Hierarchical Resource Scheduling

• Requirements:

  • Real-time
    • QoS for leaf classes (i.e., delay, bandwidth)
  • Link-Sharing
    • service sharing among classes
    • “proper” distribution of excess service among sibling classes (e.g., fair)
  • Priority
    • decoupled delay/bandwidth allocation
  • Statistical sharing
    • encourage adaptation by end-system
