Instant-X - A generic platform for multimedia communication services
OSGI - One of the Top Five Java Technologies to Learn in 2008
Project Description
Currently, applications for spantaneous and direct communication via the
Internet (such as instant messaging, instant streaming, voice-over-IP,
video-on-demand) have to implement the transmission, signaling, reservation and
the coordination on their own. Only basic protocols and support for encoding
and decoding are typically provided by the operating system. This leads to
inflexible software systems and incompatibilities because for instance novel
signaling protocols can hardly be integrated later.
 |
The aim of this project is the development of a middleware platform supporting
such applications by providing common protocol implementations. This increases
the flexibility and improves interoperability. Generic applications can, for
instance, for instant messaging, work with different protocols. The most
important requirement for this is the development of an API, which provides
abstract functions for signaling, negotiation, reservation, and data
transmission, without forcing that the concrete implementation has to be known.
Furthermore, the middleware functionality as well as the applications are
packed in dynamically loadable, updatable and extendable components. |
The parts of the project are validated by the development of several example
applications: a generic instant messenger, a video softphone as well as an
application browser, which allows the dynamic installation of new application
components at runtime.
