The Role of OSGi


Overview Residential Specification Release 4.3

2012: OSGi Residential Specification 4.3 published

Fulfills HGI SWEX Requirements e.g., • BBF TR069 Connector Service Specification • BBF TR157 Amendment 3 Software Module Guidelines • DMT Admin 2.0


Overview Residential Specification Release 6

2015: OSGi Residential Specification 6 published

• EnOcean Device Service Specification • USB Device Service Specification • Serial Device Service Specification • Network Interface Information Service Specification • Resource Monitoring Specification • Device Abstraction Layer Specification • Device Abstraction Layer Functions Specification


EnOcean Device Service Specification

•  API of an EnOcean Base Driver according to OSGi Device Access specification

•  Discovery and control of EnOcean devices as OSGi services •  Support for event handling •  OSGi services exported as EnOcean devices


USB Device Service Specification

•  Home Gateway use USB Dongles to support additional HAN technologies •  USB Device Services Spec. allows to get detailed information about connected

USB devices •  Realized as an OSGi USBInfoDevice service


Serial Device Service Specification

•  The Serial Device Service specification defines an API for establishing communication between an OSGi bundles and a serial device, such as a ZigBee coordinator or Z-Wave controller

•  No common abstraction from serial interface library in Java today •  Javax.comm is old •  RX/TX not carrier friendly


Network Interface Information Service Specification

•  Java today is not able to recognize and notify about changes in low level IP functions •  Network interface •  IP adresss / version •  MAC address


Resource Monitoring Specification

• Monitoring bundles resource usage • Granular activation

•  per Bundle •  per set of Bundles

• Five resource type are specified •  CPU, memory, disk storage, alive threads and in use sockets

• Resource types can be extended and query-able • Eventing mechanism


Resource Monitoring Specification – Typical Use Case


Device Abstraction Layer Specification

Basic Functions of a Device Abstraction API

• Discovery: Notification mechanism when adding or removing smart appliances

• Control and query: Set and retrieve state values of appliances

• Eventing: Notification mechanism upon change of state values

• Management: Inclusion/exclusion of appliances, key management, firmware upgrades etc.


Device Abstraction Layer...not

11/4/15



•  API applicable for all relevant device protocols ●  General device data model ●  Device operations •  Access control based on user and application permissions

•  Fine-grained security control •  Full flexibility of OSGi security model

•  A notification mechanism is needed for: •  Device state monitoring •  Device data model monitoring •  Device operations monitoring


Device Abstraction Layer Functions Specification

Functions flexibility Implementations of org.osgi.service.dal.Function

These functions can be • reused in a specific domain, • extended if required functionality is missing, or • replaced in a specific domain.

•  BooleanControl •  BooleanSensor •  MultiLevelControl •  MultiLevelSensor

•  Meter •  Alarm •  Keypad •  WakeUp


Conclusion •  OSGi REG delivered 2 specification releases for smart home •  Collaboration with other SDOs •  REG specification helped to drive adoption •  REG Specifications are also applicable to many other IoT verticals
