Quality of service in the Future Internet

Whatever the Network of the Future turns out to be, there is little doubt that QoS will constitute a fundamental requirement. However, QoS issues and the respective solutions will not remain unchanged. New challenges will be raised; new ways of dealing with QoS will be enabled by novel networking concepts and techniques. Thus, a fresh approach at the QoS problem will be required. This paper addresses QoS in a Future Internet scenario and is focused on three emerging concepts: Network Virtualization, enabling the coexistence of multiple network architectures over a common infrastructure; In-Network Management, improving scalability of management operations by distributing management logic across all nodes; the Generic Path based on the semantic resource management concept, enabling the design of new data transport mechanisms and supporting different types of communications in highly mobile and dynamic network scenarios.
