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

Explosion of connected devices
(IoT), the ever increasing use of
video and interactive applications
with low latency requirements are
driving 5G Network design
IoT and MEC are driving a highly distributed network design with compute capabilities that are as pervasive as the connectivity

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

CDN Session border
controller
WANacceleration
DPI Firewall
Carrier-grade NAT
Tester/QoEmonitor
SGSN/GGSN
PErouter
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 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.”
