Embodiment Construction

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0049] The present invention provides a method for identifying P2P services, judging whether the data flow belongs to the P2P service flow according to the pre-stored P2P flow behavior characteristics, and when the data flow is a P2P service flow, the message characteristics of the data flow are compared with the pre-stored P2P flow Packet features are matched to determine the specific service type of the P2P service flow, so as to solve the problem that the P2...

Abstract

The embodiment of the invention discloses a method for recognizing P2P services and a device thereof. In the scheme, the method comprises: firstly, judging whether data streams belong to P2P service streams or not according to pre-stored P2P steam behavior characteristics, and effectively recognizing encrypted streams since the external stream characteristics of the data steams are detected, wherein the detection process is rapider, thereby guaranteeing the effectiveness of recognizing the P2P service streams, then, matching message characteristics of the data streams with the message characteristics of the pre-stored P2P streams when the data streams are detected to be P2P service streams, confirming concrete service types of the P2P service streams, and solving the problem in the prior art that simultaneous rapid and accurate detection of the P2P service streams is unavailable.

Description

technical field [0001] The present invention relates to the field of network service identification, more specifically, to a P2P (Point to Point, point-to-point) service identification method and device. Background technique [0002] Currently, P2P computing has occupied an important field of distributed computing. Compared with the traditional centralized server-based service model, the P2P model is a distributed model, which enables each node in the network to share information and cooperate with each other; it allows users to upload information while downloading information, compared to the previous For traditional network services, it has the characteristics of high-speed transmission, large data volume, and symmetrical uplink and downlink traffic. P2P computing has not only aroused widespread concern in the academic circles, but it has also aroused great interest in the computer industry. [0003] With the rapid development of Internet technologies, applications, and ...
