摘要： Embodiments of the present invention disclose a protection switching method, including: when a fault occurs on a working trail between a first end node and a second end node, sending, by the first end node, a first protection switching request message to an intermediate node, where a protection trail of the working trail includes the first end node, the second end node, and at least one intermediate node; and receiving, by the first end node, a second protection switching request message from the intermediate node, and switching service data to the protection trail for transmission, where one overhead frame of the first protection switching request message and the second protection request message includes at least two overhead information groups, and the overhead information group includes a request type field, a request signal identifier field, and a bridge flag field. One overhead frame of the first protection switching request message and the second protection request message can indicate overheads of two timeslots, so that overhead resource utilization is improved.

摘要： A selection and distribution circuit (13) is provided between N optical transceivers (11) and one PON control circuit (12). The selection and distribution circuit (13) selects the optical transceiver (11) corresponding to an upstream frame that time-divisionally arrives, thereby transferring the upstream frame opto-electrically converted by the transceiver (11) to the PON control circuit (12) and distributing a downstream frame from the PON control circuit (12) to each optical transceiver (11). A power supply control circuit (23) stops power supply to at least one of one of optical transceivers (11) that are not used to transfer the frame of the optical transceivers (11) and a circuit that is not used to transfer the frame in the selection and distribution circuit (13). This can reduce the system cost per ONU in the optical transmission system.

The method includes: receiving, by a first optical network unit, synchronization data that is transmitted by a first optical line terminal through a GEM port corresponding to a predetermined GEM port ID or a logical link corresponding to a predetermined LLID, and storing the synchronization data; and when a fault occurs on the first optical line terminal or on a backbone optical fiber connected to the first optical line terminal, transmitting, by the first optical network unit, the synchronization data to a second optical line terminal so that the second optical line terminal recovers services according to the synchronization data. In the embodiments of the present invention, the problem in the prior art that the speed of data synchronization is slow between a master OLT and a standby OLT and the reliability is not high when a fault occurs on the master OLT or on a backbone optical fiber connected to the master OLT can be solved. In this way, the speed of data synchronization between the master OLT and the standby OLT is improved, and the reliability of data synchronization is ensured.

摘要： A system, device, and method for managing communication services in an optical communication system utilizes a optical service agent (OSA) (610) that operates within the domain of the network user and manages various communication services on behalf of the network user. The OSA interacts with the optical communication network (380) to obtain various communication services and manages those communication services for the network user based upon predetermined parameters defined by the network user. An authenticated auto-discovery mechanism is used to automatically identify and authenticate OSA-enabled users and to distribute information between peer OSA-enabled users. A peer-to-peer signaling mechanism is used to extend OSA functionality to OSA-enabled users that do not interfere directly with the optical communication network.
