Abstract: The disclosure provides a method for bandwidth assignment of an Optical Burst Ring (OBRing), which includes that: a master node acquires current bandwidth resources, and excludes bandwidth resources occupied by over-the-master-node connections from the current bandwidth resources to obtain bandwidth resources to be assigned; and the master node assigns the bandwidth resources to be assigned to each node according to bandwidth requests of each node in the OBRing. The disclosure also provides a device for bandwidth assignment of an OBRing. According to embodiments of the disclosure, the bandwidth resources occupied by the over-the-master-node connections are excluded before bandwidth assignment is started, so that the problem of receiving conflict caused by an over-the-master-node service data connection is solved.

Abstract: Embodiments of the present disclosure disclose a dynamic bandwidth scheduling method and device, and a computer storage medium. The method is applied to each node in an Optical Burst Transport ring-Network (OBTN) and includes that: when a target node serves as a master node, for each source node in the OBTN, when a timeslot is allocated for a connection from the source node to a certain destination node, a timeslot occupied by a destination node having the smallest hop count to a destination node configured currently is selected preferentially among timeslots in which there exists an Optical Burst (OB) where there has been no drop operation; and when the target node serves as a master node, a timeslot allocation result is converted into a bandwidth map and the bandwidth map is sent to each slave node in the OBTN.
