A device may receive a first network topology message from a network device. The first network topology message may include first network topology information associated with the network device in a first set of fields of the first network topology message. The device may generate a second network topology message. The second network topology message may include second network topology information associated with the device in a first set of fields of the second network topology message. The first set of fields of the second network topology message may correspond to the first set of fields of the first network topology message. The second network topology message may include the first network topology information associated with the network device in a second set of fields of the second network topology message. The device may provide the second network topology message.

Topology information for networks

An apparatus includes a memory and a processor operatively coupled to the memory. The processor is configured to partition a set of ports of an optical multiplexer into a set of port groups including a first port group having a first set of ports and a second port group having a second set of ports mutually exclusive from the first set of ports. The processor is configured to associate the first port group with a first router and associate the second port group with a second router. When the optical multiplexer is operatively coupled to the first router and the second router, the first router is operatively coupled to the optical multiplexer via the first set of ports and not the second set of ports, and the second router is operatively coupled to the optical multiplexer via the second set of ports and not the first set of ports.

Methods and apparatus for logical associations between routers and optical nodes within a wavelength division multiplexing (WDM) system

A device may cause an optical signal to be transmitted via a network path. The device may receive, from a network device, a link layer discover protocol (LLDP) message. The LLDP message may include signal characteristic information regarding the optical signal. The device may adjust transmission of the optical signal based on receiving the LLDP message. The device may cause an adjusted optical signal to be transmitted via the network path based on adjusting transmission of the optical signal.

Signal characteristic information for networks

A method, computer software program, and system provides automatic selection of time slots in time-division multiplexed connections. A network is mapped, and source and destination nodes are selected, as well as a route between them. Appropriate time slots are selected in a time-division multiplexed signal between the selected nodes, and a connection between the two nodes is automatically created, based at least in part on information related to the selected routes and time slots.
