                   IPv6 Segment Routing Header (SRH)
               draft-ietf-6man-segment-routing-header-07

Abstract

   Segment Routing (SR) allows a node to steer a packet through a
   controlled set of instructions, called segments, by prepending an SR
   header to the packet.  A segment can represent any instruction,
   topological or service-based.  SR allows to enforce a flow through
   any path (topological, or application/service based) while
   maintaining per-flow state only at the ingress node to the SR domain.

   Segment Routing can be applied to the IPv6 data plane with the
   addition of a new type of Routing Extension Header.  This draft
   describes the Segment Routing Extension Header Type and how it is
   used by SR capable nodes.
