CyberCash's problem
- High availability
- High responsiveness
Working with > 1 IP provider (1 T1 line is fine)
Multiple providers are required
- Cutover works poorly
- routes are not always accurate
- Cutover times sometimes long
- Connected and working but not always reachable
Coordination
- Redundancy versus capacity
- Don't want to pay double for higher availability
- Need shared models of service
- Would like to see joint offering
[One provider sold them a 0 CIR and the protocols in place don't
make cutover transparent.]
