The spread of virtual environments is setting forth a new set of challenges in the management of system resources for guaranteeing Quality of Service (QoS). This paper describes an implementation of end-user QoS control to a Distributed Virtual Environment Platform DVECOM [Choukair00]. In particular, we describe how to guarantee mandatory properties such as synchronization and consistency and how to reduce the impact on the application in case of sudden overload in the system and how we master this degradation to guarantee a smooth degradation according to the end user requirements. This representation degradation is driven by the user's choices and profile selected through the offered rendering strategy API. We also present our evaluation of the QoS implementation, describing some interesting results we achieved in a simulation of a collaborative work in the system.
