          Abstract 
           
           
          This document describes how to build network slice using the 
          Segment Routing based technology. It explains how the existing  
          building blocks specified for the Segment Routing can be used for 
          this purpose.

          1  Introduction 
           
          As more and more Service Providers and Enterprises operate a 
          single network infrastructure to support an ever-increasing 
          number of services, the ability to custom fit transport to 
          application needs is critically important. This includes 
          creating network slices with different characteristics can 
          coexist on top of the shared network infrastructure.  
           
          Network Slicing is meant to create (end-to-end) partitioned 
          network infrastructure that can be used to provide 
          differentiated connectivity behaviors to fulfill the
