-Scenario Overview
+NFV and virtualized high performance applications, such as video processing,
+require a "fast data stack" solution that provides both carrier grade
+forwarding performance, scalability and open extensibility, along with
+functionality for realizing application policies and controlling a complex
+network topology.
+A solution stack is only as good as its foundation. Key foundational assets for
+NFV infrastructure are
+ * The virtual forwarder: The virtual forwarder needs to be a feature rich,
+ high performance, highly scale virtual switch-router. It needs to leverage
+ hardware accelerators when available and run in user space.
+ In addition, it should be modular and easily extensible.
+ * Forwarder diversity: A solution stack should support a variety of
+ forwarders, hardware forwarders (physical switches and routers)
+ as well as software forwarders. This way virtual and physical
+ forwarding domains can be seamlessly glued together.
+ * Policy driven connectivity: Connectivity should respect and
+ reflect different business
+In order to meet the desired qualities of an NFV infrastructure, the
+following components were chosen for the "Openstack - OpenDaylight
+ -" scenario:
+ * Vector Packet Processor (VPP) - a highly scalable,
+ high performance, extensible virtual forwarder
+ * OpenDaylight Controller - an extensible controller platform which
+ offers the ability to separate business logic from networking
+ constructs, supports a diverse set of network devices
+ (virtual and physical) via the "group based policy (GBP)"
+ component, and can be clustered to achieve a highly available
+ deployment.
The "Openstack - OpenDaylight -" scenario provides the capability to
realize a set of use-cases relevant to the deployment of NFV nodes instantiated
