An adaptive optical data center network architecture is, for the first time, proposed and simulated. Data center traffic loads are efficiently accommodated by FTP solution, supported by synthetic optical packet/circuit switching scheme and dynamic function-topology management.
We demonstrate an all-optical dynamic DCN utilizing a fully SDN-enabled data-plane including programmable FPGA-based NICs, offering Network Function Virtualization OCS/OPS driven multicasting for Virtual DC applications enabling link recovery and VM migration.
Application-based Network Operations consists of existing components offering an application-driven network management. We validate its applicability to multi-tenant networks in multi-technology optical domains based on congestion detection and failure recovery by demonstrating fast reconfiguration, while keeping the upper layer unaware.
We demonstrated an SDN-enabled optical DCN leveraging AoD, OPS, FPGA-based ToR with extended OpenDayLight controller and extended OF protocol. Experimental results show application-aware OCS/OPS connection provisioning (753/214ms), OPS end-to-end connections latency (252µs), and OCS/OPS switchover.
A new architecture utilizing combination of SDN and NFV for deeply programmable optical Internet infrastructure is proposed where network devices can be sliced, interconnected and programmed on demand for specific transport and network computing tasks.
We demonstrate a reconfigurable virtual datacenter network by utilizing statistical multiplexing offered by scalable and flow-controlled optical switching system. Results show QoS guarantees by the priority assignment and load balancing for applications in virtual networks.
An SDN-based control framework for OPS switches is experimentally assessed. The OpenFlow messages enabling control communication between SDN controller and OPS switch are validated. Dynamic OPS virtual network slices for intra-data center interconnect are successfully setup and monitored.
In a flattened optical data center network employing hybrid technologies, multi-tenancy is enabled by a new virtual data center embedding method that is equipped with network-aware VM placement exploiting the advanced but complex characteristics of diverse optical technologies.
A programmable all-optical data center network architecture with great scalability and flexibility is proposed and evaluated by a statistic data center traffic model to obtain the best utilization efficiency for optical packet/circuit switched network.
