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
