Experimental assessment of ABNO-based network orchestration of end-to-end multi-layer (OPS/OCS) provisioning across SDN/OpenFlow and GMPLS/PCE control domains

We present and experimentally assess in an international testbed an ABNO-based network orchestrator for end-to-end multi-layer (OPS and Flexi-grid OCS) and multi-domain provisioning across heterogeneous control domains (SDN/OpenFlow and GMPLS/Stateful PCE) employing dynamic domain abstraction based on virtual node aggregation.
