  17. Portuguese Integration Model The itsibus approach

  18. ITSIBus and SOA • Uses an Enterprise Service Bus (ESB) for integration middleware – in production since 2004. • Everything as a service • A functional component in ITSIBus is always a service • A service implements an open interface and generates subscribe-able events (by other services) • • Services run on Systems • Systems are service execution containers offering core services for common functions (e.g. security, management, monitoring) • • Services are available from multiple technologies • Being standard, services can be called from different technologies.

  19. Architecture

  20. Strategic implications HA To-Be architecture

  21. Intelligent Highways Infrastructure • Adopts Portuguese ESB model as an exemplar. • Federated ESB approach fits with OGD and EU developments – Defra (INSPIRE), Police (ISS4PS), Customs & Excise (XSIZE), etc.

  22. Legacy Integration • Smart endpoints provide an abstraction layer for “Encapsulation”: • Java, C++, DCOM, CORBA • Adapters (e.g. JCA – J2EE Connector Architecture)

  23. Conclusions • The Intelligent Highways Infrastructure requires future-proofed ESB Endpoints which need to include RSU’s that can accommodate: • Legacy transponders • 3GRSE-based Data Hubs • CVHS-based Roadside Gateways • These need to be based on: • Industry standards (e.g. UTMC/Datex II) • Ruggedised PC hardware • IPv6 network interfaces/addressing
