Future hypermedia retrieval systems and their impact on transfer systems
Among the most popular distributed applications in today's networks are Hypermedia Retrieval Systems. Due to their rising popularity as well as performance limitations imposed by the underlying communication system the well known ‘World Wide Web’ is turning a ‘World Wide Wait’: Response times increase and at peak traffic times many sites are virtually unreachable. On the other hand emerging network technologies like ATM offer a guaranteed Quality of Service (QoS). Future Hypermedia Retrieval Systems will have to be able to reserve bandwidth and request certain timing constraints depending on document media type. Due to the properties of these new media, additional temporal requirements are not only imposed on the presentation (i.e. synchronisation of audio, video and textual information) but also on the transmission of these media streams. There is a desperate need for a uniform QoS architecture and interface for mapping presentation quality to communications requirements to efficiently support the requirements of future distributed multimedia systems and to make optimal use of the QoS capabilities of new networking technologies.
