IN PRESS IPv 6 deployment : Real time applications and QoS aspects *
نویسندگان
چکیده
This paper gives an overview of the issues related to the QoS mechanisms under IPv6 and the transition of applications to the new Internet protocol. We describe the implementation and testing of a QoS service on IPv6 networks, which is based on the DiffServ architecture (expedited forwarding) and provides strict priorities to packets that are produced from real time applications. The service was implemented and tested at the 6NET large-scale IPv6 network, and additional advanced testing was performed in a local testbed. We present and analyze the results from our tests under a number of different scenarios. In addition, we focus on issues regarding application transition to IPv6 and we briefly discuss as a case study the transition of OpenH323 protocol stack to support IPv6. We also discuss the usage and the expected impact of the new Flow Label field in the IPv6 header. q 2005 Elsevier B.V. All rights reserved.

A New Fairness Index and Novel Approach for QoS-Aware Resource Allocation in LTE Networks Based on Utility Functions
Resource allocation techniques have recently appeared as a widely recognized feature in LTE networks. Most of existing approaches in resource allocation focus on maximizing network’s utility functions. The great potential of utility function in improving resource allocation and enhancing fairness and mean opinion score (MOS) indexes has attracted large efforts over the last few years. In this p...

متن کاملPromisQoS: An Architecture for Delivering QoS to High-Performance Applications on Myrinet Clusters
Clusters of workstations are being extensively used for solving computationally intensive scientific problems. However, there is limited support for Quality of Service (QoS) based distributed computing on commercial offthe-shelf (COTS) clusters. This limitation has restricted successful deployment of distributed real-time highperformance computing applications to customized and dedicated embedd...
متن کاملThe Design and Performance of Component Middleware for QoS-enabled Deployment and Con guration of DRE Systems
QoS-enabled component middleware can help reduce the complexity of deploying and con guring real-time aspects, such as priorities and rates of invocation. Few empirical studies have been conducted, however, to guide developers of distributed real-time and embedded (DRE) systems in choosing among alternative designs and performance optimizations. This paper makes two key contributions to researc...
متن کاملImproving Success Ratio in Multi-Constraint Quality of Service Routing
Multi-constraint quality-of-service routing will become increasingly important as the Internet evolves to support real-time services. It is well known however, that optimum multi-constraint QoS routing is computationally complex, and for this reason various heuristics have been proposed for routing in practical situations. Among these methods, those that use a single mixed metric are the mo...
