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 infrastructur

Adding Support for Delay Tolerance to IPv6 Networks

AbstractAs we continue to connect ever lower power and more power constrained devices to the Internet of Things the problem of main- taining constant end to end connectivity becomes harder. Accepting that continuous end to end connectivity cannot be maintained, we are forced to seek solutions to allow good operating function. Delay Tolerant Networking, an evolution of existing store and forward systems is a candidate for resolving this issue, however, current implementations are not ideal for use in constrained Inter- net of Things environments. We propose a solution to this by integrating the capabilities of Delay Tolerant Networking into the IP layer, in such a way as to maintain compatibility with existing and future systems and minimising additional overhead. This has been achieved by developing a new IPv6 Hop by Hop option header which contains the information required for messages to be delayed. This solution is then demonstrated to be implementable within the limitations of current Internet of Things hardware

Memetic: from meeting memory to virtual ethnography & distributed video analysis

The JISC-funded Memetic2 project was designed as knowledge management and project memory support for teams meeting via the Access Grid environment (Buckingham Shum et al, 2006). This paper describes how these capabilities also enable it to serve as a novel distributed video analysis tool to support interaction analysis. Memetic technologies can be used to record, annotate and discuss sessions recorded within a flexible, visual hypermedia environment called Compendium. We propose that beyond the use originally conceived, the Memetic toolset could find wide ranging applications within social science for virtual ethnography and data analysis
