and evaluation of DiffServ QoS mechanisms over IPv6
and IPv4 in dual stack software based platforms. 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 IPv6.1 aBouras, Christos1 aStamos, Kostas1 aPrimpas, Dimitris  uhttp://telematics.upatras.gr/telematics/publications/ipv6-qos-testing-dual-stack-networks?language=el
