This paper presents our work in the framework of the 6NET project, regarding the design, implementation and testing of a QoS service in a large-scale IPv6 network. The DiffServ mechanism for providing QoS guarantees, is generally preferred over IntServ. However, the current support for QoS mechanisms in IPv6 implementations still lags behind QoS support in IPv4. Furthermore, the new Internet Protocol introduces a different network environment in many aspects and therefore the QoS services should be specifically designed and evaluated for IPv6. In order to evaluate this different behaviour, large-scale experiments have been carried out within the scope of the 6NET project. This paper describes the results from the experimentation with the DiffServ mechanism on a large-scale native IPv6 network that aims to service aggregates of real time traffic with minimum delay, jitter and packet loss.
