GPS and H-GPS Properties
Proven end-to-end delay bounds for guaranteed traffic
Adaptation friendly
- no punishment in the future for using excess service
- scalable technique for estimating excess bandwidth for adaptive applications
GPS: guaranteed service for each flow
H-GPS: guaranteed service for all classes
- leaf class: individual flow
- interior class: traffic aggregate
- QoS met for all traffic classes simultaneously
- ideal semantics for hierarchical resource management
