4. IETF RFC 7149
 Internet Engineering Task Force RFC 7149
 March 2014
 Software-Defined Networking: A Perspective from within a
Service Provider Environment
 Aims to clarify the SDN landscape by providing a perspective
on requirements, issues, and other considerations about SDN
 Not meant to endlessly discuss what SDN truly means but
rather to suggest a functional taxonomy of the techniques

5. IETF RFC 7149 (Contd.)
 The separation of the forwarding and control
planes (beyond implementation considerations)
has almost become a gimmick
 Technically, most of the current router
implementations have been assuming this
separation for decades:
 Routing processes (such as IGP and BGP route
computation) have often been software based, while
forwarding capabilities are usually implemented in
hardware

 Flexibility:
 E.g., ability to accommodate short duration extra
bandwidth requirements
 Techniques for the dynamic discovery of
network topology, devices, and capabilities
 Dynamic feedback mechanisms
