Object Bus: System Support for Hot-Pluggable Network Objects

Keywords:
  Information Bus, Group Communication, CORBA, OMG Event Service

*** This presentation will be in English ***

Abstract:

The OMG CORBA standard is becoming popular for building
mission critical distributed systems. However, today's implementations
of CORBA do not meet the stringent demands that mission critical 
applications impose on reliability and flexibility.

Internet based electronic commerce will require that business
information
systems be available on a 24 per 365 basis. Innovative businesses will
thus have to extend and upgrade their running software infrastructure to
seize new business opportunities, while keeping their current customers 
happy.

This talk explains the Object Bus communication paradigm that provides
a decoupling of the sender of information from the receivers of the
information. This is achieved through an event channel infrastructure
that is typically implemented atop of a multicast subsystem.

I will also explain why I believe that this paradigm is
best suited to the development of flexible distributed systems
that are both highly available and extensible at run-time. 

Finally, I will briefly describe how the Object Bus paradigm is provided 
by the TIBCO Information Bus, by IONA's OrbixTalk, and by the Olsen
CyberBus.
