The NEPHELE data center interconnection network relies on hybrid electro-optical top-of-rack switches to interconnect servers over multi-wavelength optical rings. The bandwidth of the rings is shared, and an efficient utilization of the infrastructure calls for coordination in the time, space, and wavelength domains. To this end, we present offline and incremental dynamic resource assignment algorithms...
Energy consumption and the associated costs constitute a crucial issue concerning the design and operation of data networks and data centers. Energy-awareness is required in all levels, ranging from physical layer to algorithms, protocols and applications. Architecture-wise, a promising solution for tackling the increasing energy requirements is the deployment of optics at both long and shorter distances,...
The NEPHELE datacenter network is divided into pods/clusters of racks and relies on hybrid electro-optical top-of rack switches that access an all-optical network consisting of WDM rings. To enable dynamic and efficient sharing of the optical resources and a collision-free network operation, the NEPHELE network is designed to operate in a slotted manner with a software-defined-network (SDN) based...
We demonstrate the Optical Board Simulator platform for optical PCB layout design and performance evaluation. Performance of two optical Blades is compared to CRAY-XK7 Blade for the FFTW benchmark, revealing significant throughput and latency improvements.
In this paper, a new service oriented networking paradigm is presented, where network nodes (peers) are self- organized into individual service entities. The key idea relies on the overlay approach, where there exists a virtual service plane, fragmented into self-organized and self-managed entities called islands of service transparency. The islands are formed in an upstream, ad-hoc mode from the...
