    摘要: The present invention discloses a method, an apparatus and a system for processing a TDM service, where the method includes: receiving, by an OLT, a TDM packet that an ONT sends by using a valid payload; learning, by the OLT, an encapsulation mode of the TDM packet; switching, by the OLT, a forwarding model according to the encapsulation mode of the TDM packet, so as to implement centralized uploading of a TDM service. Corresponding to the method, the present invention further discloses a corresponding apparatus and system for processing a TDM service. The present invention can simplify a process of configuring a forwarding model on the OLT and implement flexible provisioning of a TDM service.

    摘要: A network component comprising at least one processor configured to implement a method comprising collecting wavelength availability information associated with a wavelength switched optical network (WSON), receiving a path computation request to transport a signal through the WSON, calculating at least one route through the WSON for the signal, and assigning at least one wavelength for the signal to use along the route. Also disclosed is a network comprising a first path computation element (PCE) configured to compute at least one route for a signal between a source and a destination, and a second PCE in communication with the first PCE, wherein the second PCE is configured to receive the route from the first PCE and assign at least one wavelength to the route.

    摘要: In a first aspect, the method and apparatus of the present disclosure can be used to periodically and/or intermittently place one or more ONUs attached to a PON in a power savings mode so that an OTDR test can be performed. While in the power savings mode, the ONUs temporarily suspend their transmitter function and power down their upstream lasers. In a second aspect, the method and apparatus of the present disclosure can be used to coordinate the performance of OTDR during one or more periodic or intermittent discovery slots used to detect and register ONUs recently connected to the PON. Because new ONUs are infrequently connected to the PON and ONUs already registered are not permitted to transmit during the discovery windows, OTDR can be performed during these windows without impacting, to a great degree, the normal operation of the PON.

    摘要翻译: 在第一方面,本公开的方法和装置可以用于周期地和/或间歇地将附接到PON的一个或多个ONU放置在省电模式中,从而可以执行OTDR测试。 在省电模式下,ONU暂时停止其发射功能并关闭其上行激光器。 在第二方面,本公开的方法和装置可用于协调在用于检测和注册最近连接到PON的ONU的一个或多个周期性或间歇发现时隙期间OTDR的性能。 由于新的ONU不经常连接到PON,并且在发现窗口期间不允许发送已经注册的ONU,因此可以在这些窗口中执行OTDR,而在很大程度上不会影响PON的正常运行。

    摘要: The present invention discloses a method for assigning and processing a label in an optical network, an optical communication device, and an optical communication system, capable of assigning labels for an OTN network supporting different signal types and tributary slot types. The method includes: learning that a label switched path is required to be established in an optical network; generating a label according to a signal type of the label switched path and network resources, in which the label is used for indicating that a first optical channel data unit is multiplexed to a second optical channel data unit; the label includes a tributary slot type indication field that is used for indicating a tributary slot type of the second optical channel data unit, and the label further includes a tributary slot assignment indication field that is used for indicating a tributary slot occupied in the second optical channel data unit into which the first optical channel data unit is multiplexed; and sending the label to a node on the label switched path by a signaling message of General Multi-Protocol Label Switching. The present invention further provides a corresponding optical communication device and optical communication system.
