Dell NFV Summit 2015 are now available. Steve Wright's 7 Fallacies of NFV talk describes the importance of managing network resources in an NFV stack. The diagram above shows the complex network data paths that result from NFV as packets flow between virtual functions across physical and virtual switches.
Fallacies of Distributes Computing apply to NFV, highlighting the importance of effective management of network resources for effective NFV deployment.
Another paper, Demystifying NFV Infrastructure Hotspots by Ramki Krishnan, Anoop Ghanwani, and Michael Tien, demonstrates how industry standard sFlow instrumentation build into physical and virtual switches can provide the comprehensive real-time analytics needed to manage NFV deployments.
