    Abstract: A method and apparatus for optimizing optical transport using a software defined network (SDN) controller are disclosed herein. The SDN controller may define a margin optimization function based on at least one optical system performance metric. The function may include at least one related initiation criterion. Further, the SDN controller may collect at least one measurement for the performance metric. The measurement may include an assessment of deployed carriers not carrying client data. The SDN controller may determine whether the initiation criterion is met based on at least one collected measurement. The SDN controller may select a system margin optimization mechanism and define a system margin optimization threshold criterion on a condition that the initiation criterion is met. The SDN controller may determine whether the optimization threshold criterion is met. The SDN controller may implement one or more optimization events on a condition that the optimization threshold criterion is met.

  • Patent number: 9949003
    Abstract: Systems and methods for a multi-layer network to achieve network resource isolation among clients using the same server network, such as a VPN in a multi-layered network and interaction within the node, may include interaction between a server layer (e.g. L0 Photonic network) and the client layer (e.g. L1 network) that help the client layer (L1) gather information about the server-layer (L0) connection affinities. For example, the use of server layer (L0) connection affinities to construct Virtual Network Topologies (VNT) and/or network abstractions for customer traffic isolations in client layer (L1), the use of VNT to offer physical and/or logical network resource isolation for L1 customers, and provide L1 VPN services in a multi-layer environment.

  • Patent number: 9831942
    Abstract: A method for receiving, by circuitry of an optical node adapted for wavelength multiplexing and wavelength switching, over an OSC an optical signal comprising overhead information indicative of status of at least one of an optical layer in an OTN; terminating the optical signal; notifying software of the status of the optical layer; detecting, based on the status of the optical layer, a uni-directional or bi-directional failure of a working path between the optical node and a second optical node, wherein the working path carries data traffic from the first optical node to the second optical node in the OTN when there is no failure in the working path; and switching, triggered by the uni-directional or bi-directional failure of the working path, to select the data traffic from a protection path, wherein the protection path carries data traffic between the optical node and the second optical node.

  • Patent number: 9800495
    Abstract: A method, performed in a network that includes a group of nodes, includes identifying a path through a set of the nodes, where each node, in the set of nodes, has a data plane and a control plane; establishing a control plane tunnel, associated with the path, within the control plane of the nodes in the set of nodes; establishing a data plane tunnel, associated with the path, within the data plane of the nodes in the set of nodes, where the data plane tunnel is associated with the control plane tunnel and established through the same set of nodes; and transmitting a control message through the control plane tunnel to change a state of the data plane tunnel.
