Abstract:

   BGP Flow Specification (Flowspec) provides a mechanism to distribute
   traffic flow specifications and the forwarding actions to be
   performed to the specific traffic flows.  A set of Flowspec
   components are defined to specify the matching criteria that can be
   applied to the packet, and a set of BGP extended communities are
   defined to encode the actions a routing system can take on a packet
   which matches the flow specification.

   An IETF Network Slice enables connectivity between a set of Service
   Demarcation Points (SDPs) with specific Service Level Objectives
   (SLOs) and Service Level Expectations (SLEs) over a common underlay
   network.  To meet the connectivity and performance requirements of
   network slice services, network slice service traffic may need to be
   mapped to a corresponding Network Resource Partition (NRP).  The edge
   nodes of the NRP needs to identify the traffic flows of specific
   connectivity constructs of network slices, and steer the matched
   traffic into the corresponding NRP, or a specific path within the
   corresponding NRP.

   BGP Flowspec can be used to distribute the matching criteria and the
   forwarding actions to be preformed on network slice service traffic.
   The existing Flowspec components can be reused for the matching of
   network slice services flows at the edge of an NRP.  New components
   and traffic action may need to be defined for steering network slice
   service flows into the corresponding NRP.  This document defines the
   extensions to BGP Flowspec for IETF network slice traffic steering
   (NS-TS).
