Abstract

The invention provides an SDN network bandwidth control method and an SDN network bandwidth control system. The SDN network bandwidth control method comprises the following steps: setting one or more time slots, wherein each time slot is formed from beginning time to ending time; setting one or more node ranges, wherein each node range is formed from one beginning network node address to one ending node network address; setting a restricted bandwidth value corresponding to each of the time slots and / or the node ranges; obtaining current time, and determining whether the current time is located in the set time slots; obtaining current node, and determining whether the current node is located in the set node ranges; distributing bandwidth according to the restricted bandwidth value distributed in the current time where the time slot is located and the current node where the node range is located. Through software implementation and low cost, time-division and node-division bandwidth distribution is carried out according to the difference of different applications in corresponding positions of preset time slots and node ranges, so that the resources are flexibly distributed, network congestion and network redundancy are prevented, and the bandwidth availability ratio is effectively improved.

Description

technical field [0001] The present invention relates to the field of network technologies, in particular to a method and system for controlling bandwidth of an SDN network. Background technique [0002] The existing bandwidth control technology usually controls the bandwidth through the network layer or the application layer; however, the current bandwidth control technology at the network layer mainly limits the network speed through different protocols, and cannot control the available bandwidth of specific applications in detail , when the application sends large-scale data, it may impact other high-priority applications using the same protocol; the configuration through the hardware network layer is more complicated, and it needs to be configured on multiple network nodes to achieve full-path bandwidth control, and It is difficult to control in different time periods, and it is not flexible enough; the application layer network speed limit only provides a single speed li...
