As networks grow in scale and complexity, the edge of the network is increasingly seen as the first line of defense for security, traffic shaping, quality monitoring and other network functions. Cloud software technologies and Network Function Virtualization (NFV) have created opportunities to migrate network functions from the core of a network to the edge. During this session, we'll look at the Intelligent Edge as a network strategy, covering the evolution, use cases and drivers made possible with low-cost NFV software. Topics covered in this session: - Cloud adoption - Network Function Virtualization - Trends in Edge Computing resources - Use Cases - Your Questions

5. 5
Challenges for CSPs
• Agility - Deploying New Services
• Competing with OTT Services
• Network Security
• Reliability & Scalability
• Network Traffic Management
• Reduction of CPE SKUs
• Cost of Truck Rolls

6. 6
The Dumb Edge
• Customer Access
• Service Provider Termination
• Provides Point of Demarcation
• End of Responsibility for CSP
• “Anything beyond this point is
your problem”
• No intelligence

7. 7
The Smart Edge
• “Smart Jack”
• Allowed remote Loop-back
testing and diagnostics
• Fixed function device
• Firmware-based
• Difficult / Impossible to update
without truck roll
• Can’t be expanded
• No new capabilities

20. Case Study
About Marcatel
– Founded in 1994 in
Monterrey, Mexico
– Services over 100 countries
– 4,600 km of fiber
– Offers cloud, Internet,
contact center and SIP
Trunking

21. Case Study
Challenges:
– “Payday Problem” – too much traffic on payday
– Needed call rate limiting for SIP trunks. Application to
gracefully limit outbound calls from customer’s dialers.
– Upgrades to the core of their network would be very costly
– Made more sense to manage traffic at the edge of the
network
– Modifications to routing and Display Name are difficult
