This paper offers a high-level retrospective
overview of the GOPI middleware platform which is the
outcome of a three-year project aimed at the development
of generic, configurable and extensible middleware. GOPI
has a clearly defined modular structure, is widely extensible
with plug-ins at all levels of the architecture, and natively
supports stream interactions as well as standard operation
invocation. It offers a generic framework for quality of service (QoS) specification and management, and supports a
high-level, multimedia-oriented programming environment
that is backwardly compatible with the OMG’s CORBA. At
its lower levels it supports QoS-driven resource management
and features an optimised IIOP stack. Despite its enhanced
functionality, GOPI’s IIOP performance equals or exceeds
that of state-of-the-art CORBA platforms.
