For example, a method includes receiving, by the centralized controller, a discover message originating from a network node, which includes an intermediate node list that specifies a plurality of network nodes the discover message traversed from the network node to an edge node, determining, based on the plurality of nodes specified by the discover message, a path from the edge node to the network node, allocating each of a plurality of Multi-protocol Label Switching (MPLS) labels to a respective outgoing interface of each of the plurality of network nodes, and outputting one or more control messages for configuring the network node, wherein the control messages are encapsulated within a label stack comprising the allocated plurality of labels."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Dynamic control channel establishment for software-defined networks having centralized control","description":"Dynamic control channel establishment for an access network is described in which a centralized controller provides seamless end-to-end service from a core-facing edge of a network to access nodes.
