TY - CONF T1 - Issues for the Performance Monitoring of an Open Source H.323 Implementation Ported to IPv6 – Enabled Networks with QoS Characteristics T2 - The 2003 International Conference in Internet Computing (IC 2003), Las Vegas, Nevada, USA Y1 - 2003 A1 - Christos Bouras A1 - Apostolos Gkamas A1 - Kostas Stamos A1 - Dimitris Primpas A1 - A Karaliotas AB - OpenH323 is an open source H.323 implementation that has been ported to IPv6. It therefore presents an opportunity to perform experiments and compare the performance of an H.323 application when using the IPv4 stack and when using the IPv6 stack. In this paper we initially introduce briefly the porting procedure and the methodology we used in order to achieve it. We then present the appropriate experiments that have to be performed in order to comparatively evaluate the IPv4 and IPv6 protocol stacks. We also present the results of some initial experiments comparing IPv4 and IPv6 performance and the conclusions that they can lead us to.
