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 Services address all of the above 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 MEF is addressing the top 3 items Source: MEF-Vertical Systems Group 3
: Service Provider Threat or Opportunity? Will Services cannibalize MPLS VPN Services? Is it possible to deliver a good SLA using an OTT service? Can services really bring new sites in minutes instead of weeks? Can services connect off-net site without peering agreements? Services provide much more than connectivity Source: MEF-Vertical Systems Group 4
