Problems solved by technology

Usually, there is always a difference in the speed of the sending end and the receiving end. If the speed of the sending end is higher than that of the receiving end, there will be a data overflow problem, which will cause data loss; Incorrect data; and in terms of speed, a mechanism is needed to adjust the sending and receiving speed according to demand

Embodiment Construction

[0043] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0044] refer to figure 1 , figure 1 It is a schematic flow chart of a preferred embodiment of the flow control method of the present invention, the method includes:

[0045] S10. The flow control device obtains the writing speed V1 of the sending end, the reading speed V2 of the receiving end, the transmission speed V set by the user, the capacity L of the data queue in the cache module in the flow control device, and the used data queue size E.

[0046] The flow control device is respectively connected with the sending end and the receiving end, and is used for controlling the data transmission speed between the sending end and the receiving end.

[0047] The flow control device includes a cache module, and the data in the cache module is stored in the form of a data queue, and the capacity L of the data queue doe...

Abstract

Disclosed are a traffic control method and device, and a computer storage medium. The traffic control method is applied to a traffic control device. The method comprises: respectively acquiring a writing velocity V1 of a sending end, a reading velocity V2 of a receiving end, a transmitting velocity V set by a user, and a capacity L of a data queue of a cache area of the traffic control device itself and a used capacity E of the data queue; and according to the writing velocity V1, the reading velocity V2, the transmitting velocity V, the capacity L and the used capacity E, controlling the start timer and the stop timer for the sending end to write data into the cache area and / or controlling the start timer and the stop timer for the receiving end to read data from the cache area.

Description

technical field [0001] The present invention relates to the communication field, in particular to a flow control method and device. Background technique [0002] In the current communication system, there is end-to-end massive data transmission between layers of data service protocols, between modules in the same system, and between two nodes of a local area network or wireless network. Usually, there is always a difference in the speed of the sending end and the receiving end. If the speed of the sending end is higher than that of the receiving end, there will be a data overflow problem, which will cause data loss; Incorrect data; and in terms of speed, a mechanism is needed to adjust the sending and receiving speed according to demand. Therefore, how to provide a reliable flow control method to prevent data transmission overflow and perform speed control will be an urgent problem to be solved. Contents of the invention [0003] The main purpose of the present invention...
