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

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

Confluence of Key Technologies will Transform WANs

Colocation – now a much bigger Intranet Role

Abundant CheapBandwidth

WAN Virtualization makes Internet reliable enough for Ent. use

Great Connectivity

Colocation plays a bigger role

Downsize or EliminateEnterprise owned Data Centers

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
