Abstract

The Internet has become the federative network that supports a wide range of service offerings. The delivery of network services such as IP VPNs assumes the combined activation of various capabilities that include (but are not necessarily limited to) forwarding and routing (e.g., customer-specific addressing scheme management, dynamic path computation to reach a set of destination prefixes, dynamic establishment of tunnels, etc.); Quality of Service (e.g., traffic classification, marking, conditioning, and scheduling); security (e.g., filters to protect customer premises from network-originated attacks, to avoid malformed route announcements, etc.); and management (e.g., fault detection and processing).

             Software-Defined Networking: A Perspective from                  within a Service Provider Environment

Abstract

   Software-Defined Networking (SDN) has been one of the major buzz    words of the networking industry for the past couple of years.  And    yet, no clear definition of what SDN actually covers has been broadly    admitted so far.  This document aims to clarify the SDN landscape by    providing a perspective on requirements, issues, and other    considerations about SDN, as seen from within a service provider    environment.

   It is not meant to endlessly discuss what SDN truly means but rather    to suggest a functional taxonomy of the techniques that can be used    under an SDN umbrella and to elaborate on the various pending issues    the combined activation of such techniques inevitably raises.  As    such, a definition of SDN is only mentioned for the sake of    clarification.
