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.
