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

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

8. 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!

15. 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.”
