Summary
Introduce a QoS model for aggregate traffic with large spatial granularity
Propose a set of mechanisms to implement it
- high service assurance
- high resource utilization
Key ideas: separation of two levels of differentiation
- user level differentiation: destination/path independent
- packet level differentiation : destination/path dependent
Future work
- use path cost at
- egress nodes for active queue management
- end systems for better end-to-end congestion management
- provide support for
- receiver based payment, multicast
