Abstract:
The purpose of a Network Policy System is to manage and control a
network as a whole. To achieve this purpose, network operators need
to control the behavior of the individual entities that comprise the
network, and this control needs to be harmonized across multiple
entities. For example, to control the access to a network, the
operator must control the behavior at all of network elements at the
edge of the network, and must apply consistent policies at those
elements.
Network Services are provided by network operators to their customers
using the resources of the network. To effectively control a
network, the operator must have knowledge of network services
supported by the network, as well as knowledge of the network
resource utilization and the capabilities of each network entity.
Control of the network to deliver the network services will involve
applying policy at individual network entities and across the whole
network, as well as controlling and allocating the resources within
the network.
This document describes a common framework and common core YANG data
model for network policies. The framework can be applied to deliver
various different network services by controlling the policies that
enable features such as Constraint-based Routing, Network QoS,
Traffic engineering, network management, etc. In future, the core
data model could be augmented by additional YANG data modules
modeling and configuring policy-related protocols and functions. The
policy data model described in this document provides common building
blocks for such extensions.
