We investigate the problem of optimal routing and resource allocation in the context of performance-dependent costs. In this context each network element can offer several QoS guarantees, each associated with a different cost. This is a natural extension to the commonly used hi-criteria model, where each link is associated with a single delay and a single cost. This framework is simple yet strong enough to model many practical interesting networking problems. An important problems in this framework is finding a good path for a connection that minimizes the cost whilst retaining the end-to-end delay requirement. Once such a path (or a tree in the multicast case) is found, one needs to partition the end-to-end QoS requirements among the links of the path (tree). We consider the case of general integer cost functions (where delays and cost are integers). As the related problem is NP complete, we concentrate on finding efficient /spl epsi/-approximation solutions. We improve on recent previous results, both in terms of generality as well as in terms of complexity of the solution. In particular, we present novel approximation techniques that yield the best known complexity for the unicast QoS routing problem, and the first approximation algorithm for the QoS partition problem on trees, both for the centralized and distributed cases.","PeriodicalId":416650,"journal":{"name":"2000 Eighth International Workshop on Quality of Service.

However, both techniques also have limitations, particularly when dealing with high-bandwidth, dynamic flows: fixed-capability reservations tend to be wasteful of resources and hinder graceful degradation in the face of congestion, while adaptive techniques fail when congestion becomes excessive. We propose an approach to quality of service (QoS) that overcomes these difficulties by combining features of reservations and adaptation. In this approach, a combination of online control interfaces for resource management, a sensor permitting online monitoring, and decision procedures embedded in resources enable a rich variety of dynamic feedback interactions between applications and resources. We describe a QoS architecture, GARA, that has been extended to support these mechanisms, and use three examples of application-level adaptive strategies to show how this framework can permit applications to adapt both their resource requests and behavior in response to online sensor information.","PeriodicalId":416650,"journal":{"name":"2000 Eighth International Workshop on Quality of Service.

To solve this challenge, we need a unified QoS framework, which allows flexibility and reconfigurability. In this paper, we present a reconfigurable component-based QoS framework, called 2K/sup Q/, which solves the challenge by partitioning the end-to-end QoS setup process into distributed QoS compilation and runtime QoS instantiation phases for different types of applications. Entities, services and protocols of this framework, such as application-to-component translator and component-to-resources translators, achieve the distributed QoS compilation and prepare all necessary QoS structures for the end-to-end QoS setup. Other capabilities of this framework, such as a reconfigurable middleware and functional adaptation, achieve the runtime instantiation of the end-to-end QoS setup. We have implemented the first prototype of this framework and the results show a feasible overhead of the runtime service instantiation and reconfiguration for different applications and their QoS requirements.","PeriodicalId":416650,"journal":{"name":"2000 Eighth International Workshop on Quality of Service.
