Abstract:
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. Additionally, existing services or capabilities like
pseudowire connectivity or global concurrent optimization can benefit
from a operational scheme that considers the application needs and
the network status. An environment that operates to meet these types
of requirement is said to have Application-Based Network Operations
(ABNO).
ABNO brings together many existing technologies for gathering
information about the resources available in a network, for
consideration of topologies and how those topologies map to
underlying network resources, for requesting path computation, and
for provisioning or reserving network resources. Thus, ABNO may be
seen as the use of a toolbox of existing components enhanced with a
few new elements. The key component within an ABNO is the Path
Computation Element (PCE), which can be used for computing paths and
is further extended to provide policy enforcement capabilities for
ABNO.
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.
