Home Control

• 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


The OSGi Alliance• The OSGi Alliance is worldwide, non-profit consortium • Creates and controls the OSGi Specifications • The OSGi Technology is uses in a wide range of open

source projects and commercial products for IoT, cloud and enterprise markets.

• OSGi Alliance members include:

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.

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

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.

Operating System

• 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

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.
