摘要： Systems and methods implemented by an all-optical switch configured to switch signals optically in an optical network include receiving and processing call information from a messaging/signaling session, wherein the call information relates to one or more calls on ports in the all-optical switch; and configuring the ports in the all-optical switch in the network based on the processed call information. The call information can include detection of one of a fault and a lockout on the one or more ports and an indication of faults in the optical network. One of a control plane and an SDN controller can be connected to the all-optical switch via the messaging/signaling session.

摘要： Systems and methods for controlling an optical switch via one of a control plane and Software Defined Networking (SDN) include associating one or more managed endpoints with one or more line ports of an optical switch; receiving state information for the one or more managed endpoints over a session associated with one of the control plane and the SDN; and controlling switching of the one or more line ports based on the state information for the one or more managed endpoints. The optical switch is an all-optical device which does not have access to digital signal quality information of associated signals.

摘要： Systems and methods of flexible behavior modification of a service implemented in a node during restoration in an optical network include provisioning the service on a home route with a first set of attributes; defining one or more protect routes in the network for the service, wherein each of the one or more protect routes have a corresponding set of attributes which differs from the first set of attributes; and, responsive to restoration of the service, determining a protect route of the one or more protect routes to restore the service and changing the service to have the corresponding set of attributes while on the protect route.

摘要： A method of managing an optical communication network having a plurality of nodes, the plurality of nodes including at least one regeneration site. A respective Path Computation Element (PCE) function is instantiated and associated with each regeneration site in the network. Each PCE function maintains a reach table containing information of viable optical paths extending from transceivers of its regeneration site. The PCE function implements a Recursive Path Computation algorithm to compute end-to-end routes through a physical layer of the network.

摘要： In an embodiment, a user equipment (UE), establishes a local connection (e.g., USB, Bluetooth, etc.) to a network infrastructure device (e.g., a network switch or router) that is not yet configured for operation on a communications network. The UE obtains, while connected to the network infrastructure device over the local connection, device-identifying information (e.g., a location of the UE, a pre-provisioned identifier for the network infrastructure device, etc.) by which the network infrastructure device can be distinguished from other network infrastructure devices of the same type. The UE loads a configuration installation file that is specially configured for the network infrastructure device based on the obtained device-identifying information. The UE executes the configuration installation file over the local connection to configure the network infrastructure device for operation on the communications network.

摘要： A method for executing a network command using synchronized timers. The method includes obtaining, by a first device, a first current time value from a first timer of the first device, determining, by the first device, a time-to-execute value based on the first current time value, sending, from the first device to a second device, a first network command message including the network command and the time-to-execute value, repetitively obtaining, by the second device, a second current time value from a second timer of the second device, comparing, by the second device and in response to receiving the first network command message, the second current time value to the time-to-execute value extracted from the first network command message, and executing, by the second device and in response to the second current time value matching the time-to-execute value, the network command, wherein the first timer and the second timer are synchronized.
