Slicing Concept

3. ITU-IMT2020 & Network Slicing
The basic concept of the Network Softwarization is “Slicing” as defined in [ITU-T Y.3011], [ITU-T Y.3012].
Slicing allows logically isolated network partitions (LINP) with a slice being considered as a unit of
programmable resources such as network, computation and storage. Considering the wide variety of
application domains to be supported by 5G or IMT-2020 network, it is necessary to extend the concept of
slicing to cover a wider range of use cases than those targeted by the current SDN/NFV technologies, and
the need to address a number of issues on how to utilize slices created on top of programmable software
defined infrastructure.

11. 5G Americas Network Slicing Management & ETSI NFV
Also mentioning 3GPP SA5 recently started new study item: “Study on management and orchestration of
network slicing for next generation network” (FS-MONETS).
The Network Slice Life Cycle Management would
typically interact with ETSI NFV MANO for these
virtualized network services and functions, as
shown in Figure 11, with an open Nsl-Ma
interface, with Nsl standing for “network slice.”
However, the PNF would be managed outside of
MANO, as well as subnetwork parts composed of
connection of PNF. This would require the
Network Slice Life Cycle Management to also
interface with a non-virtualized life cycle
management & operation environment, as shown
on Figure 11, with an open Nsl-PN interface, with
PN standing for “Physical Network.”
