…, During the course of the LSST and AmLight SC18 demonstrations, Dark Energy Camera (DECam) public data from the AURA site in Chile arrived via AmLight at both the KISTI and Caltech booths in Dallas, where it was mirrored and carried across SCinet, Starlight, KRLight and KREONet2 to DTNs at KISTI and KASI in Korea, as shown in the figure below. Using Caltech's Fast Data Transfer (FDT) application, throughputs of 58 Gbps were achieved across the 60 Gbps path from the telescope site to the KISTI booth, and a remarkable 99.7 Gbps on the 100 Gbps path between Dallas and Daejeon.…
