Congestion based resource sharing in multi-service networks
2004
Decision Support Systems
Preserved Fulltext
The internet traffic is increasingly composed of streams of packets with very diverse quality of service (QoS) requirements: from those containing standard, best-effort traffic, such as e-mail or http ...
We describe a measurement-based approach for QoS path pricing that results in improved resource allocation policies between QoS and best-effort traffic. ...
The level of resource sharing between QoS and best-effort traffic can be determined by the objective of maximizing user value or by a network policy decision. ...

In this study, we conduct a thorough study of QoS of distributed computing, especially on Grid computing where the requirement of distributed sharing and coordination goes to the extreme. ...
The non-deterministic characteristic of the resource availability in these new computing platforms raises an outstanding challenge: how to support Quality of Service (QoS) to meet a user's demand? ...
For example, Condor and Seti@home support best-effort QoS policy. They can detect resource availability by monitoring local users' activities on mouse and keyboard. ...
