Based on OFDM, a novel architecture named flexible grid optical network has been proposed, and becomes a promising technology in data center interconnections.
In response to the need for high bandwidth and power efficient data center interconnection networks, different interconnects have been proposed based on the optical technology used: micro-electromechanical system (MEMS), optical cross connects (OXCs), arrayed waveguide grating routers (AWGRs) and semiconductor optical amplifier (SOAs).
We create applications and analysis engines for media, and we are driven by social and data-driven interconnections.
Topologies for data center interconnection networks have been proposed in the literature through various graph classes and operations.
As a result, the application of optics has been widely investigated for arithmetic and logical processing, image processing, neural networks, data storage, interconnection networks, and ultrafast system bus.
Motivated by the good performances in practice of these new routing schemes, we propose the first general study of the hyperbolicity of data center interconnection networks.
In this paper, we present a novel cross stratum resilience (CSR) architecture for OpenFlow-enabled data center interconnection with Flexi-Grid optical networks.
To provide such high-capacity network channels, data center interconnection is typically based on Flexi-Grid optical networks that ensure the performance guarantee of low delay, high availability and robustness at a low cost.
For the first time, the flexible grid all optical networks with Tbps end-to-end tunable transport and switch system have been online demonstrated for data center interconnection, which are controlled by OpenDayLight (ODL) based controller.
Our findings are disappointingly negative: we prove that the hyperbolicity of most data center interconnection topologies scales linearly with their diameter, that is the worst-case possible for hyperbolicity.
