The University of Wyoming (UW) Science Network (UWSN) is the campus implementation of the science DMZ principle. The guiding principle behind UWSN is that the campus research community should be able to optimize their access to other research entities, data stores and computing resources specific to the needs of their individual projects. To accomplish this they must overcome barriers of bandwidth constraint, high-latency, or the restrictions of an active security perimeter and be provisioned with the most efficient network possible. A "Science DMZ" (external link) ("science demilitarized zone") is a portion of a larger network that has been configured and optimized for high-volume bulk data transfer, remote experiment control, and data visualization for high-performance science applications.

A science DMZ should be scalable, incrementally deployable, and adaptable to new technologies. In order to achieve the maximum speed and throughput possible, the UW implementation of the science DMZ model avoids the regular campus exit architecture, and is neither restricted nor protected by the campus firewalls.

Globus Team Testing of the UWSN

The UWSN was recently offered to the Globus team as a high speed data transfer endpoint for people to use to tune their installations. We discovered in our testing that none of the current Globus test endpoints had better than a 1 Gbps connection. We have offered to make available our Globus servers (with their 40 Gbps network pipes) as test endpoints which will help us, as well as others, fully exploit the high speed network connections. To date we have sustained 10 Gbps transfers in Globus and 25 Gbps transfers inside the UW data center. We have identified several bottlenecks with the current configuration. We will keep working on tuning this up to the full network bandwidth.

Cheers,
