           Dissemination of Flow Specification Rules for IPv6
                     draft-ietf-idr-flow-spec-v6-10

Abstract

   Dissemination of Flow Specification Rules [I-D.ietf-idr-rfc5575bis]
   provides a protocol extension for propagation of traffic flow
   information for the purpose of rate limiting or filtering.  The
   [I-D.ietf-idr-rfc5575bis] specifies those extensions for IPv4
   protocol data packets only.

   This specification extends [I-D.ietf-idr-rfc5575bis] and defines
   changes to the original document in order to make it also usable and
   applicable to IPv6 data packets.

1.  Introduction

   The growing amount of IPv6 traffic in private and public networks
   requires the extension of tools used in the IPv4 only networks to be
   also capable of supporting IPv6 data packets.

   In this document authors analyze the differences of IPv6 [RFC2460]
   flows description from those of traditional IPv4 packets and propose
   subset of new encoding formats to enable Dissemination of Flow
