Session Abstract

In an effort to eliminate “Big Data” flow problems, LSU and the LONI Network are in the midst of implementing a project that will connect specific research resources, people and machine, across the state of Louisiana’s public universities to a common cyberinfrastructure known as a Science DMZ.

The NSF funded projects, “CC-NIE Network Infrastructure: CADIS -- Cyberinfrastructure Advancing Data-Interactive Sciences” and CC-NIE Network Infrastructure: BDoSDN -- Bridging, Transferring and Analyzing Big Data over Campus-Wide Software Defined Networks” coupled with funding from the Louisiana Board of Regents will build upon a NSF EPSCoR completed project, “Louisiana’s Cyber Connectivity via LONI” to provide a network infrastructure which connects LSU’s HPC resources and LONI’s HPC resources to 5 research centers and 6 colleges on the campus of LSU. The Science DMZ will provide connectivity to the resources in 10 and 40-gigabit speeds with connectivity back to the LONI Network core and Internet2’s AL2S at 100-gigabit.

Our vision is to provide straightforward paths for upgrading laboratories and offices to higher bandwidth connectivity as the capabilities of LONI and I2 expand, create opportunities for diverse research community to more effectively interact with huge data sets that are generated on local (LSU), regional (LONI), and national (XSEDE) HPC resources, enabling new scientific and engineering discoveries, establish a Software Defined Network parallel model to our traditional campus approach, tune our network delivery for Big Data transmission with the assistance of perfSONAR, and develop Bid Data frameworks using Hadoop and MPI technologies over HPC resources.

The AARNet network has been making some great leaps forward over the past twelve months, in order to better support our institutions and their collaborations within Australia and overseas.

The AARNet4 upgrade is bringing 100Gbps capacities and new VPN capabilities both nationally and internationally. The links carrying Australia’s research and education traffic to the USA and beyond via the Southern Cross Cable Network are now at 40Gbps, supporting the ever-increasing “Big Data” flows generated by projects such as the Large Hadron Collider and the upcoming Square Kilometre Array, as well as daily by Australia’s numerous supercomputing facilities.

AARNet is also supporting the RDSI project (“Research Data Storage Initiative”), and its sister project NeCTAR (“National eResearch Collaboration Tools and Resources”). Nodes of cloud storage and compute power are being deployed across Australia to support nationally significant research, interconnected across the AARNet network. The Science DMZ architecture is integral to this, bringing immediate improvements to the ability of researchers to share their data.

This presentation will provide an insight into architectural and other challenges specific to research and education networking in Australia and current progress on all these fronts, highlighting the range of research and big science applications that these will facilitate.
