1. Introduction
[I-D.ietf-teas-ietf-network-slice-definition] defines the concept of
IETF network slices that provide connectivity coupled with a set of
specific commitments of network resources between a number of
endpoints over a shared network infrastructure and describes a number
of use-cases benefiting from network slicing including:
o 5G network slicing
o Network wholesale services
o Network sharing among operators
o NFV connectivity and Data Center Interconnect
In the document also clearly stated services that might benefit from
the network slices include but not limited to the above use-cases.
