We show the first hitless 100Gbit/s real-time bandwidth-variable transmitter integrated with restful server and OTN switching matrix. Between 10.7Gbit/s and 107Gbit/s, the transmitter reconfigures in less than 450μs without packet loss and additional penalty.
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.
The operation of multi-domain and multi-vendor EONs can be achieved by interoperable Sliceable Bandwidth Variable Transponders, a GMPLS / BGP-LS-based control plane and a planning tool. This paper reports the first full demonstration and validation this end-to-end architecture.
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.
We show an all-optical ultra-low latency server-to-remote memory/storage data center interconnection, exploiting programmable, flexible, bi-directional and data-rate transparent 4×16 Spectrum Selective Switches and supporting elastic WDM/TDM services using fast nanosecond tunable lasers.
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.
We successfully demonstrate a flat-structured DCN powered by large-port-count fibre-switch-based OCS, PLZT-switch enabled TDM and MEFs supported SDM. The inter-DCN ToR-to-ToR direct optical connections are setup through metro/core networks using all-optical SDM/WDM converters.
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.
