7. Cloud Ready Network Architecture
Addresses network requirements in five critical areas:
1. High bandwidth / low latency
2. Convergence to Ethernet
3. Support for agile workloads
4. Build-out and management
5. Green / low power
Cloud Ready “Truths”:
• Solutions should be OPEN – with
multi-vendor support
• Customers prefer incremental
deployment, not rip and replace
