               Filter-Based Packet Forwarding ECA Policy
               draft-ietf-i2rs-pkt-eca-data-model-03.txt

Abstract

   This document describes the yang data model for packet forwarding
   policy that filters received packets and forwards (or drops) the
   packets.  Filters for Layer 2, Layer 3, Layer 4, and packet-arrival
   time are linked together to support filtering for the routing layer.
   Prior to forwarding the packets out other interfaces, some of the
   fields in the packets may be modified.  (If one considers the packet
   reception an event, this packet policy is a minimalistic Event-Match
   Condition-Action policy.)  This policy controls forwarding of packets
   received by a routing device on one or more interfaces on which this
   policy is enabled.

   This data model may be used in either the configuration datastore,
   control plane datastores, or the I2RS ephemeral control plane
   datastore.

1.  Introduction

   This document describes the yang data model for packet forwarding
   policy that filters received packets and forwards (or drops) the
   packets.  Prior to forwarding the packets out other interfaces, some
   of the fields in the packets may be modified.  Filters for Layer 2,
   Layer 3, Layer-4 and packet arrival time are linked together to
   support filtering for the routing layer.

   If one considers the reception of a packet as an event, this
   minimalistic Event-Match Condition-Action policy.  Full event-match-
   condition policy can be found at
   [I-D.ietf-supa-generic-policy-data-model] (or the information model
   at [I-D.ietf-supa-generic-policy-info-model]).  This document will
   use the term packet-only ECA policy for this model utilizing the term
   "packet" in this fashion.
