On-Demand
and
Elastic
Services
• Long service lifecycle
• Manual service activation
• Infrequent changes
• Proprietary and Hard to Program
• Short service lifecycle
• Automated service activation
• Frequent changes (elastic)
• Open and Programmable
CSP networks must evolve to support this new reality

Enterprise Customers Challenges in the WAN
Enterprise customers want reduced costs and independence from CSP
Pains with WAN Links
• High cost of IP/MPLS-based WAN Links
• CSP dependency
• No seamless way to add capacity and
Physical Network Functions
• Desire of using more BB-based WAN
Links
• Lack of Security and Reliability when
using BB-based WAN Links
• Manual and device-level configurations
require highly skilled engineers
• Slow Time to Market and Time to
Revenue
Pains with Physical Appliances
• High cost of managing several Physical
Appliances in remote locations (truck
rolls, logistic, inventory, etc.)
• CSP dependency
• No seamless way to add capacity and
Physical Network Functions
• Manual and device-level configurations
require highly skilled engineers
• Slow Time to Market and Time to
Revenue

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

Giving the Control Back to CSPs
CSP should offer enterprise customers managed SD-WAN
SD-WAN Technology Risk
• Is the Enterprise customer choosing the
most suitable SD-WAN solution in order to
address its needs?
• Does the Enterprise customer has the
expertise to deploy, manage, troubleshoot
the SD-WAN solution?
• Will the Enterprise customers applications
hit the performance levels they need?
• Do the SD-WAN Vendors have local
inventory/dispatch if CPE fails in an
international location?
• May the chosen SD-WAN solution by the
Enterprise customer become a proprietary
dead end?
Managed Services Mitigation
• CSP has investigated available SD-WAN and
NVF solutions for functionality, security and
resilience
• CSP handles end-to-end network and
service design, deployment, operation and
maintenance
• CSP delivers underlying IP/MPLS networks
in order to ensure the performance levels
the Enterprise customers need
• CSP maintains global operating companies,
sourcing partnerships
• CSP can take the risk of CPE ownership
over the length of a contract

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
