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.

Architecture

Strategic implications 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
