The document discusses the key requirements for successful network function virtualization (NFV) deployments. It emphasizes that NFV solutions need to provide: performance at scale through optimized hardware; ease of deployment through cloud-native software on commercial off-the-shelf servers; and security across infrastructure, orchestration, and devices. The document also stresses the importance of multi-vendor collaboration, a focus on practical use cases like universal customer premises equipment, and an agile development approach to overcome challenges in bringing NFV from labs to large-scale production networks.

What’s Needed? Multi-Vendor Ecosystems!
• Insistence on different
suppliers at each layer
• Requires cooperation between
operator, suppliers AND
customer
• Raises importance of APIs and
ability to cooperate
• Business case has to work for
EVERYONE

Summary – 2017 Is the Year of NFV
Deployments!
… especially for operators who can solve the problems
encountered when taking NFV from the lab to large-scale
rollout
That means collaborating with partners who can offer:
• Software-based services
• Ecosystem of partners
• Solutions for deployment issues
• Optimization of low-cost COTS servers
• Security at multiple layers
• Partnership in an Agile and DevOps model
• Focus and a sense of urgency!
