Middleware constitutes a set of services which facilitate the
development of distributed applications in heterogeneous environments. The
primary objectives of middleware are to provide application portability,
distributed application component interoperability, and to facilitate
software component integration. Conceptually, the "middleware layer"
comprises a layer below the application and above the operating system
and network substrate. Common middleware platforms include CORBA, DCOM,
Java RMI, J2EE, MQSeries, MSMQ, and Web Services.

Research trends in middleware are manifest in algorithms, protocols,
and reusable software frameworks found in application domains such as
selective information dissemination, sensor networks, coordinated
robots, and peer-to-peer systems. These trends also cover emerging paradigms
for designing middleware platforms, including component technologies,
aspect orientation, and reflection which can provide reconfigurable
and adaptive systems. Future applications also include computing grids,
network centric operations, and intelligent transportation networks.
Middleware research improves distributed system scalability,
fault-tolerance, security, load-balancing, interoperability,
performance, and predictability.
