THE ITSIBUS APPROACHPortuguese Integration Model

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 ARCHITECTUREStrategic implications

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
