Miami, FL December 19, 2017 - The SuperComputing17 (SC17) event was hosted in Denver, Colorado from November 14, 2017, to November 16, 2017. Over this period, network engineers from AmLight, Academic Network of São Paulo (ANSP), State University of São Paulo (UNESP) and the California Institute of Technology (Caltech) leveraged the AmLight-ExP [1] network infrastructure to transport large data-sets on 100Gbps links between São Paulo, Miami, and Denver.  Currently, AmLight-ExP has a total aggregated capacity of 240Gbps between South America and North America. In addition, two 100G circuits were installed between Miami and Denver provisioned by CenturyLink.

To generate network traffic for the demonstrations at SC17, several DTNs (data transfer nodes) running either nuttcp [2] or FDT [3] were leveraged in São Paulo (UNESP/ANSP), Miami (AMPATH) and Denver (Caltech and UNESP booths). Also, the Kytos SDN Platform [4]was utilized to provision Layer 2 paths between these DTNs for the data transfers using dedicated OpenFlow switches and AmLight SDN’s slicing capabilities. On November 16th, in the afternoon, several demonstrations were encouraged to generate as much network traffic as possible to fill-up SC17 links. At AmLight, a steady 370 Gbps total aggregated traffic was transported, which is illustrated in Figure 1.

“The conference was a great opportunity to showcase Kytos, an open-source SDN platform that has been developed by SPRACE with the support of Huawei. Our next step will be to deploy Kytos on the ESnet testbed in association with the AmLight engineers”, said Sergio Novaes, PI of SPRACE and scientific director of UNESP Center for Scientific Computing.

“We consider these achievements very important, and we are satisfied in participating in these successful demonstrations at SC17. Exercising and stressing intensive data transfers on multiple 100 Gbps WAN links between the United States and South America, especially, between Sao Paulo, Miami and Denver, give us confidence to support a service of intensive data transfers for our academic community, regionally or on globally distributed science programs”, said Eduardo Grizendi, Director of Engineering and Operation of RNP, the Brazilian Academic Network.

About AmLight ExP: AmLight Express and Protect (ExP) implements a hybrid network strategy that combines optical spectrum (Express) and leased capacity (Protect) that builds a reliable, leading-edge diverse network infrastructure for research and education. AmLight ExP operates high-performance network links connecting Latin America to the U.S., funded by the National Science Foundation (NSF award #ACI-1451018); With significant investments from the Academic Network of São Paulo (ANSP), and Rede Nacional de Ensino e Pesquisa (RNP) and the Association of Universities for Research in Astronomy (AURA), the total bandwidth provided by AmLight ExP between the U.S. and South America is expected to grow to more than 680 Gibabits per second in aggregate capacity between 2015 and 2020.
