This Wiki page aims to provide a concise review of “state-of-the-art” in the use of DTN infrastructures by NRENs, primarily those in Europe, but activities by R&E networks outside Europe are also referenced. The review includes experiments, testbeds, architectural components (including transfer software and user interfaces), lessons learnt, and a gap analysis.

We conducted a survey to investigate how European NRENs support their user communities in making optimal use of their networks for large scale data transfers, including the use of Data Transfer Nodes (DTNs). Results are available at: GÉANT NREN Survey
