5G … Prepare for a world where everything Computes & is Connected

Technology will be

embedded everywhere

Everything

will be understood

Everyone & everything

will be connected

3

Compute capabilities are changing how networks are build Blurring the boundaries between network and service infrastructure

4

From a hierarchical network, where

functions are placed along the traffic path

To a flattened network, where functions are

optimally placed and traffic is steered towards

the most optimally placed service functions

with low latency requirements are

driving 5G Network design

What is Network Functions Virtualization (NFV)?it is the ability to provide network functions on industry standard platforms

Evolution of IT virtualization techniques for core network functions

• Use standard servers and storage

• Reduced equipment costs

• Faster time to market

• Resource sharing

• Targeted service introduction

Implement network functions in SW

• It can be moved to, or instantiated in, various locations in the network as required, without the need to install new equipment!

Classic network appliance approach

Carrier-grade NAT

BRAS Radio accessnetwork nodes

• Fragmented non-commodity hardware

• Physical install per appliance per site

• Hardware development large barrier to entry for new vendors, constraining innovation and competition

NETWORK SLICING SYSTEM ARCHITECTURE (E2E NETWORK SLICING)

Network Slicing Management & ETSI NFV

Also mentioning 3GPP SA5 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.”
