Quality of Service (QoS) management becomes more and more important, especially in networks where many applications are competing for a limited number of resources. As these applications become more complex (consider e.g. multiparty multimedia applications), the number of options for QoS management increases, leading to more complex decision processes. In this paper, we propose an approach for ...

Is it possible, and to what extent feasible, for link schedulers and buuer managers in multimedia networks with propagation delays to eeectively relieve congestion by means of feedback signalling? We show that a proactive, cooperative control algorithm for distributed resource scheduling and buuer management of multime-dia networks based on traac predictions of correlated input traac streams in...

A prototype system designed for enhancing the cooperative research of groups and individuals in research institutes is provided. The main implementing techniques are introduced as well.

In this paper, we propose a receiver-cooperative bandwidth management method for layered multicast streams, considering not only bandwidth requirements but also receivers’ preference. In our method, we assume that each receiver has a preference value for each layer of streams. When a receiver requests an additional layer and required bandwidth is not available on links, it can let other receive...

In this demonstration we introduce Gelee, our online platform for the hosted specification and cooperative execution of lifecycles of artifacts of any kind. With Gelee we aim at filling two lacks we identify in current cooperative software systems when it comes to unstructured, artifact-based works (e.g., the writing of a project deliverable): the lack of state and the complete lack of automate...

Network services must self-adapt dynamically in order to accommodate available resources, system errors, and changing requirements. This need for self-reliance will increase with the growing flexibility and heterogeneity that characterizes such network technologies as sensor (ad hoc) networking, grid computing, and pervasive computing. The downside of traditional distributed network management ...

The possibility to enable cooperative concept in urban traffic systems is challenging because of large amount of traffic data that must be collected, processed and distributed to end users. The main objective is to establish communication between three main subsystems of traffic system: driver, vehicle and infrastructure so that they can cooperate in real time traffic environment. This paper de...
