GÉANT Infoshare - Data Transfer Nodes: How Fast can your Data Travel?

Some research projects need to move huge amounts of data. Using a desktop computer and the regular network to do it may not be the right option to get the best performance. Setting up a DTN node is not always straightforward: there are different types of software, some parameters need to be tuned in the servers, distances reduce the performance in TCP...

The GN4-3 project, in its WP6 T2, has performed several tests using the GÉANT Testbed Service (GTS). The results are published in a matrix and the documentation and the scripts to set up nodes in a dockerised environment are available in the DTN wiki (https://wiki.geant.org/display/DTN).

This Infoshare will summarise the work around DTN done in the project, presenting the results, the matrix and the documentation. 

This Infoshare was held on December 9th, 2020 and was recorded. You can find the recording in the GÉANT channel: https://www.youtube.com/watch?v=-DSq_LCw36k

      Introduction to the DTN work in GÉANT 10m

      Introduction to the DTN work in GÉANT under WP6: from the survey among the NRENs and the DTN wiki to the GTS testbed, the OAV work and the virtualised nodes

      Tuning Parameters for DTN 20m

      How to tune parameters in Data Transfer Nodes to optimise the configuration and achieve the best results when transferring large scale science data.

      Dockerised DTN 20m

      DTN have been created in Docker for several operating systems, so that organisations willing to do their own performance tests can easily install nodes. In this presentation, we will see how to set up DTN tests in a virtualised environment using containers with Docker and the tests run on them.
