Embodiment 1

[0074] In order to solve the above technical problems, the embodiment of the present invention provides a bidirectional service data flow identification method, such as figure 1 shown, including:

[0075] S1: Perform frame counting on the business data flow, and perform deep packet detection and identification on the same frame data after the frame counting is completed;

[0076] S2: Carry out result arbitration on the identification results of the same frame data, and obtain the deep packet detection identification results of the frame data;

[0077] S3: Detect whether there is frame data with unrecognized results, and perform in-depth flow detection and recognition on the frame data with unrecognized results, and obtain the recognition results of bidirectional business data flow;

[0078] The service data flow includes an uplink service data flow and a downlink service data flow;

[0079] The frame counting of the service data flow further includes:

[0080] The identific...

Embodiment 2

[0112] The embodiment of the present invention also provides a two-way service data flow identification device, including:

[0113] downlink sending device and uplink sending device;

[0114] The downlink sending device is used to send uplink service data flow;

[0115] The uplink sending device is configured to send downlink service data streams;

Abstract

The present invention provides a two-way service data flow identification method and device, the method comprising: performing frame counting on the service data flow, performing deep packet detection and identification on the same frame of data; performing result arbitration on the identification results of the same frame of data; detecting whether There are frame data with unrecognized results, and deep flow detection and identification are performed on the frame data with unrecognized results to obtain the identification results of bidirectional service data flows; the service data flows include uplink service data flows and downlink service data flows; The identification process of the uplink service data flow and the downlink service data flow is the same, and the identification process is performed simultaneously. The present invention conducts deep packet detection and recognition on the frame data of the service data flow, and carries out deep flow detection and recognition on unrecognizable encrypted services, and the granularity of recognition is frames, and comprehensively utilizes DPI and DFI recognition technologies to detect bidirectional business data All flows are identified, which improves the efficiency of business data flow identification.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for bidirectional service data flow identification. Background technique [0002] With the rapid development of Internet services, various new Internet services emerge in an endless stream, such as P2P (Peer to Peer, peer-to-peer network) services, webpage video services, instant messaging services, VoIP (Voice over Internet Protocol) services, streaming media services , online game business, etc. P2P services and various video services consume a large amount of bandwidth, making operators have to expand the backbone network. However, the income of operators has not increased with the expansion of the network. It is necessary for operators to change the network management method and introduce intelligent technology to tap the potential value of the network. It is the general trend to identify various services in the network and perform refined managem...
