Congestion based resource sharing in multi-service networks

Boris Jukic, Robert Simon, Woan Sun Chang
2004 Decision Support Systems  
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.  ...

Quality of Service of Grid Computing: Resource Sharing

Xian-He Sun, Ming Wu
2007 Sixth International Conference on Grid and Cooperative Computing (GCC 2007)  
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.  ...

Utility-based resource allocation and scheduling in OFDM-based wireless broadband networks

Guocong Song, Ye Li
2005 IEEE Communications Magazine  
We also provide a solution that can efficiently allocate resources for heterogeneous traffic with diverse QoS requirements.  ...  We present a cross-layer resource management framework leveraged by utility optimization.  ...  Fairness and Rate-Based Utility Optimization Since best-effort traffic has no specific QoS requirements, fairness among those users sharing the same bandwidth is one of the most important criterion.  ...

QoS standards for ip-based networks

Y. Maeda
2003 IEEE Communications Magazine  
Traditional IP networks take a best effort approach to quality, affording users a fair share of the available betwork resources, but not ensuring that any particular performance levels will be met.  ...  Given the current abundance of bandwidth on many routes, the best effort paradigm even meets the needs of many users today for interactive voice telephony and other real-time applications.  ...  Traditional IP networks take a best effort approach to quality, affording users a fair share of the available betwork resources, but not ensuring that any particular performance levels will be met.  ...

Extending a Best-Effort Operating System to Provide QoS Processor Management [chapter]

Hans Domjan, Thomas R. Gross
2001 Lecture Notes in Computer Science  
The benefits of QoS network features are easily lost when the endnodes are managed by a conventional, best-effort operating system.  ...  The system is targeted at applications with frequently changing resource demands or recurring, though non-periodic resource requests.  ...  This R-Scheduler, which extends the notion of QoS from the network into the OS, co-exists with a best-effort scheduler and has been implemented with modest effort for NetBSD and ported to Linux.  ...

Enhanced Adaptive Mechanisms to Improve QOS in Distributed Multimedia Applications

Dr. Syed Abdul Sattar, Mirza Anwarullah Baig
It is essential that QoS is guaranteed in a system, considering distributed system area, the transport protocol and themultiservice network.  ...  Quality of Service (QoS) in distributed multimedia systems provides a unifying theme on which the functions and facilities of the new integrated standards can be constructed.  ...  Commonly, best-effort applications have a simple, onedimensionalquality model or no notion of quality at all. Hard Guarantees In a guaranteed system, the user gives the required QoS.  ...

List multi-coloring based fair channel allocation policy for self coexistence in cognitive radio networks with QoS provisioning

Mishra Vishram, Lau Chiew Tong, Chan Syin
The former problem is solved by spectrum sensing while the latter problem requires complex techniques.  ...  Detecting an incumbent user along with self-coexistence has become one of the important aspects of the cognitive radio.  ...  Resource Share Calculation Since each BS has different requirement of bandwidth depending upon the priorities of applications, each BS calculate its share of channel resource.  ...
