             An Information Model for Basic Network Policy
                   draft-hares-i2rs-bnp-info-model-00

Abstract

   This document contains three information Models: Basic Network Policy
   (BNP IM).  ACLs do not provide all the policy support required by
   BGP, Policy Based Routing (PBR), SFC Topology Information Model (SF-
   Topo IM), Service Forwarding Chaing IM (SFC IM), and and flow
   specification filtering.  The BNP IM has the following top-down
   levels of Policy Hierarchy: Policy Set, Policy Group, Policy Rule,
   and conditional actions within the policy rule (conditional match and
   Actions).  These can be used in PBR-RIB or BGP to provide an ordered
   set of policy rules grouped with a Policy Group via operators (AND,
   OR, etc.) and ordered by a combination of priority and precedence.
   The Policy is an ordered set of Policy Groups.

   The BNP IM is based on the concept of an extensible information model
   for representing policies.  This concept is also found in the Policy
   Core Information Model (PCIM) (RFC3060) and the Quality of Service
   (QoS) Policy Information Model (QPIM)(RFC3644) and policy based
   routing.

1.  Introduction

   The Interface to the Routing System (I2RS) provides read and write
   access to the information and state within the routing process within
   routing elements.  The I2RS client interacts with one or more I2RS
   agents to collect information from network routing systems.
