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. Slide 19 Architecture Slide 20 HA TO-BE ARCHITECTURE Strategic implications Slide 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. Slide 22 Legacy Integration Smart endpoints provide an abstraction layer for Encapsulation: Java, C++, DCOM, CORBA Adapters (e.g. JCA J2EE Connector Architecture) Slide 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
