The control of Multi-domain Elastic Optical Networks (EON) is possible by combining H-PCE based computation, BGP-LS topology discovery, remote Instantiation via PCEP, and signaling via RSVP-TE. This paper presents the first multi-platform demonstration that fully validates such control architecture achieving multi-protocol interoperability.
This paper demonstrates an experimental Virtual Machine (VM) migration across several network domains (intra/inter-datacenter) while the VM network connection state is maintained. A SDN IT and Network Orchestrator is responsible for the VM seamless migration.
We present an integrated IT and network orchestration using OpenStack for the deployment of virtual machines within DCs and OpenDaylight SDN controller for end-to-end connectivity provisioning across Ethernet networks (Intra-DC) and a GMPLS-enabled WSON with an active stateful PCE (Inter-DC).
We propose a Transport PCE architecture to deploy a Transport PCE by means of Network Function Virtualization. Virtual PCEs are deployed on demand, but they are perceived as a single Virtualized Network Function. We present the benefits by experimental validation.
