摘要： Techniques for updating configuration of an Optical Network Unit (ONU) in an Ethernet Passive Optical Network (EPON) include receiving a notification that an updated configuration file is available for the ONU, obtaining the updated configuration file, performing a first validation of the updated configuration file for structural errors, determining changes between a current configuration of the ONU and the updated configuration file to identify ONU resources to implement to the changes, performing a second validation about whether the ONU resources to implement the changes are available or not at the ONU and applying the changes to the ONU when it is determined that the ONU resources to implement the changes are available at the ONU.

摘要： The present invention discloses a ranging method for an optical network unit in a passive optical network, which includes: an Optical Line Terminal (OLT) performing ranging for an Optical Network Unit (ONU) in a operation state, updating an Equalization Delay (EqD) of the ONU according to a ranging result, and sending the updated EqD to the ONU; and the ONU implementing an upstream transmission synchronization according to the updated EqD. The present invention further discloses a ranging system for an optical network unit (ONU) in a passive optical network (PON), which includes a ranging device and an equalization delay updating device. In the present invention, the influence on the interruption of services of the ONU for which ranging is performed is reduced, and the time-sensitive services of the ONU for which ranging is performed are protected, thus improving the upstream transmission efficiency of the ONU.

摘要： A synchronized CDM communication system performs 1-to-N communication by CDM between a central office and first to N-th optical network units (ONU). The synchronized CDM communication system adds structural elements for realizing a connection state acquisition section to a conventional synchronized CDM communication system. A central office includes a presence check section, a ranging processing section and the connection state acquisition section. The presence check section checks the ONUs that are connected with the central office and the ONUs that are not connected. The ranging processing section performs transmission timing adjustments for the ONUs that are connected. The connection state acquisition section verifies whether all of ONUs are connected with the central office, and performs a discovery of a ONU, among the ONUs that were not connected at the time of the check, that has resumed participation in communication since the check ended.

摘要： The present disclosure provides systems and methods for rapid circuit provisioning in Optical Transport Networks (OTN) using signaling and routing protocols thereby enabling fast mesh restoration. The present invention utilizes a shim layer between OTN messaging (e.g., GCC or High-Level Data Link Control (HDLC)) and the associated signaling and routing protocol (e.g., OSRP, GMPLS, etc.). If an ODUk Connection CTP or TTP needs to be created, the shim layer runs a fast “OTN Setup” protocol, while buffering out going OTN messages. Incoming messages are still processed and do not require additional buffering. The purpose of the OTN Setup protocol is to allow the OTUk to re-frame on its client ODUk, while buffering out-going messages. When re-framing completes, buffers are released and the OTN messaging resumes without dropping any of the signaling frames.

摘要： A method and apparatus for regulating rogue behavior in optical transmission devices. The apparatus, for example, may be implemented in one or more of the ONTs in a PON. The ONT includes an optical transmitter that may be disabled by a command generated by the ONT itself if rogue behavior is detected or suspected. To detect rogue behavior, at least one output indictor, such as LBC or MPC, is monitored during one or more monitoring windows. If monitoring indicates that the optical transmitter is transmitting more than a pre-determined threshold, a suspect rogue flag is set, for example in an I2C register. The register is read, preferably a number of successive times, and a determination is made whether to disable the optical transmitter. In some embodiments, the OLT is queried as part of this determination. The disability may be permanent, until a manual service operation, for example, or temporary.

摘要： In an MPLS/GMPLS network, a link used by a communication path for each hop and adaptations used at the boundary between management domains or layers are appropriately and automatically selected according to a service type and a required maintenance condition, without making a control sequence complicated. First, a unit for requesting path establishment by including an identifier of a service to be provided and a service attribute in a communication path establishment control message is provided for a source node. Second, a unit for determining a required maintenance condition for a communication path and adaptations according to the service identifier and/or the service attribute is provided for each node. Third, links and nodes through which the communication path passes are determined by comparing each of achievable maintenance conditions for network resources with the required maintenance condition. The determined links, nodes, adaptations are specified as operation parameters in switches and/or interfaces.

摘要： In order to improve the link adjacency discovery in an Optical Transport Network, a method and related network nodes are provided. A first network node (21) has a first discovery agent (216) and a second network node (22) has a second discovery agent (226). A discovery message (210) is transmitted from a first interface of the first network node (21) over one or more subsequent network links (25, 26, 27) to a second interface of the second network node (22). The discovery message (210) contains information indicative of an discovery agent identifier associated with the first discovery agent (216) and of a termination connection point identifier associated with the first interface. In order to transmit the discovery message (210), the first interface is configured to perform a tandem connection source function (217) using a reserved field in an overhead portion of signal frames to be transmitted. The second interface is configured to perform a Tandem Connection Monitoring function (227) on the same reserved field of received signal frames. The discovery message is sent using a Trail Trace Identifier (TT!) byte available in the reserved field.
