Evaluation of the Fast Handover Implementation for Mobile IPv6 in a Real Testbed

by Loránd Jakab, René Serral-gracià, Jordi Domingo-pascual
"... Fast Handovers is an enhancement to the Mobile IPv6 protocol, currently specified in an IETF draft, which reduces the handover latency. This can be beneficial to real-time applications. This paper presents a novel implementation of Fast Handovers and an analysis of the handover. Using a real testbed ..."

Performance Evaluation of the Impact of QoS Mechanisms in an IPv6 Network for IPv6-Capable Real-Time Applications

by Ch. Bouras, A. Gkamas, D. Primpas, K. Stamos
"... This paper describes a Quality of Service (QoS) service on an IPv6 domain that aims to service aggregates of real-time traffic with minimum delay, jitter, and packet loss. It contains results from the tests that were performed in order to configure and evaluate the QoS mechanisms. As an actual examp ..."

that took advantage of the QoS mechanisms. This QoS service uses the Modular QoS CLI (MQC) mechanism and especially the Low Latency Queue feature (LLQ) in order to treat packets from real-time applications. KEY WORDS: Quality of Service; IPv6; OpenH323, real-time applications. 1.

Modeling and performance analysis for IPv6 traffic with multiple QoS classes

by Liren Zhang, Li Zheng , 2001
"... This paper focuses on the modeling and performance analysis for IPv6 traffic with multi-class QoS in virtual private networks (VPN). The multi-class QoS is implemented on differentiated service basis using priority scheme of 4 bits defined in the packet header of IPv6. A VPN-enabled IP router is mod ..."

QoS based Real Time Audio Streaming on IPv6 Networks

by Stefan Schmid, Andrew Scott, David Hutchison, Konrad Froitzheim , 1998
"... Live audio streaming is an important component of Internet multimedia. The currently deployed Internet oers poor support for such streams due to the lack of Quality of Service (QoS) capabilities. However, IPv6, the new Internet Protocol has now included provision for QoS. The introduction of a ow la ..."

Applications based on IPv4 and IPv6 Networks

by Vahid Ghoreishi, Shahram Mohammadi
"... Abstract—With the expansion of Internet, the current protocol address space (IPv4) is faced with a shortage and the new generation Internet (IPv6) is raised in order to solve this problem. Also with increasing interest of users in real-time and multimedia applications, the Internet and how to impl ..."

to implement these applications to improve the quality of service (QoS) has become a significant challenge. In this paper, a network with both IPv4 and IPv6 protocols is simulated by using OPNET Modeler and implementation of QoS is tested on it. Packet loss, end-to-end delay and jitter were evaluated
