Emerging QOS-COS support from Service Providers
MultiProtocol Label Switching (MPLS)
- Label switching routers use labels carrying forwarding & resource reservation semantics to construct label-switched paths carrying aggregated traffic of a particular class/quality
RSVP extensions to improve scalability, deployment
- Map RSVP flows onto IEEE 802.1p, DiffServ classes
- Aggregate flows according to traffic classes
Traffic engineering
- Direct/switch aggregated rather than individual flows along specific forwarding path
