Abstract

The invention relates to a bandwidth scheduling method and device. The method comprises the following steps: determining at least one link forming a first path when loading the first path in a network; acquiring path actual available bandwidth of each link in at least one link occupied by the first path; identifying whether the path actual available bandwidth satisfies the demand occupied bandwidth of the first path, if the path actual available bandwidth does not satisfy the demand occupied bandwidth, distributing the bandwidth for the first path from residual distributable bandwidth of eachlink in at least one link. According to the bandwidth scheduling method and device provided by the invention, the bandwidth can be distributed for the path according to the path attributed of the loaded path, the standby path occupied bandwidth can be dynamically reduced, the use ratio of the bandwidth is improved under the condition of guaranteeing the disaster recovery effect as much as possible, so that the network can bear more data stream service.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a bandwidth scheduling method and device. Background technique [0002] Service flow refers to the traffic in the network that includes identifying attributes such as source node, source interface, destination node, and destination interface, and some custom attributes. For example, traffic carrying voice conference services and traffic carrying video communication services can be regarded as one service flow. The data flow refers to abstracting a service flow in the network into a data flow within a software-defined network (English: Software Defined Network, SDN for short) controller. [0003] Usually, in order to ensure uninterrupted service (also referred to as uninterrupted traffic) when a data flow path fails, multiple paths need to be selected for the data flow at the same time. For example, in order to achieve the effect of disaster recovery, two p...
