1. A method of estimating photonic service capacity change speed along an optical transport path in an optical network, the method comprising:

  • determining first available margins of all existing first services actively provisioned along the optical transport path according to a then present optical loading condition along the optical transport path;

    readjusting each first available margin by a first additional margin penalty each first active service would incur when the photonic service capacity would be changed along the optical transport path;

    obtaining a path margin from the readjusted first available margins;

    determining a maximum path allowable power offset from the path margin; and

    indicating photonic controller settings which would generate less than the maximum path allowable power offset for all first active services along the transport path during the photonic service capacity change for network planning a non-service affecting photonic service capacity change.
