NC BioGrid Network Infrastructure
The NC BioGrid is the first high performance computing project designed to exploit the world-class North Carolina Research and Education Network (NCREN), which provides Internet connectivity to the state's university community. Its latest iteration, NCREN3, will provide increased bandwidth, reliability and resiliency through counter-rotating OC-48, OC-12 and OC-3 rings running respectively at speeds of 2.488-Gbps, 622-Mbps and 155-Mbps. The NCREN3 project web page provides additional architecture information. The following map shows the topology of the NCREN3 network as it will be when it is fully completed (click on the image for a larger view).
At the present time, the NC BioGrid Testbed takes advantage of the OC-48 core of NCREN, which interconnects the R-1 Triangle universities and MCNC. The NC BioGrid servers are (or will be shortly in some cases) connected to the NCREN network via Gigabit Ethernet. This provides the grid with very high bandwith and low latency between sites. The following diagram shows how the Phase 1 Testbed sites are interconnected (click on the image for a larger view).
