1. A processor-implemented method for use in performing a circuit transition in accordance with an optical ring-based network, comprising the steps of:

  • obtaining a first circuit layout and a second circuit layout for a given set of demands to be routed on the optical ring-based network; and

    calculating by a processor a transition sequence plan useable to transition the network from the first circuit layout to the second circuit layout such that substantially no network service disruption occurs due to the circuit transition;

    wherein the transition sequence plan is calculated by determining a minimum set of circuits that when moved from first positions in the first circuit layout result in a feasible transition sequence for remaining circuits in the first circuit layout.
