摘要： A computer program product comprising computer executable instructions stored on a non-transitory medium of an upstream node in a network system comprising a plurality of nodes that when executed by a processor cause the node to advertise an upstream assigned label to a downstream node, receive a message from the downstream node, and if the received message confirms that no conflict with the upstream assigned label exists at the downstream node, assign the upstream-assigned label, or if the received message confirms that a conflict with the upstream-assigned label exists at the downstream node, either select a new upstream-assigned label or wait until indication is received that the label resource has become available.

摘要： 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.

摘要： 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.
