Method and device for intelligent bandwidth allocation

Abstract

The invention relates to the technical field of network communication, and discloses a method and device for intelligent bandwidth allocation. The method includes: S1, in the initial stage, the upper limit of the bandwidth used by a user is not limited, and only the total amount of occupied bandwidth is recorded; S2, When the transmission speed no longer increases significantly, record the total amount of bandwidth occupied at this time as the real bandwidth; S3, lower the upper limit of the bandwidth for users whose bandwidth is greater than the average bandwidth to be slightly lower than the current bandwidth, The upper limit of the bandwidth of users whose bandwidth is less than the average bandwidth is not limited; S4, if the total amount of bandwidth occupied by the current network transmission is greater than the control value of the actual bandwidth, step S3 is repeated until the total amount of bandwidth occupied by the current network transmission is not greater than the actual bandwidth Bandwidth control value. The invention can ensure the maximum utilization rate of the bandwidth and realize the dynamic and reasonable allocation of the bandwidth without knowing the total bandwidth of the user by intelligently judging the total bandwidth and user requirements.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method and device for intelligent bandwidth allocation. Background technique [0002] For home, community or enterprise networks, it is often the case that multiple users share the same external port to access the Internet. At this time, multiple users share the external access bandwidth. The bandwidth of each user is allocated reasonably. [0003] The essence of bandwidth allocation in the prior art is to limit the bandwidth of each user. The traditional speed limit method mostly uses the TC (Traffic Control, Flow Control) technology that comes with the operating system kernel to set the bandwidth of each user one by one. bandwidth limit. Although the allocation method using the existing technology is relatively intuitive, because it limits the bandwidth of each user, when the sum of the actual traffic demanded by all users does not exceed the total bandwidth, ...

AI Technical Summary

Problems solved by technology

Although the allocation method using the existing technology is relatively intuitive, because it limits the bandwidth of each user, when the sum of the actual traffic demanded by all users does not exceed the total bandwidth, some users are often restricted from accessing, so it is not necessary The actual access efficiency of all users cannot be effectively guaranteed, and the actual utilization of bandwidth is also limited

In addition, TC technology controls the data packets forwarded outward, and can only limit the data flow transferred by other users. It cannot control the packets of the local machine (usually routers, gateways, etc.), and the actual bandwidth management may not be Accurate and reasonable

In addition, in the prior art method, the administrator must manually specify the bandwidth, the setting method is more mechanical, and the adjustment is more inconvenient. For the real-time dynamic changing user needs, it is difficult to accurately meet the requirements of each user
