H-GPS and H-PFQ
Hierarchical Generalized Processor Sharing model
- proven end-to-end delay bounds for guaranteed traffic
- ideal semantics for hierarchical resource management
- QoS met for all traffic classes simultaneously
- friendly to bursty and adaptation sources
- scalable mechanism for estimating available bandwidth by adaptive applications
- no punishment in the future for using excess service in the past
Hierarchical Packet Fair Queueing Algorithm
- accurately and efficiently approximates H-GPS model
- first algorithm to support real-time, link-sharing simultaneously
