Summary: Network Stability: effects on communication
Global stability for the network roundtrip time:
- Choosing the best path and communicating over it is feasible (done today).
Some path is stable during its roundtrip time:
- Communicating over all paths in parallel (flooding) - inefficient but reliable.
- Guessing the stable path based on past behavior (assuming correlation ??) - risky but possible (new algorithmic ideas)
No stability, no correlation: links go up & down:
- Communication over all paths using store & forward.
- Virtual path guessing possible (new algorithmic ideas)
