Next-generation 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 lower networking OpEx
• This NEW architecture provides pragmatic, evolutionary path to leveraging Cloud Computing lower overall IT, applications CapEx, OpEx
Mainframe/Minicomputerstorage - 1980s
First we hadAlong comes key

WAN Virtualization:Doing for WANs what RAID did for Storage
30x to 100x Bandwidth per $
40% to 90% WAN Cost Savings
More Reliable than Single Vendor FR/MPLS
WAN Virtualization Benefits
Private WANs too Expensive;The Problem: Public WANs not Reliable Enough

Massively more bandwidth at remote and core locations
Huge WAN service cost savingsBoth lowered monthly WAN access bills, as well as massively lower cost/bit
Far greater reliability, WAN application performance, and application performance predictability
Network complexity further centralized
Greater network diversity Added reliability, and… leverage with Telecom Service Providers
