Abstract

This paper investigates the problem of making QoS guarantees available in access devices such as edge routers, that are commonly deployed in today´s IP networks. We propose a specific design which we evaluate by carrying out a complete implementation, whose performance we then measure in the context of an experimental testbed. The results indicate that a reasonable level of service differentiation, i.e., rate and delay guarantees, can be provided with a minimal impact on the raw packet forwarding performance of edge devices
