Embodiment 1

[0035] Embodiment 1, please refer to figure 1 It is a signaling flowchart of an embodiment of a flow control method of the present invention;

[0036] Step 101, the physical interface card counts traffic information, and reports the statistical traffic information to the control logic module;

[0037] According to the port processing capability and the current flow size, the physical interface card generates traffic information that can represent the current port congestion status by counting the total traffic passing through itself, and reports the traffic information to the control logic module. The traffic information can be for the total traffic passing through the same port.

[0038] Further, if the physical interface card has added functions, more fine-grained statistics of traffic information can be obtained, such as statistics by business (for the traffic occupied by a certain type of business), uplink traffic statistics, downlink traffic statistics, etc.; when the phy...

Embodiment 2

[0052] see figure 2 It is a structural diagram of an embodiment of a control logic module of the present invention;

[0053] The receiving unit 201 is configured to receive flow information reported by the physical interface card;

[0054] Specifically, the flow information received by the receiving unit 201 may be the flow information generated by the total flow through the same port collected by the physical interface card in real time.

[0055] A processing unit 202, configured to formulate a flow control strategy according to flow information and preset logic functions;

[0056] Further, the processing unit 202 also includes:

[0057] A comparing unit 2021, configured to compare the traffic indicated by the traffic information with a preset traffic threshold;

[0058] A formulating unit 2022, configured to formulate a traffic control policy indicating to suspend current low-priority business traffic when the traffic information indicates that the traffic is greater tha...

Embodiment 3

[0071] see image 3 It is a structural diagram of an embodiment of a traffic management module of the present invention;

[0072] The receiving unit 301 is configured to receive the flow control strategy sent by the control logic module;

[0073] The management unit 302 is configured to manage the corresponding traffic according to the traffic control policy.

[0074] After the receiving unit 301 receives the flow control policy, the management unit 302 restricts the flow indicated by the flow control policy. For example, the traffic control policy indicates that the traffic used by P2P software is limited, and the management unit 302 can suspend the P2P business; when the traffic control policy limits the total traffic passing through the port, the management unit 302 can limit the business traffic with lower priority (Restriction can be to suspend or reduce its flow rate) to ensure the normal use of higher priority services.

Abstract

The embodiment of the invention discloses a flow control method, comprising the following steps: a physical interface card counts flow information and reports the counted flow information to a control logic module which is capable of setting different logic functions; the control logic module generates flow control strategy based on the flow information according to preset logic functions and issues the flow control strategy to a flow management module; the flow management module limits corresponding flow of the physical interface card according to the flow control strategy. The embodiment of the invention also provides corresponding devices and systems. As the technical proposal of the invention adopts the control logic module to receive the flow information sent by the physical interface card and develops the flow control strategy according to the flow information, the technical proposal can alter the rule for developing the flow control strategy by changing the logic functions in the control logic module, thus facilitating the expansion of flow control modes.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a flow control method, device and system. Background technique [0002] With the continuous development of communication technology, in practical applications, due to the limited load capacity of the communication system, or for other reasons such as ensuring the quality of service, it is necessary to control the traffic. The current flow control method is mainly based on the flow information. When the flow information indicates that the flow is greater than the preset threshold, the flow is controlled. This is a main implementation method of service quality assurance in the data communication field. [0003] In the prior art, the flow control is mainly completed by the flow management module. The flow management module first obtains the congestion status reported by the physical interface card (idle, congestion or super congestion). When the congestion status is i...
