IPv6 introduces some additional features (like flow label) and the current support for QoS mechanisms in IPv6 implementations approaches the corresponding QoS support in IPv4. Therefore, a number of tests with DiffServ QoS mechanisms applied on IPv6 traffic have been carried out on a testbed created specifically for this purpose, in order to validate the mechanisms and evaluate the router?s overall performance. Our evaluations cover the load incurred to the routing devices from the implementation of the mechanisms, the level of support for QoS IPv6 features and the comparison of performance over IPv4 and IPv6. %B The Second International Workshop on Advanced Architectures and Algorithms for Internet Delivery and Applications (AAA-IDEA 2006), Pisa, Italy %8 10 October %G eng
