Real-time communication enabler for Web 2.0 applications

In face of the markets growing around community-centric services and applications telecommunication companies adapt their products to new technology landscapes. We investigate the possibilities of network operators to contribute to the quality of a service that enables real-time user interactions for hypertext user interfaces. The central quality criterion considered here is the latency in browser-based user-to-user interactions. We introduce the context of our work, the challenges we are facing and the conclusions we draw. Taking this as foundation we describe a bipartite architecture that combines an extension of the hypertext protocol stack with application-controlled network quality of service.
