An experimental demonstration of active stateful PCE for flexgrid networks is presented. The PCE enables elastic operations on established connections and, when required, performs hitless defragmentation of spectrum resources. Experimental assessment, including shifting of 400Gbps four sub-carrier superchannel is shown.
