	abstract = {Quality of service guarantees for multimedia communication systems have been considered on several abstraction levels. In the multimedia networking field it is typical to identify the minimal QoS requirements of an application to save resources by guaranteeing its functionality. Many of these applications can operate in spite of an imperfect delivery of media data, while other applications such as distributed databases or distributed file systems consider perfect QoS necessary but accept delay. The basic problems of the latter is the consistency of their data, while the former require a consistent perception of the content. More generically, both QoS requirements can be interpreted as a problem of maintaining a consistent system state. Consequently we assume that many distributed applications, including most distributed multimedia applications, can fulfil their tasks in spite of imperfect consistency. Since the application requirements differ widely, the elements that make up \&ldquo;consistency\&rdquo; must be separated and classified. This paper introduces Consistency QoS and proposes a classification of elements that determine an application\&$\#$39;s consistency requirements. The low level QoS requirements that these separate parameters rely on are shown, and example parameter sets for application classes are given},

	abstract = {Internet video-on-demand (VoD) today streams videos directly from server to clients, because re-distribution is not established yet. Intranet solutions exist but are typically managed centrally. Caching may overcome these management needs, however existing web caching strategies are not applicable because they work in different conditions. We propose movie distribution by means of caching, and study the feasibility from the service providers{\textquoteright} point of view. We introduce the combination of our reliable multicast protocol LCRTP for caching hierarchies combined with our enhancement to the patching technique for bandwidth friendly True VoD, not depending on network resource guarantees.},

	abstract = {One major problem of using multimedia material in lecturing is the trade-off between actuality of the content and quality of the presentations. A frequent need for content refreshment exists, but high quality presentations can not be authored by the individual teacher alone at the required rate. Several past and current projects have had the goal of developing so-called learning archives, a variation of digital libraries. On demand, these deliver material with limited structure to students. For lecturing, these systems provide just as insufficient service as the unreliable WWW. Based on our system HyNoDe [HYN97] we address these issues in our distributed media server built of {\textquoteright}medianodes.{\textquoteright} We add content management that addresses teachers{\textquoteright} needs and provide guaranteed service for connected as well as disconnected operation of their presentation systems. Medianode aims at a scenario for non-real-time, shared creation and modification of presentations and presentation elements. It provides user authentication, administrative roles and authorization mechanisms. It requires an understanding of consistency, versioning and alternative content tailored to lecturing. To allow for predictable presentation quality, medianode provides application level QoS supporting alternative media and alternative presentations. Viable presentation tracks are dynamically generated based on user requests, user profiles and hardware profiles. For machines that are removed from the system according to a schedule, the systems guarantees availability of consistent, complete tracks of selected presentations at disconnect time. In this paper we present the scope of the medianode project and afterwards its architecture, following the realization steps.},
