摘要： A network includes multiple nodes interconnected to form a ring topology. These nodes support data transmissions over the network using tokens. To send and receive data over the network, nodes may process control messages. A node can receive a first token authorizing transmission on one of multiple data channels, generate a transmission control message identifying a destination node and the authorized data channel, and communicate the transmission control message to a next node. The node can also communicate a second token to the next node authorizing secondary transmissions on the authorized data channel, transmit data on the authorized data channel after communicating the transmission control message, and communicate the first token to the next node after communicating the second token to the next node.

摘要： Systems and methods use single-fiber optical add/drop multiplexers (OADMs) to enable bi-directional data transmission in WDM systems over a single fiber. By reducing the required capacity for an optical network from dual fibers to a single fiber, significant cost and bandwidth efficiencies are achieved. The systems and methods also provide redundancy protection in single-fiber bidirectional line ring systems. In the event of a downstream fiber or device failure, the OADM module receives a signal on a first wavelength from a first direction, shifts the signal from the first wavelength to a second wavelength, and sends the signal back down the fiber it originated from on the second wavelength, thus maintaining the propagation of the signal in the ring system.

摘要： An optical transmission system that offers more efficient bandwidth usage in normal operation, as well as enhanced fault tolerance for higher service availability. A transponder converts high-priority and low-priority client signals into high-priority and low-priority wavelength signals to be added to network traffic. An optical switch fabric normally delivers high-priority and low-priority wavelength signals to high-priority and low-priority paths, respectively, where the two paths run in opposite directions. Such signals and paths are prioritized in terms of survivability against network failure. In case of a network failure, the optical switch fabric performs protection switching in either duplicate switching mode or path switchover mode depending on network failure information and drop wavelengths of each optical transmission device. In duplicate switching mode, high-priority wavelength signals are directed to both the high-priority and low-priority paths. In path switchover mode, they are routed to the low-priority path, instead of the high-priority path.
