Due to the increasing requirements on quality of service (QoS) for multimedia applications, wide area networks must be able to provide end-to-end performance guarantees. The ATM protocol, which offers an extensive traffic management functionality, achieves QoS in networks by providing various categories with different quality of service features. However, it is expensive and incompatible to the existing Internet infrastructure. On the other hand side, the ”best effort” service of the IP protocol is not able to fulfill these demands.
