The home network is an open, heterogeneous and distributed environment where ensuring multimedia ap-plications' quality of service is a main concern. Mechanisms to reserve resources (CPU, memory, network) and architectures using them already exist. However, they require to modify the devices or the applications and they do not take into account the heterogeneity of the home network. This paper presents a non-intrusive and adaptable resource management framework. This framework is developed upon an architecture, customized for the actual devices. This architecture uses global components that delegate to local components the management of local resources. These components rely on the resource reservation mechanisms provided by the Linux operating system in order to guarantee the resources to the applications. The framework has been implemented on real devices (PCs, laptops and embedded multimedia devices), bridged with wireless and Ethernet networks. The evaluations of the framework show that reservations are guaranteed even if noise is generated on the resources, which also guaranties the expected quality of service.
