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.

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.

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.

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.
摘要:
Verfahren zur Energieeinsparung durch schnelle dynamisch angepasste Änderung der jeweiligen Bitraten in einer sternförmigen Netzinfrastruktur mit einem zentralen Knoten, der mit einem oder mehreren Endknoten verbunden ist, wobei die Endknoten mit dem zentralen Knoten ausschließlich mit einer Datenrate gemäß einem beliebigen ganzzahligen Teiler der Maximaldatenrate kommuniziert, die kleiner oder gleich der Maximalbitrate ist und an den jeweiligen Bedarf angepasst werden kann. Die Datenraten der einzelnen Verbindungen zwischen zentralem Knoten und jeweiligem Endknoten können hierbei im Extremfall alle verschieden sein.

While continuously providing a service in an existing optical communication system, a service at another communication speed is realized at low cost. For this reason, a station-side optical network terminal apparatus is configured so that to one light-emitting unit connected are a first processing unit that performs a process to output an optical signal at one communication speed by the light-emitting unit and a second processing unit that performs a process to output an optical signal at another communication speed by the light-emitting unit.
