The aim of the ANA-100G project is to try out technology, operations and organization for inter-continental R&E networking by bringing the interconnection between continents on par with the intra-region transmission speeds of 100 Gbit/s, and by doing so with jointly owned and operated resources. As such the ANA-100G project functions as a path finder for the Global Network Architecture.

It was clear from the outset of the ANA-100G project in early 2012 that the market was not ready for 100 Gbit/s service delivery across the North Atlantic ocean (or any other ocean). During the summer of 2012 the ANA-100G project worked with many of the active carriers across the North Atlantic to set up a pilot infrastructure to learn about the implementation and use of a 100G clear channel pipe on this path. The main goal of the ANA-100G pilot phase was to gain knowledge and experience in setting up and running a 100 Gbit/s data path between two Open Lightpath Exchanges (OLEs), for an extended period of time, i.e. 12-18 months. At the Internet2 Conference in April 2013, the intention to pilot 100G across the North Atlantic was made announced.

What was envisioned, happened. The ANA-100G Pilot was run as a private-public partnership of the six R&E Networks (Internet2, NORDUnet, ESnet, SURFnet, CANARIE and DANTE/GEANT) and two industry partners (Ciena and Tata). In this collaboration, Ciena supplied their brand new ultra long haul (ULH) 100G submarine transponders. Tata supplied spectrum on their Tata Global Network – Atlantic South (TGN-A South) cable system over which the R&E Network owned transponders were run. From day 1 of the pilot OLEs were used as landing points for the trans-oceanic 100G. The link was up on the day before the start of the TERENA Networking Conference 2013 (TNC2013) in Maastricht, The Netherlands, and demonstrated the successful delivery of the world's first intercontinental clear channel 100G at TNC2013.

In the spring of 2014, the ANA-100G Collaboration decided to enter a new phase for the ANA-100G project: A resilient 100 Gbit/s production facility consisting of a ring of 100 Gbit/s links between four Open Lightpath Exchanges. This infrastructure is called ANA-200G, and is being put into service during November 2014. The topology of ANA-200G has no single point of failure:
