Networks today integrate multiple technologies allowing network infrastructure to deliver a variety of services to support the different characteristics and demands of applications. There is an increasing demand to make the network responsive to service requests issued directly from the application layer. This differs from the established model where services in the network are delivered in response to management commands driven by a human user.

    A PCE-Based Architecture for Application-Based Network Operations


   Services such as content distribution, distributed databases, or    inter-data center connectivity place a set of new requirements on the    operation of networks.  They need on-demand and application-specific    reservation of network connectivity, reliability, and resources (such    as bandwidth) in a variety of network applications (such as point-to-    point connectivity, network virtualization, or mobile back-haul) and    in a range of network technologies from packet (IP/MPLS) down to    optical.  An environment that operates to meet these types of    requirements is said to have Application-Based Network Operations    (ABNO).  ABNO brings together many existing technologies and may be    seen as the use of a toolbox of existing components enhanced with a    few new elements.

   This document describes an architecture and framework for ABNO,    showing how these components fit together.  It provides a cookbook of    existing technologies to satisfy the architecture and meet the needs    of the applications.
