Quality of Service Vertical and Horizontal Integration in Active Nodes

In this paper we focus on possibilities of quality of service mechanisms implementations in active routers. We show that a different location generates a different resulting QoS. Indeed, two types of QoS can be provided in active network: one that provides "classical" network QoS and one that provides more computing resources to priority flows. We describe a number of implementations we have realized in ANTS and Tamanoir active nodes. In these implementations based on flow differentiation, we have developed several schedulers. We present experimentations realized in order to validate our implementations. In these experimentations, we emphasize on the two kinds of QoS provided. We show the interest of our innovative and efficient approach
