Integrated Services (int-serv)
Supplement Internet Architecture with:
- Services: guaranteed delay, controlled load
- New signaling protocol: RSVP + admission control
- Shaping at edge nodes combines with packet classification and scheduling/buffer management at routers to provide local delay and bandwidth guarantees.
- Specs for parameters (flow-spec), classification (filter-spec)
Critique: non-scalable, no control over routing vagaries, no feedback support
