Multi-domain TF services
European-wide TF services require the development of an architecture to support the maintenance of the TF infrastructure and the exchange of measurement data in a multi-domain environment.
| Frontend: - user authorisation and resource access allocation (scheduling of measurements, access to measurement data, reporting and receipt of tickets)
- access to real-time measurement data and the status of a given connection
- resource scheduling (booking of measurement sessions)
Global TF service management: - gathering and processing of measurement data
- aggregation of measurement data from local databases for selected international connections
- update of the status of connections in the multi-domain network
- the main source of information for the frontend
|
Gateway (GW): - connection point between two different TF domains
- requires measuring equipment that continuously records the relative differences of the signals transmitted in adjacent domains
- recorded data should be streamed to the global database in real time
| Local data base / management: - Function similar to Global TF Service Management but limited to one domain / subnetwork only
