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

Colocation – now a much bigger Intranet Role

Abundant Cheap

WAN Virtualization makes Internet reliable enough for

Great Connectivity

InternetSlide11

Colocation plays a bigger role

Downsize or Eliminate

Enterprise owned Data Centers

InternetSlide12

Internet

 APN

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

application performance

predictability

Network complexity further centralized

Greater network diversity

Added reliability, and…

leverage with Telecom Service Providers
