Top Purchasing Drivers and Business Challenges for Dynamic Network Connectivity Services

• MEF-Vertical Systems Group survey of 50 Service Providers and 37 Technology Providers

• Survey participants from Product Mgmt./Planning/Marketing, Network/System Architecture and Engineering

Top 5 Purchasing Drivers

• Faster Service Provisioning

• Ability to scale the network on-demand

• Business agility to adjust to market dynamics

• Ability to dynamically tailor to application needs

• Lower network connectivity service costs

Top 5 Deployment Challenges

• Current OSS/BSS systems are inadequate

• Integration with legacy infrastructures

• Standards are insufficient or incomplete

• Network operators not strategically committed

• Funding constraints for deployment

SD-WAN Services address all of the above MEF is addressing the top 3 items

• Will SD-WAN Services cannibalize MPLS VPN Services ?

• Is it possible to deliver a good SLA using an OTT SD-WAN service ?

• Can SD-WAN services really bring new sites in minutes instead of weeks ?

• Can SD-WAN services connect off-net site without peering agreements ?

SD-WAN: Service Provider Threat or Opportunity ?

SD-WAN Services provide much more than connectivity

SD-WAN Service Tunneled over Multiple ISPs

• SD-WAN service across multiple ISPs to achieve the WAN resiliency

• Use case could be applied to a larger SD-WAN managed service deployment

• Multiple ISPs and multiple Internet WANs offers better SLA
