Service Assurance—A key enabler

If you can’t assure the service in an agile way, you can’t virtualize it.

Key Takeaways

NFV and SDN hold promise

• Service agility, faster time to market, lower operational costs

But also create challenges

• Real-time management across physical and virtual realms

• Shared infrastructure, multiple abstractions

• Vendor-specific ecosystems open to vertical integration

Orchestrated Service Assurance enables QoE as a competitive differentiator

• Dynamic & On-demand: network, service and user context-aware

• Efficient: automated, scalable & consumption-based

• Future proof: open interfaces and vendor agnostic
