To Share rather than To Pay
A very short presentation, in five points:
To variable delay:
To packet losses:
To congestion:
- Adapt compression ratio (IVS)
- Hierarchical encoding
- Dead reckoning (DIS)
Variable networking conditions
- 10 base T, 100 base T
- ATM, MYRINET, Waveband Mux
- GSM, Packet Radio
Reasons to adapt
- Graceful failure
- High Fidelity
Network conscious applications
- Work without reservation
- Adapt to reservation !
Priviledges of reservation
- knowledge of user
- fades with distance
- or requires payments...
Opposition to equality ?
- different types of needs (TOS)
- Scott's inflexion
What of open heart surgery ?
- needs priority,
- not reservation
- not admission control
Credit card in the slot
- Pay per view TV
- Pay local provider
Equal share per user
- Fair queuing per destination
- Select interesting source
Bandwidth Galore ?
- Pass it to the user,
- Avoid state explosion
- Avoid bean counting.
Constrained channel ?
