Business Case
Cost
• Substitute higher cost links or devices for lower cost
• Lower cost of management, troubleshooting
• Leverage Complete Communications for financial analysis
Agility
• Focus on how automation and policy abstraction empower the
organization to innovate faster while transforming the customer and
workforce experience
Focus
• Provide quantifiable metrics associated with expedited mean time to
detection, mean time to innocence and mean time to repair
Performance
• Quantify frequency and cost associated with outages
• Reduce number of outages affecting user performance
• Improve application performance
Security
• Application relevant topologies
• Segmented virtual WANs and security service chains

Choosing the right solution
• Layer 3 VPN overlay for hub-and-spoke deployments
• Layer 3 and 7 policy and performance based routing
• Transport independence across a variety of connection types
• Zero touch deployment with support for templated configurations
• Multicast support over WAN

Customer Industry Challenge Solution
Retail
High cost, slow change, limited
flexibility
60-70% cheaper broadband at high bandwidth,
centralized control, full visibility.
Financial
Needed more bandwidth and
guaranteed network uptime for a new
teller application
Dollar cost averaged the bandwidth cost down using a mix
of transport (MPLS, Broadband, LTE). Traffic now uses the
optimal network path to avoid downtime and slowdowns.
Tech
Slow performance and MPLS outages
provided an expensive and poor user
experience
Monthly savings reduced the cost per Mbps by more than
80%. Diverse circuits improve the reliability of the global
network, with more than half of Agilent’s sites doubling
WAN redundancy.
Healthcare
With an MPLS contract renewal
approaching, Cigna wanted the
flexibility to change carriers without a
massive technology shift
Gained back control of its control plane and created the
Cigna Service Provider Agnostic Network.
Healthcare Security and high network cost
Satisfied strict security and audit requirements and
provided greater flexibility for partnerships and secure
clinical solutions. Cost reductions with the removal of
remote site voice equipment and expensive PRIs, aging
WAN acceleration equipment and maintenance.
Energy
Scale to support evolving field
operations, and support cloud migration
and application SLAs
Provided 30-60% savings in overall bandwidth costs.
Enabled faster response to acquisitions, divestitures and
policy changes.
