    Abstract: Embodiments relate generally to systems and methods for transitioning a system from a tradition network to a Software Defined Network (SDN) enabled network. In some embodiments, the systems and methods may comprise the use of a Path Computation Element (PCE) as a central controller. Smooth transition between traditional network and the new SDN enabled network, especially from a cost impact assessment perspective, may be accomplished using the existing PCE components from the current network to function as the central controller of the SDN network is one choice, which not only achieves the goal of having a centralized controller to provide the functionalities needed for the central controller, but also leverages the existing PCE network components.

    Abstract: Embodiments are provided herein to enable single level network abstraction for a service across one or more domains. The embodiments use a single network ID to identify a service and a corresponding virtual network topology across any number of domains at a physical network. A virtual network topology can be abstracted for each service, based on the physical underlying network topology. A network controller determines, for a service, the virtual network topology within a physical network, and binds the service to the virtual network topology via a virtual network ID, which defines a single forwarding domain of the virtual network topology across the physical network. The virtual network ID is then indicated to the nodes of the virtual network topology, thus enabling the nodes to identify and forward traffic for the service, within the single forwarding domain, between end clients from edge to edge of the physical network.

    Abstract: In one aspect, the invention includes, in a root node along a secondary label switching path, a computer program product comprising computer executable instructions stored on a non-transitory medium that when executed by a processor cause the root node to perform the following: establish a first data plane based failure detection session having an inactive status along a first label switching path (LSP) with at least one leaf node, receive a predetermined number of notification messages from the leaf node, wherein the predetermined number of notification messages indicate the failure of a second data plane based failure detection session along a second LSP from a second processor to the leaf node, and change the status of the first data plane based failure detection session to active along the first LSP upon receipt of the predetermined number of notification messages.
