UW’s High Speed Research Network (HSRN) and Science DMZ have been in operation since June 2010. The current HSRN connects the high-performance compute and storage clusters Hyak and lolo to each other, as well as providing a 10Gbs connection to campus. The Science DMZ feature of the HSRN enables high throughput data transfers to endpoints outside the UW networks. lolo acts as the campus Data Transfer Node (DTN) connecting at 10Gbps both inside and outside the campus security perimeter for optimal access by both on-campus researchers and their external collaborators.
