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.

Abstract: Provided are a method, a system and a node for implementing APS in an OBRing network. The method comprises: a master node and a slave node separately perform optical power monitoring on respective channels, and aggregate monitoring results to the master node; when determining, according to the monitoring results, that a fault occurs, the master node sends a switching operation instruction to the slave node; and the slave node performs a switching operation and enters a protection working state. With the disclosure, a protection switching mechanism is introduced to the OBRing, which implements the processing on fault and ensures the communication quality of the OBRing.

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: Disclosed are a method for prolonging the transmission distance of a passive optical network system and an optical line terminal. The method includes: acquiring each EDC tap coefficient corresponding to each ONU; and according to the each EDC tap coefficient corresponding to the each ONU, performing dispersion compensation respectively on an uplink signal sent from the each ONU. Thus the dispersion suffered by ONUs at different transmission distances can be pertinently compensated, so that the transmission distance of the system can be effectively prolonged.
