Portuguese Integration Model
THE ITSIBUS APPROACH
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.

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