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

Colocation plays a bigger role

Downsize or EliminateEnterprise owned Data Centers

Internet APN

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
