The invention discloses a resource scheduling method and a controller and relates to the technical field of optical access network, wherein the method comprises the following steps that a controller obtains flow interaction information between the optical network units ONU; the controller determines the ONU pair of the cross-optical distribution network ODN interaction flow based on the flow interaction information between the ONUs; and the controller distributes the same wavelength resource, which is located at the same optical line terminal OLT, for the ONU pair of the cross ODN interactionflow; therefore, dynamic dispatching of the wavelength resource of the OLT is realized in a clustering OLT deploying scene, so that flow interaction between the ODNs and the load of the core router are reduced, and the utilization efficiency of the network resources is improved.
Description
technical field [0001] The invention relates to the technical field of optical access networks, in particular to a method and controller for resource scheduling. Background technique [0002] High-definition video, virtual reality, augmented reality and other service demands continue to stimulate the rapid growth of optical access network bandwidth. At the same time, traditional online video conferencing and file sharing and other P2P (Pear to Pear, end-to-end) services still occupy a large part of the access side. flow. In the future, the central office of the access network will need multiple large-capacity PON systems to be deployed in a centralized manner and perform bandwidth resource pool management to achieve the purpose of efficiently utilizing bandwidth resources on the access side. [0003] With the increase in the bandwidth demand of the optical access network, the demand for OLT cluster deployment is increasing. In a clustered OLT deployment scenario, how to im...
