Abstract
A method and system for changing the extent of data plane resources controlled by a control plane for a network connection which spans a contiguous set of nodes controlled by existing network control resources is disclosed. This is done in a non-disruptive manner. This typically involves two steps: i) Creating a new set of control plane resources for said network connection such that said data plane resources are shared with said existing network control resources; and ii) then terminating the existing network control resources such that said data plane resources are fully transferred to the new set of control plane resources without disrupting said network connection. The existing network control resources can be either a control plane resource or a non control plane resource. An example of a non control plane resource is network management software (e.g., an OSS (Operation Support System)), which forms part of the Management Plane. It should be noted that this does not need to be done for a complete end-to-end connection, but rather can be executed for the portion of the end-to-end connection which is to be controlled by the control plane.
