2 What is the OSGi Technology? OSGi is a Standardized Software Execution Environment Component based module system defined in Java Open Standard defined by the OSGi Alliance Service oriented & remotely managed (OMA & TR-69) Works like an operating system for small applications called Bundles Ideal for a home gateway, IoT gateway, or similar equipment Home Control Energy Mgmt Media Application Components M O ST C A N P r e f s H TT P C on f L o g A ge n t Administrator OSGi Framework JVM / OS / HW Mgmt System Framework + std OSGi components!2 COPYRIGHT OSGi Alliance.

7 Real world example of a bus fleet system based on OSGi An example of a bus fleet system based on Makewave s OSGi Technology Knopflerfish OSGi edge device stack Ubicore - a remote management system for edge devices ~5 000 buses, edge bus having ~5 edge devices running OSGi. 7

8 System Architecture - bus fleet All buses are equipped with one or more OSGi based on-board computers / devices. Each OSGi platform has a management agent which connects it to Ubicore Bus OSGi on-board Operator Bus OSGi on-board - Ticket Bundles Bundles Bundles Ticket Server OSGi on-board - Ticket Bundles Bundles Bundles Ubicore OSGi on-board - Driver Console Bundles Bundles Bundles Back-end Driver Server Vehicle network Bus OSGi Gateways 8

9 System Architecture - bus fleet Every bus has one or more on-board computers that has an embedded OSGi platform (Knopflerfish) The on-board computers are connected to the in-vehicle network (FMS) The on-board computers are connected to each other (in-vehicle IP) Every on-board computer has an OSGi management agent. The agent is responsible for the connection to Ubicore and performs mgmt tasks decided by Ubicore. All business logic is implemented as OSGi bundles. The business logic bundles are all managed via Ubicore. The business logic bundles sends / receives data directly to/from its corresponding back-end server. I.e. the IP traffic is not routed via Ubicore The Ubicore server is part of the complete back-end server infrastructure. It is integrated with other parts via a REST API. 9

10 OSGi is an embedded integration platform My App Bundle Temp Sens Temp Meter OSGi platform WebCam Web Cam Service Temp Temp Controller OSGi provides a sandbox in which bundles exist and exchange data. An API layer is provided to the Application Logic The Service is logically using a device, but physically abstracted Devices Java Virtual Machine (JVM) Operating System Local network 10

11 Inside one vehicle Back-end / Cloud Communication gateway OSGi on-board Knopflerfish Ubicore Tracking Server Validation Server Bundle Cache OSGi on-board Knopflerfish OSGi on-board Knopflerfish FMS OSGi on-board Knopflerfish Driver Console Validators 11

12 Benefits with an OSGi solution Clear separation between business logic (implemented as OSGi bundles) and lower lever parts device code (C/ C++). Uniform architecture - exactly the same business logic bundles can be used regardless of on-board computer architecture (ARM, X86). No need to recompile, or support different versions. Remotely Managed and Flexible - it is very easy to add, remove or update functionality in the business logic layer over time. 12
