摘要： Techniques are provided to automatically configure packet based network services over Dense Wavelength Division Multiplex (DWDM) network communication links. An optical wavelength is detected at an optical interface of a network device configured to send traffic between a packet switched network and an optical network. A message is sent to an optical control plane comprising information configured to request optical configuration information for the optical wavelength. A response to the message is received comprising the optical configuration information and the wavelength is activated at the optical interface using the optical configuration information. A frame is received over the wavelength that is formatted according to an optical protocol. Packet switched network information is extracting from an overhead portion of the frame that is configured to identify network parameters for configuring a packet switched network link and the associated routing. The packet switched network link is configured using the network parameters.

摘要： Diversity constraints with respect to connections or links in a client layer are conveyed to a server layer where those links or connections are served by paths in the server layer. A network device in the server layer stores data associated paths in the server layer with identifiers for connections in the client layer. The network device in the server layer receives from a network device in the client layer a request to set up a path in the server layer for a connection in the client layer. The network device in the server layer receives information describing the diversity requirements associated with connections in the client layer. The server layer network device computes a route in the server layer for the connection specified in the request based on the diversity requirements.

摘要： Techniques are provided for using light path priority of service information in an optical network. At a node in the optical network, priority of service information is stored for a plurality of light paths used in the optical network. The node serves traffic in the optical network using the plurality of light paths based on the priority of service information. These techniques provide for prioritizing light paths (wavelengths) for scenarios such as restoration, congestion and resource contention.

摘要： A reconfigurable WDM add/drop multiplexer and its method of operation at an add/drop node on an optical fiber carrying a plurality of WDM signals is described. The WDM add/drop multiplexer has a coupler and a demultiplexer element dropping WDM signals from the optical fiber to a plurality of drop terminals, and a wavelength-selective switch adding WDM signals from a plurality of add terminals onto the optical fiber. The coupler splits the WDM signals received from the optical fiber and passes the split WDM signals to the first and second output terminals. The demultiplexer element separates the split WDM signals at the plurality of drop terminals. The wavelength-selective switch, which has an input terminal for connection to the second coupler output terminal and an output terminal for connection to the optical fiber, selectively adds WDM signals on the plurality of add terminals to the optical fiber responsive to control signals.

摘要： In one embodiment, first optical signal can be generated at a first end of an optical fiber segment at a first time. The first optical signal can be detected at a second end of the optical fiber segment at a second time.

The second optical signal can be detected at the first end of the optical fiber segment at a fourth time. A length of the optical fiber segment can be determined based on a difference between the second time and the first time, a difference between the third time and the second time, and a difference between the fourth time and the third time.
