We propose a minimum cost method for traffic shaping and policing in the context of quality-of-service (QoS) based networks. Given the user's desired QoS and the network's resource availability, our procedure determines the least-cost parameters for a traffic shaper or policer which still guarantees access to the network whilst satisfying the QoS constraints. We illustrate our scheme using on-o...

| We propose a minimum cost method for trafc shaping in the context of QoS-based networks. Given the user's desired QoS and the network's resource availability, our procedure determines the least-cost parameters for a tra c shaper which still guarantees access to the network whilst satisfying the QoS constraints.

Quality of Service (QoS) requires standardization to achieve some consistency in terminology, models and mechanisms to operate successfully in an open distributed environment. This paper embraces this standardization effort and addresses the QoS issue from an ODP perspective. The objective of this paper is to relate the multimedia QoS concepts found in the literature and ISO-QoS framework to th...

Determining the QoS (quality of service) of composite Web services is of crucial importance for both service providers and consumers. However, service descriptions of constituent services are often heterogeneous which makes the aggregation of multiple single-service QoS difficult. In this paper, we address the heterogeneity problem from the perspective of knowledge engineering. We propose a QoS...

In this paper, we are proposing an Inter-domain traffic engineering architecture over a Bandwidth Broker (BB) supported Diffserv internet. The main components of our architecture are a novel inter-domain QoS routing architecture, the addition of an explicit path setup capability to the Simple Inter-domain Bandwidth Broker Signaling (SIBBS) protocol, and inter-domain label switched path (LSP) se...

In this paper a new QoS protection paradigm to extend and enhance current QoS routing is formalized and supported by experiments. Previous QoS routing algorithms considers protection as a secondary aspect and uses QoS routing objectives, such as minimizing resources or request rejection, to route backup paths. This work defines new QoS objectives to route backup paths. QoS protection concept is...

In this paper, we describe an adaptive QOS mapping scheme where the QOS parameters of applications are mapped into resource requirements dynamically, and the resources for the applications are reserved based on the measured resource utilization. Real-Time Mach provides resource reservation facilities that are suitable for supporting the adaptive QOS mapping scheme, and we show the e ectiveness ...
