Abstract
A Make-Before-Break (MBB) method, in a node operating in a network with a control plane, decoupling the control plane from a data plane, includes, for a connection operating on a path in the network, determining a reserved connection on a new path, through the control plane, wherein the reserved connection has zero bandwidth; signaling the reserved connection on the new path; creating the reserved connection in the control plane while suspending implementation in the data plane due to the zero bandwidth; and releasing the connection on the path and modifying the reserved connection on the new path to establish the connection on the new path.
