Instant-X - A generic platform for multimedia communication services
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.
