Providing Quality of Service (QoS) in the Internet is currently the most challenging topic for researchers, industry and network providers. Now, the only available service in the Internet is the best effort service, which assumes traffic is processed as quickly as possible, but there is no guarantee as to timely or actual delivery. On the other hand, there is pressure to offer new applications in the Internet (like VoIP, videoconferencing, on-line games, e-commerce, etc.) but this requires some packet transfer guarantees from the network (e.g., low packet transfer delay, low packet losses). To meet these requirements, new architectures for providing IP- based QoS in the Internet are proposed: Integrated Services (IntServ ) and Differentiated Services (DiffServ ). However, these architectures need some enhancements to provide adequate solutions for resource management, signaling, traffic engineering, traffic handling mechanisms, etc. In the European research comm
