Visualising roaming within eduroam

The eduroam federated access service is a valuable tool for supporting collaboration and resource sharing worldwide, with its primary purpose being to facilitate seamless wireless roaming between users at participating institutions. There are over 100 participating sites in the UK that have joined the UK instance of eduroam known as the JANET Roaming Service (JRS). However, while the JRS is gaining traction in deployment, there is a lack of visualisation tools for users, site administrators or JANET managers to understand and see the general roaming patterns. This paper will describe the implementation of and demonstrate a number of three-dimensional, interactive visual representations of eduroam log data from the JRS. These visualisations give a comprehensive overview of JRS roaming in the UK that, for example, communicate the ‘value’ of the service in a single image [Figure 1], give overviews at the institutional level [Figure 2] and provide diagnostic information to the service operators [Figure 3]. The software is open source and is being developed with a view to it being offered for adoption by other NRENS and the international core eduroam infrastructure
