A transmission bandwidth control method, device and system

Abstract

Disclosed is a method for controlling a transmission bandwidth, comprising: receiving a bandwidth request of a service application device, wherein the bandwidth request carries an applied bandwidth value; and according to the applied bandwidth value, for the service application device, from all physical ports of the same resource pool, selecting a physical port of which the usage state is available, the unallocated bandwidth is not less than the applied bandwidth value, and the number of unallocated logical ports is greater than 0, allocating a logical port of which the usage state is unallocated under the physical port, and setting a bandwidth value of the logical port of which the usage state is unallocated as the applied bandwidth value. By means of the technical solution of the present invention, the system bandwidth can be dynamically used according to actual service demands of a service application, thereby improving the utilization rate of the system bandwidth.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a transmission bandwidth control method, device and system. Background technique [0002] Existing base stations generally include one to two indoor baseband processing units (BuildingBaseBandUnit, BBU), and the base station uses physical ports on the BBU for data transmission. [0003] In order to achieve independent control when different business applications use the bandwidth of the same physical port, multiple logical ports are created on the physical port, and the bandwidth is set for each logical port. Different business applications use different logical ports to realize the use of bandwidth by different business applications. control to prevent multiple business applications from competing for bandwidth resources on the same physical port. During the research and practice of the existing technology, the inventors of the present invention found that the sh...

Problems solved by technology

During the research and practice of the existing technology, the inventors of the present invention found that the sharing of physical ports by existing base stations is realized by manually pre-configuring logical ports. In the case of large BBU scale and application scale, manual The workload of configuration is relatively large, and the amount of bandwidth required by different applications needs to be estimated in advance. The amount of bandwidth needs to be planned according to the maximum value that may be required by the application. When different applications have tidal phenomena in bandwidth requirements, port bandwidth resources waste of
