About the GREN Global Map Working Group

The GREN Global Map working group of volunteers from the R&E Networking community, working on data formats and applications facilitating collaborative, interactive network maps.

The initial criteria for the success of the delivered visualisation product are:

  1. A dynamic/interactive map (zoomable with selectable layers and sections), which also supports printed versions;
  2. The ability to show intra- and inter-NREN nodes and connections, including some meta information (e.g. link speed);
  3. The ability to show connected institutions and major science infrastructure and instruments;
  4. A model where data is maintained by individual (N)REN operators and collected automatically, in a common format, in order to reduce update overhead and keep the map continuously up to date; and
  5. Achieving a critical mass of participation.

Group Chairs

Existing Maps

This is not an exhaustive list.  It is recognised that most networks have a static or dynamic map.  We have identified the following examples as a cross-section in order to gather initial requirements for our efforts:
