Lookup services Clause Samples
Lookup services. A federation gateway look-up/tracker service must be available that allows a gateway to register and discover their neighbours. Such as service should record, among other things: • gateway reachability information (public IP address if available, ports on which services are mapped, rendezvous server if behind a NAT etc.); • physical location (to exploit services requiring radio reachability); • gateway capabilities (available services, available storage space, available bandwidth, users information etc.); • broadcast beacon-based identification for FIGARO gateways in the wireless neighbourhood.
Lookup services. The Lookup services interface can be remotely accessed from the gateway services. The functions that need to be exposed by the Lookup Services are essentially registration and lookup of neighbour gateways, summarized in the following high-level interface: • Gateway registration: allows a gateway to register itself with its location so as to be reachable from other gateways • Gateway lookup: allows to search gateways with specified characteristics e.g. proximity of a given location Typical Authentication, Authorization, and Accounting (AAA) functionality is expected for secure and accountable operation of the gateway federation. FIGARO do not impose any specific requirements on standard AAA services.
