The present disclosure relates to controlling queue release in a network. In particular, the disclosure proposes a controller configured to obtain a state of each of a plurality of queues of a network node and determine, based on the states of the queues, whether the utilization of one or more queues exceeds one or more thresholds. If one or more thresholds are exceeded, the controller is configured to generate one or more new priority entries for one or more queues of the plurality of queues and provide the one or more new priority entries to the one or more queues of the network node. Further, the disclosure proposes a network node being configured to provide a state of each of a plurality of queues to a controller, and obtain one or more new priority entries for one or more queues of the plurality of queues from the controller.

Device and method for queues release and optimization based on run-time adaptive and dynamic internal priority value strategy

The present disclosure provides a point cloud encoding method and system, a point cloud decoding method and system, a point cloud encoder, and a point cloud decoder. A prediction mode of attribute information of a current point is determined through geometric information of a point in a point cloud, so that a determination process of the prediction mode is decoupled from a reconstruction process of the attribute information of the point in the point cloud, the two processes can be performed in parallel, and thus the efficiency of encoding and decoding is improved.
