The itsibus approach

• Portuguese Integration Model

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.

• Strategic implications

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 RSUs 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
