• Long service lifecycle• Manual service activation• Infrequent changes• Proprietary and Hard to Program

• Short service lifecycle• Automated service activation• Frequent changes (elastic)• Open and ProgrammableCSP networks must evolve to support this new reality

Long Term NFV Vision

Just imagine an app store with on-demand and elastic network functions

Software Defined Networking (SDN)

SDN decouples the control plane from the forwarding plane

Enterprise Customers Challenges in the WAN

Enterprise customers want reduced costs and independence from CSP

CSP Challenges in the WAN

• SD-WAN vendors going directly to CSP’s enterprise customers• SD-WAN vendors promising enterprise customers reduced costs

and independence from CSP• Enterprise customers threatening CSP with SD-WAN solutions• CSP sees an increased demand of BB-based WAN links from

enterprise customers• CSP sees a decreased demand of IP/MPLS-based WAN links from

enterprise customers

CSP’s revenue from traditional VPN services may be at risk

Industry SolutionsSD-WAN (coming from enterprise)

• Less pain with WAN Links

NFV vE-CPE (coming from CSP)

• Less pain with physical appliances

The Issue: Each Is a Point SolutionSD-WAN (coming from enterprise)

• Leave the problem of L4-L7 physical appliances unsolved

NFV vE-CPE (coming from SP)

• Leave the problem of CSP dependency unsolved

The Issue: The Two May Weaken Each OtherSD-WAN (coming from enterprise) NFV vE-CPE (coming from SP)

NFV vE-CPE’s CSP dependency spoils SD-WAN’s benefits

Summary

• SD-WAN takes the SDN advantages found in DC, and applies them to WAN solutions for enterprise customers• Ease of deployment and use• Dynamic path control to optimize traffic among multiple WAN

connections• Application classification to monitor performance and policy-based

management • For enterprises SD-WAN promises reduced costs and independence from

service providers• For CSP SD-WAN enables new service revenue selling managed SD-WAN

services and enables new off-net revenue

ADVA Optical Networking can deliver a unique and comprehensive SD-WAN solution
