  Network Slicing Use Cases: Network Customization and Differentiated
                                Services
                      draft-netslices-usecases-01

Abstract

   Network Slicing is meant to enable creating (end-to-end) partitioned
   network infrastructure which may include the user equipment, access/
   core transport networks, edge and central data center resources to
   provide differentiated connectivity behaviors to fulfill the
   requirements of distinct services, applications and customers.  In
   this context, connectivity is not restricted to differentiated
   forwarding capabilities but it covers also advanced service functions
   that will be invoked when transferring data within a given domain.

   The purpose of this document is to focus on use cases that benefit
   from the usefulness of network slicing.
