With eduroam Managed IdP, there is a service which takes all RADIUS hassle off of Identity Providers. There is no equivalent for eduroam SPs. I.e. a future eduroam SP either needs to set up a local RADIUS server and connect it to the NRO, or (if the NRO supports it) connect the Wireless Controller directly to an NRO server - losing all advanced features such as VLAN assignment. For small hotspots, there is a possible additional complication if the hotspot has a dynamic IP address, which makes the interconnection via RADIUS' shared secrets infeasible. Right now, such potential hotspots are not serviceable by eduroam infrastructure.

The goal of this activity is to create a self-service web portal where any prospect SP can register his hotspot (requiring sign-off by the NRO; comparable to eduroam Managed IdP) - regardless whether he has a static IP address, a dynamic one, or doesn't even know what an IP address is in the first place. The new hotspot's RADIUS connectivity is tested in real-time (e.g. using a credential from eduroam Managed IdP, a good complement to this service) and the new SP is instantly connected to the eduroam infrastructure. Where the NRO admin confirms that a particular hotspot maps to a specific realm or Managed IdP instance, the SP can even get VLAN ID assignments for his own users (that part of the use case is possibly a bit weak as an SP who does not know about setting up a RADIUS server likely also doesn't know about VLANs to begin with).

For the technicalities of the uplink itself, there should be support for multiple attachment anchors (=RADIUS servers behind the web interface) because geographical proximity to the hotspot is important for performance reasons.

The remaining complexity for the SP which this service will not take away is: phyiscal installation of APs, controllers, and the configuration of those so that they are providing proper local eduroam.

To ensure service quality on such "no clue" SPs, it could be made mandatory to install a probe at the site so eduroam Operations can monitor the hotspot quality.

VM for web interface, VMs for RADIUS attachment anchors, a clever idea how to handle registering hotspots with dynamic or unknown IPs

There were a multitude of reasons why the GÉANT community couldn't run the infrastructure for WIFI4EU.

Sufficient issues were exposed by managing this as a single centrailsed infrastructure (partially addressed by "get eduroam", "eduroam DEEP Learning", "eduroam SP-as-a-Service"). By identifying all the scaling blocks to existing eduroam services we'd be able to offer advice, guidance and technology push into govroam, WIFI4EU and eduroam services to support the existing infrastructure and development in new territories.

Great chance to accelerate the deployment of secure public Wi-Fi systems in the world and to inter-connect them. Related to my proposal of inter-roaming, but a separate work item dedicated to WiFi4EU is still preferred. (Hideaki Goto, NII)
