  5. GISFI-ETSI Interfaces CASE -1 Direct device to device Connectivity and interfaces are not considered in GISFI current arch

  6. TIA Reference Points A1: AAA - the application server. A2: AAA - the intermediate node. A3: AAA - the smart device controller. A4: AAA - the smart device. B1: application -intermediate node. B3: intermediate node -smart device controller. B5: application server -smart device. B6: intermediate node - intermediate node B7: smart device -smart device X: device - smart device controller. This reference point is outside the scope of this document. GISFI # 07, Dec 19-22, 2011, New Delhi 6

  12. Conclusion: TCS Proposed IoT Architecture in GISFI • I1 Signifies a family of interfaces including the 3rd party network accessibility. • Device to device connectivity and interfaces are not considered. • I2 Signifies the interfaces for application middleware/ application to devices directly, as well as application middleware to access gateway. Devices are considered addressable. • Internet is considered as Backbone network. • Chaining among application middleware nodes as well as access gateways are considered. • Nointerfaces are defined for this. No use case is mapped yet. Chaining of application middleware may suitable for distributed computing. • I3 (APIs) Interface exposed from application middleware to Application does not exist in ETSI & TIA GISFI # 07, Dec 19-22, 2011, New Delhi 12
