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.
