Agenda

Before we begin…


Legacy WAN Architecture

• Two or more circuits

• All MPLS, or, MPLS and INET/LTE

• Active/Standby Redundancy

• Internet/SaaS access backhauled via DC

Factors to consider before migration

Controllers

• Deployment Model

• On-Prem

• Cloud-hosted

• Redundancy

• Scale

Datacenter

• New/existing circuits

• Design• Dual MPLS/Hybrid/LTE

• Full mesh/Hub-spoke/Arbitrary

• Routing

• Traffic path during migration

• Policy requirements• App-route/SLA

• Traffic Engineering

• Service Advertisement

• QoS

Branch

• New/existing circuits

• Identify working applications/services

• Design• Dual MPLS/Hybrid/LTE

• Full mesh/Spoke-hub/Arbitrary

• Policy requirements• DIA/Backhaul to DC

• Regional breakout for services

• Access to SaaS/IaaS
