groupnone stateactive pages14 rev03 expires2026-06-25 canonicalhttps://datatracker.ietf.org/doc/draft-gong-spring-hierarchical-slice-solution/

This document describes a Segment Routing based solution for two- level hierarchical IETF network slices. Level-1 network slice is realized by associating Flex-Algo with dedicated sub-interfaces, and level-2 network slice is realized by using SR Policy with additional NRP-ID on data plane.
