Source: NGMN – Description of Network Slicing Concept

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.

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.”
