Embodiment Construction

[0020] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0021] In the embodiment of the present invention, by receiving the rate limiting type information for limiting the rate of the data stream, it matches the current data packet corresponding to the rate limiting type. In the current time period, when the packet length of the current data packet is greater than the amount of data currently allowed to pass, The current data packet is discarded, thereby realizing the flow control of the data flow corresponding to the speed limit type, and greatly reducing the difficulty of implementing the speed limit on the data flow.

Abstract

The invention is applied to the technical field of flow control, and provides a method and device for limiting the speed of data flow. The method for limiting the speed of data flow comprises the steps that speed limiting type information for limiting the speed of the data flow is received, wherein a speed limiting type comprises a broadcasting speed limiting type or a multicast speed limiting type or a unicast speed limiting type; the current data package corresponding to the speed limiting type is matched, and the package length of the current data package is obtained; the time difference between the current moment and the last recording moment is calculated, the last recording moment is the starting moment of the current time quantum, and the duration of the current time quantum is assigned time; if the time difference is smaller than the assigned time, and the package length of the current data package is larger than the current data size allowed to pass through, the current data package is discarded. According to the method and device for limiting the speed of the data flow, the mode of carrying out speed limiting on the data flow without being based on the queue is achieved, the achieving difficulty for traditional speed limiting on the data flow is lowered greatly.

Description

Technical field [0001] The invention belongs to the technical field of flow control, and in particular relates to a method and a device for limiting data flow. Background technique [0002] With the rapid development of network technology, there are more and more network terminal devices, and users' demands on the network are also increasing. Although network operators are increasing the uplink bandwidth every year, the rate of increase of their uplink bandwidth is far less than the increasing demand for network speed by the majority of users. Assuming that the bandwidth of a certain network intermediate device is 10Mb / s, when user A uses BitTorrent (also known as BitTorrent or BT), video transmission or other data transmission functions that require large traffic, the 10Mb / s upstream bandwidth will be occupied by user A Most or even all, resulting in poor network service quality for other users or even unable to obtain network services. [0003] Therefore, for multi-user Interne...
