摘要： A Make-Before-Break (MBB) method, in a node operating in a network with a control plane, decoupling the control plane from a data plane, includes, for a connection operating on a path in the network, determining a reserved connection on a new path, through the control plane, wherein the reserved connection has zero bandwidth; signaling the reserved connection on the new path; creating the reserved connection in the control plane while suspending implementation in the data plane due to the zero bandwidth; and releasing the connection on the path and modifying the reserved connection on the new path to establish the connection on the new path.

摘要： A method, in a node operating in a network with a control plane, to optimize wavelength retuning on service redials, includes detecting a failure on a link associated with the node; and, for each affected connections on the link, sending a respective release message to an associated originating node via the control plane, the release message including a protect path and a wavelength, wherein the release message is utilized by the associated originating node to redial the affected connections with the protect path and the wavelength determined by the node, to minimize wavelength retuning on the affected connections.

摘要： A localized repair method in a network using a control plane includes, responsive to a failure on a local repair segment defined on a connection traversing the network, generating a release message in the control plane; attempting a local repair on the local repair segment; if the local repair is unsuccessful, transmitting the release message to redial the connection; and, if the local repair is successful, signaling a new sub-path based on the local repair. A controller and a network are also disclosed.

摘要： Drop port based shared risk link group (SRLG) systems and methods assign SRLG information to drop ports in another level or layer of a network. Thus, drop side SRLG information can be shared between different networks or layers enabling a combination with line side SRLG information within a network to identify and prevent single points of failure across the networks. Typically, SRLG details are assigned to line ports (NNI ports) within a network and this information is not shared with external networks or network layers for routing a connection through the network and the external networks. By assigning SRLG details to a drop port, this information can be relayed between the network and the external networks and considered when planning a route through all of the networks.

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.

摘要： A method for managing network connections may include identifying a network failure within a network comprising various network elements. The method may include selecting, in response to identifying the network failure and for the network elements, a subset of nodal maps from various nodal maps. The nodal maps may be stored on the network elements. The subset of nodal maps may describe various cross-connections of the nodal maps within a first end-to-end connection in the network. The method may include transmitting, in response to selecting the subset of nodal maps, various activation requests to trigger the network elements to implement the subset of nodal maps.
