length features;

[0074] An extraction unit 502, configured to extract length feature rules from the feature file;

[0075] The identification unit 503 is configured to identify...

Abstract

The embodiment of the invention discloses a method and device for identifying business data in peer-to-peer network, wherein the method comprises the following steps: receiving a feature file which comprises a length feature rule established based on the length feature of the business data; extracting the length feature rule from the feature file; and identifying the business data in the conversation according to the extracted length feature rule. According to the embodiment of the invention, the regularization of the length feature identification is realized, and the work efficiency of development personnel can be improved when the identification method of the length feature is expanded.

Description

technical field [0001] The present application relates to the technical field of communication and computer, in particular to a method and device for identifying business data in a peer-to-peer network. Background technique [0002] P2P (Peer to Peer, peer-to-peer network) has been popularized and developed very quickly since its appearance. The P2P network structure is different from the C / S (Client / Server, client / server) structure and B / S (Browser / Server, browser / server) structure. The most notable feature of P2P is that there is no central node or The central server, each node in the network has the functions of information consumer, information provider and information communication at the same time. Therefore, realizing file sharing and downloading in P2P brings great convenience to users. However, with the popularity of P2P, the business data in P2P occupies a large amount of resources of bandwidth access, causing the normal use of other services such as Web, Email, a...
