Miami, Florida, March 1, 2020 – Florida International University (FIU), Rede Nacional de Ensino e Pesquisa (RNP), Tertiary Education and Research Network of South Africa and South African National Research Network (TENET/SANReN), and Angola Cables are pleased to announce the activation of lightpaths initially provisioned at 100Gbps linking North America, South America, and Africa for research and education.

The Americas Africa Research and eduCation Lightpaths (AARCLight) project (NSF OAC-1638990) provided support for a grant to plan, design, and define a strategy for high-capacity research and education network connectivity between the U.S., Brazil, and West, Central and Southern Africa. The study indicated a high level of enthusiasm to engage in collaborative research among the U.S., Brazil and the African communities.

The AmLight-SACS project (NSF OCI-1937344), successfully established a 100G pathway using the South Atlantic Cable System (SACS) and West African Cable System (WACS), to extend the AmLight-ExP network from Fortaleza, Brazil to ZAOXI open exchange point in Cape Town, South Africa.

“AARCLight and AmLight-SACS have succeeded due to strong and consistent collaboration between the partners. Linking the U.S., Brazil and the nations of Africa to support robust research and education networking using a novel South Atlantic route is the culmination of 3 years of careful planning and execution. Enhancing the technological and social connections in many science disciplines including astronomy, biodiversity and genomics are anticipated to accelerate the rate of discovery while providing a diverse networking path for all collaborators”, said Heidi Morgan, Co-Principal Investigator and lead for the AmLight-SACS project.

AmLight-SACS leverages the network infrastructure in the southern hemisphere that is available to the R&E community. Using optical spectrum on Monet, AmLight-ExP links AMPATH R&E Exchange Point in Florida (USA) to South America eXchange (SAX) in Fortaleza (Brazil) at 200Gbps. SAX R&E Exchange Point is operated by RNP. Using optical spectrum on SACS, AmLight-ExP provisioned a 100G pathway from Fortaleza to Sangano (Angola). TENET/SANReN capacity on WACS was used to activate a 100G pathway between Sangano and ZAOXI R&E exchange point, in Cape Town. At ZAOXI, the Ubuntunet Alliance Network connects East Africa.

The SACS cable system between Fortaleza, Brazil, and Sangano, Angola, is the first modern east-west subsea cable in the South Atlantic. The activation of the AmLight-SACS path adds redundancy and resiliency to the global R&E network fabric by providing a transatlantic route across the South Atlantic, shortening paths from the Southern Hemisphere countries to Africa and Europe. The newly established connection provides a baseline for planning the next generation of collaborations involving major scientific instruments, safe in the understanding that there will be efficient, available, and unmediated connectivity and capacity between the continents.

To evaluate the connectivity, two 100G nodes at AMPATH were configured to generate packets that flowed from Miami, Florida to TENET/SANReN’s router at ZAOXI in Cape Town and back to Miami. The figure below shows the network utilization at 99Gbps for a period of one hour.

“The AmLight-SACS project exemplifies FIU’s Worlds Ahead mission as an international leader in Research & Education Networking to advance scholarship through high-quality teaching, state-of-the-art research and creative activity, and collaborative engagement with its local and global communities.  FIU is strengthening its ties and expanding its research around the world with our South American and African collaborators! All of this is possible because of the dedication this international project team has put into the first ever South Atlantic R&E network crossing between three continents” said Julio Ibarra, Principal Investigator of AmLight.

“TENET is honoured to have been part of this project and we are delighted that it is coming to fruition. Entire ranges of research problems will in the future depend for their resolution upon multi-partner, multi-continent collaborations such as this. We are especially pleased that African researchers stand to gain substantial benefits from the project” said Duncan Greaves, CEO of the Tertiary Education and Research Network of South Africa (TENET).

“We, at UbuntuNet Alliance, are excited to witness this major milestone of the AARCLight and AmLight-SACS Project which promises to resolve most of our major digital challenges facing our research and education communities in Africa. Cost, speed and access have been a major challenge in relation to satisfying the connectivity needs of our research and education communities and this project is well positioned to help solve these challenges in addition to opening wide opportunities for research collaboration and knowledge sharing between the three continents”, said Matthews Mtumbuka, CEO of UbuntuNet Alliance.

“In the 30 years since its launch as an academic network project, RNP has always supported international collaboration with similar initiatives around the world. The recent availability of the high capacity SACS link from Fortaleza to Angola has at last provided us with a direct physical connection to Africa which will complement our existing major links to the US and Europe. The new South America eXchange in Fortaleza will bring together RNP, RedClara and many other global research and education networks. These significantly lower latency routes to Africa will support much closer Americas engagement in education, research, development and cultural activities with African partners”, said Nelson Simões, CEO of the Brazilian Education and Research Network (RNP).

“The in-service of SACS between Brazil and Angola opens new opportunities for collaboration between research and education communities in Africa, Latin America and the US, with much less latencies than on previous routes. Moreover, it provides the opportunity to move on with the planned establishment of a Global Exchange Point in Lagos, using the SACS and WACS submarine cable systems”, said Boubakar Barry, CEO of West and Central African Research and Education Network (WACREN).
