Problems solved by technology
[0004] The existing flow control system adopts the flow control method of initial authentication and fixed-frequency authentication, which will not only cause the flow control policy of the flow transmission request initiator to be updated, but cannot be fed back to the flow transmission device in time, but will also lead to inaccurate flow control; In addition, there are too few or too many interactions between traffic control policy requests and responses, which affects the quality of traffic transmission and causes the traffic control system to be too busy or idle, and the control policy needs to be recalculated every time it is updated. This also consumes a lot of resources. the computing power of the system

Embodiment Construction
[0042] In the embodiment of the present invention, when the traffic data is collected and it is determined that the control strategy does not exist or is invalid, a control strategy update request is sent to determine whether the current control strategy exists or is valid. When the current control strategy exists and is valid, the characteristics of the current control strategy are judged Whether the value is consistent with the characteristic value of the control strategy of the latest response. If it is consistent, resend the control strategy of the latest response; if it is inconsistent, send the current control strategy and update the control strategy of the latest response as the current control strategy; When it exists or is invalid, recalculate the control strategy, and update the current control strategy to the newly calculated control strategy.
[0043] Further, after the current control strategy is updated to the newly calculated control strategy, a control strategy ...

The invention discloses a flow control method, comprising: collecting flow data; when it is determined that the control strategy does not exist or is invalid, sending a control strategy update request, and judging whether the current control strategy exists or is valid; when the current control strategy exists and is valid, judging Whether the eigenvalue of the current control strategy is consistent with the eigenvalue of the latest response control strategy, if it is consistent, resend the control strategy of the latest response; if it is inconsistent, send the current control strategy, and update the control strategy of the latest response to the current control strategy ; When the current control strategy does not exist or is invalid, recalculate the control strategy and update the current control strategy to the newly calculated control strategy. The invention also discloses a flow control system at the same time.
Description
technical field [0001] The present invention relates to flow control technology in the communication field, in particular to a flow control method and system. Background technique [0002] Network traffic is a collection of data transmitted by a communication network, including voice calls in the circuit domain, data traffic in the packet domain, and so on. Flow control indicators such as the size of traffic data and the speed of transmission rate are closely related to the operating income of the network or service provider. [0003] There are usually two current flow control methods: one is the initial authentication, when the flow transmission device receives the flow transmission request, it reads the flow control parameters preset by the flow transmission request initiator stored in the flow control center, and passes Control the traffic sending rate or limit the number of traffic transmissions to achieve the purpose of traffic control. Only when the traffic transmissi...
