Recently, packet networks are enabling the integration of heterogeneous traffic with a wide range of characteristics that extend from video traffic with stringent QoS requirements to best- effort traffic requiring no guarantees. QoS guarantees can be provided in packet networks by using the proper packet scheduling algorithms. In this book, we propose a new priority assignment scheduling algorithm, Hierarchical Diff-EDF, which can meet the real-time needs while continuing to provide best effort service over heterogeneous real- time network traffic. The Hierarchical Diff-EDF service...
