摘要： 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.

摘要： Optical networks may store information or data therein by maintaining the information or data in motion. The optical networks may include optical fiber rings configured to receive optical signals comprising the information or data and to circulate the optical signals within the optical fiber rings. The optical signals and the information or data may be transferred out of the optical fiber rings in order to amplify the optical signals (e.g., to overcome losses due to attenuation within the optical fiber rings), to analyze the optical signals according to one or more processing techniques, or to transfer the information or data to another computer device upon request. If continued storage of the information or data is required, an optical signal including the information or data may be transferred back into the optical fiber rings and may continue to circulate therein.

摘要： 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.

摘要： A bus-based optical network system comprising optical fibers, optical line terminals (OLTs), and a plurality of optical network units (ONUs) is revealed. The OLT consists of the near part (OLTN) and the far part (OLTF). Optical fibers respectively form the transmitting and receiver buses (T Bus and R Bus) with the technique of time-division multiple access (TDMA). The slot flows on both buses are in opposite directions. The OLTN performing traffic control is situated in or near a central office (CO) while the OLTF is far from the CO. ONUs, whose MAC performs traffic control, connect with two buses and share their bandwidth. The MAC with traffic control keeps the performance of the network from degradation. The required numbers of COs and optical fibers for establishing the bus-based network are so smaller that the cost of the network can be significantly reduced.
