Scalable QoS for XCAST Using Differentiated Services Architecture

Policy Based Architecture for QoS over Differentiated Services Network

Current Internet architecture is based on the Best Effort (BE) model, where packets can be dropped indiscriminately in the event of congestion. This architecture attempts to deliver all traffic as soon as possible within the limits of its abilities, but without any guarantees about throughput, delay and packet loss etc. Though such a model works well for certain traditional applications such as...

Differentiated MPLS Services (DMS) Architecture with QoS Recovery

The Internet is evolving from best-effort service toward an integrated or differentiate service framework with Quality of Service (QoS) assurances that are required for new multimedia service applications. IP/MPLS based control plane combined with wavelength-routed Dense Wavelength Division Multiplexed (DWDM) optical network is viewed as a very promising approach for realizing future re-configu...

Absolute QoS Guarantees in a Relative Differentiated Services Architecture

In this paper we propose a new architecture that provides absolute QoS guarantees for the users, requires only per-class state at the edges of the network, generates only a small amount of overhead, and uses relative differentiated services architecture inside the domain. In our proposal the service provider offers a smaller number of classes for the end-users (or for other ISP-s) with absolute...

Architecture and Experimental Framework for Supporting QoS in Wireless Networks Using Differentiated Services

Architecture and Algorithms for Scalable Mobile Qos Architecture and Algorithms for Scalable Mobile Qos

Supporting Quality of Service is an important objective for future mobile systems, and requires resource reservation and admission control to achieve. In this thesis, we introduce a scalable scheme to admission control termed Virtual Bottleneck Cell. Our approach is designed to scale to many users and hand-o s, while simultaneously controlling \hot spots". The key technique is to hierarchically...
