Audio/Video Conferencing Systems need communication channels between their clients in order to transport RTP packets from one client to another. In this paper we investigate audio/video conferencing as a Web Service and the deployment of publish/subscribe systems in the context of audio/video conferencing systems. In this paper we use our research system NaradaBrokering, which supports both peer-to-peer and publish/subscribe paradigms, as a test bed to investigate these ideas. We also present results from our research system.

An Efficient Middleware Architecture Supporting Real-Time Distributed Object Programming, Erhan Saridoğan, Nadi̇a Erdoğan
Turkish Journal of Electrical Engineering and Computer Sciences
With the increasing demand for distributed real-time systems, the need for programming tools and execution platforms useful in development of such application systems is widely recognized. This paper presents CORD-RTS, an efficient middleware architecture that provides support for real-time distributed object programming. The communication infrastructure and various components of the middleware, which support several modes of interactions among distributed real-time objects, along with its real-time features and services, are discussed in detail.

Existing middleware is based on control-flow centric interaction models such as remote method invocations, poorly matching the structure of applications that process continuous information flows. Difficulties cultiesin building this kind of application on conventional platforms include flow-specific concurrency and timing requirements, necessitating explicit management of threads, synchronization, and timing by the application programmer. We propose Infopipes as a high-level abstraction for information flows, and we are developing a middleware framework that supports this abstraction. Infopipes transparently handle complexities associated with control flow and multi-threading. From high-level configuration descriptions the platform determines what parts of a pipeline require separate threads or …
