The EU DG Connect and the US National Science foundation established a joint EU-US committee bring together researchers from both sides of the Atlantic. The committee was asked to discuss the joint development of research-focused networking testbeds and identify joint research opportunities. The committee was organized as two subcommittees, focusing on two broad areas: “Next Generation Internet (NGI)” and “Advanced Wireless Platforms”. The committee met for a workshop at the DG CONNECT premises in Brussels on June 26-27, 2017. The workshop was collocated with the “Net Futures Conference 2017”, which included an “EU- US session on next generation internet” on June 28.
