     ISIS Extension to Support Network Slicing over IPv6 Dataplane
              draft-peng-lsr-isis-network-slicing-srv6-00

Abstract

   [I-D.peng-teas-network-slicing] defines an unified TN-slice
   identifier, i.e., AII(administrative instance identifier) and related
   processing combined with Segment Routing technology, for the purpose
   of unified identification of topology, computing, storage resources,
   unified partition of L2 and L3 link resources, unified basis of
   underlay path selection within or between domains, and unified flow
   steering rule with SR policy color scheme.  This document describes
   the ISIS extensions required to support Packet Network Slicing over
   IPv6 dataplane.

1.  Introduction

   For a packet network, network slicing requires the underlying network
   to support partitioning of the network resources to provide the
   client with dedicated (private) networking, computing, and storage
   resources drawn from a shared pool.  [I-D.peng-teas-network-slicing]
   defines an unified TN-slice identifier, i.e., AII(administrative
   instance identifier) and related processing combined with Segment
   Routing technology, for the purpose of unified identification of
   topology, computing, storage resources, unified partition of L2 and
   L3 link resources, unified basis of underlay path selection within or
   between domains, and unified flow steering rule with SR policy color
   scheme.
