Enterprise WANsa NEW Architecture
WAN Virtualization
does for WANs what RAID did for storage
lots more bandwidth
hugely lower WAN service cost
WAN Virtualization plus other existing technologies enable a
revolution
in building Enterprise WANs

Massively more bandwidth at remote and core locations
Huge WAN service cost savings
Both lowered monthly WAN access bills, as well as massively lower cost/bit
Far greater reliability, WAN application performance,
and

predictability
Network complexity further centralized
Greater network diversity
Added reliability, and…
leverage with Telecom Service Providers
