Problems solved by technology

This simple control method based on the CAR value can no longer meet the user's requirements for the quality of service of the network provider
Devices based on Deep Packet Inspection (DPI) can control traffic without using the CAR value control method, but the processing capacity of a single DPI device cannot meet the needs of the live network, and cannot make overall judgments
When the DPI device controls the flow, it cannot target the special flow, thus affecting the flow of the user's normal business

Embodiment Construction

[0029] The embodiment of the present invention provides a network flow control method and system, a DPI device and a policy center. In order to make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0030] see figure 1 , is a signaling flow chart of an embodiment of the network flow control method of the present invention, and the specific flow for realizing flow control includes:

[0031] Step 101: the DPI device identifies traffic, and counts various traffic information;

[0032] There can be multiple DPI devices, and the traffic in the backbone network is distributed to each DPI device, and each DPI device collects detailed statistics on the traffic information of its branch. For example, various traffic information such as total uplink traffic, total downlink traffic, uplink sub-protocol traffic, downlink sub-protocol traffic, total uplink tr...

Abstract

The embodiment of the invention discloses a network flow control method and a corresponding system and a device. The network flow control method comprises the steps that: a strategy center resolves flow information calculated by a DPI device according to the content of a received deep packet to calculate the total network flow, and formulates a corresponding flow control strategy according to the total network flow and sends the corresponding flow control strategy to the DPI device; the DPI device obtains a corresponding flow threshold value of the next predetermined period of time according to the flow control strategy; the DPI device controls the flow when the flow passing through the DPI device exceeds the flow threshold value. By the technical proposal provided by the embodiment of the invention, the strategy control center can formulate different flow control strategies according to the specific flow information calculated by the DPI device, and therefore selective control over service flow can be carried out, which has no effect on the normal service of users.

Description

technical field [0001] The invention relates to the technical field of data exchange, in particular to a network flow control method, device and system. Background technique [0002] With the expansion of network scale and the deepening of network applications, the flow of data transmission is also increasing. The application of computer resources and information sharing (P2P, Peerto Peer) software achieved through point-to-point direct exchange between systems has also caused network congestion. Operators, enterprise users, and users in education and other industries need to limit the flow of specific applications . Existing traffic control algorithms are all based on CAR (Committed Access Rate) value control. The core router or access device assigns a certain CAR value to each link or user. When the user traffic exceeds the CAR value, the Handle packet loss. [0003] During the research and practice of the prior art, the inventors of the present invention found that the...
