Embodiment 2

[0074] Such as Figure 4 As shown, it is the second embodiment of the present invention, a flow chart of a P2P service access method for DPI analysis to terminate P2P transmission. For the convenience of description, in this embodiment, the access node 6 is called AN1, and AN2 is called AN2 , AN1 and AN2 are collectively referred to as P2P tunnel path nodes.

[0075] Specifically include the following steps:

[0076] P2P tunnel establishment phase:

[0077] Step S401, sender A sends a P2P data packet to AN1.

[0078] In step S402, the DPI proxy module 11 of AN1 recognizes that the packet from sender A is a P2P data packet through flow classification and / or DPI filtering.

[0079] Step S403 , redirecting the P2P data message to the data parsing unit 5 .

[0080] Step S404, the data analysis unit 5 performs DPI analysis on the P2P data or signaling message, identifies the application service type and content of the corresponding flow or analyzes the P2P signaling, and finds ou...

Embodiment 3

[0104] Such as Figure 5 As shown, it is a flowchart of a P2P service access method for signaling to terminate P2P transmission in Embodiment 3 of the present invention. For the convenience of description, in this embodiment, the access node 6 is called AN1, and AN2 is called AN2 , AN1 and AN2 are collectively referred to as P2P tunnel path nodes.

[0105] Specifically include the following steps:

[0106] P2P tunnel establishment phase:

[0107] Step S501, sender A's P2P data message is uploaded to AN1.

[0108] In step S502, the DPI proxy module 11 of AN1 recognizes that the packet from sender A is a P2P data packet through flow classification and / or DPI filtering.

[0109] Step S503 , redirecting the P2P data packet to the data parsing unit 5 .

[0110] Step S504, the data parsing unit 5 parses the P2P signaling message.

[0111] Step S505 , according to the DPI-related policy, send the P2P tunnel and policy configuration command to the control node 2 .

[0112] Step ...

Abstract

The embodiment of the invention discloses a method for P2P service access, which comprises the following steps of: acquiring the initial information of a P2P service and determining a P2P tunnel path; controlling a starting node of a P2P tunnel and an end node of the P2P tunnel to build the P2P tunnel according to the P2P tunnel path, and using the P2P tunnel to carry the P2P service; acquiring termination information of the P2P service; and controlling the starting node of the P2P tunnel and the end node of the P2P tunnel to eliminate the P2P tunnel to terminate the P2P service. The embodiment of the invention also discloses a system and a device for P2P service access. The method, the system and the device realize the control of the P2P service and load separation, and reduce the data flow accessing an aggregation network, hardware cost and data processing load.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a P2P service access method, system and device. Background technique [0002] With the rapid development of the Internet, various broadband services are also growing rapidly, which brings opportunities and challenges to operators, such as bandwidth management, content billing, information security and other new problems. in front of them. Among them, the most prominent performance is the P2P (Point-to-Point, point-to-point) application. P2P technology breaks the C / S (Client-Server, client-server) traffic model, adopts the "no centralized server" mode, eliminates the bottleneck problem of the server, and quickly penetrates into business fields such as file download and streaming media. According to statistics, at present, P2P traffic has accounted for more than 50% of network traffic, and this figure is showing a rising trend, and it is even considered a killer ap...
