+## Description ##
+A SP wants to offer a service to corporations consisting of a VPN service with 
+access to different types of endpoints (other corporate sites, Internet or 
+public cloud) where each corporation can insert a custom chain of VNFs in the 
+middle.
+
+Selected traffic from corporates can reach an NFV datacenter. Once in the 
+datacenter, the corporation can select which chains to be used for each traffic
+flow (i.e. classified) depending on e.g. the source and destination of the 
+traffic. For instance:
+
+* FROM Corporate site TO Amazon: chain A
+* FROM Corporate site TO Internet: chain B
+* FROM Corporate site TO Corporate site: chain C 
+* FROM a VPN connection from an employee TO Internet: chain D
+* FROM a VPN connection from an employee TO Corporate Site: chain C
