This webinar talks about the Service Provider Experiences with NFV: The Good, the Bad, and the Ugly.

Service providers have been deploying and attempting to deploy network functions virtualization (NFV) for over a year now, and it hasn't been as easy or simple as it appears in slideware. A majority of operators that planned to commercially deploy NFV in the past year still have not done so, citing immature technology and fitting NFV into existing networks and processes as the major stumbling blocks. But many operators that have rolled out NFV say the technology is good enough to deploy in contained domains, and they've learned a lot. Of course, deploying new services using NFV without disrupting existing revenue-bearing networks is the big challenge. This webinar weighs in on the good experiences to repeat, the bad experiences to learn from, and some ugly paths to avoid.

Key Topics for Discussion:
• Ensuring the performance of end-to-end services that cross both physical and virtual networks
• What happens when a single customer service chain uses virtual network functions (VNFs)
• The top 5 issues to overcome when commercially deploying NFV-based services
• The top 5 NFV use cases this year and next
