 Problem Description
 -------------------
 
+Telco ecosystem's movement toward cloud domain results in Network Function Virtualization
+that is discussed and specified in ETSI NFV. This movement opens up many green field
+areas which are full of potentials of growth in both business and technology. This new
+NFV domain brings new business opportunities and new market segments as well as emerging
+technologies that are exploratory and experimental in nature, especially in NFV networking.

 It is often stated that NFV imposes additional requirements on the networking
 architecture and feature set of the underlying NFVI beyond those of data center
 networking. For instance, the NFVI needs to establish and manage connectivity
