Our “Big Bang”

…the Internet!


Internet Is Constantly Growing

By year 2020: •  82% of the world’s IP traffic

will be video

•  There will be over 12 billion IoT connections

•  The network needs to fundamentally change

Cisco VNI Report Feb. 2016


Driven by Data Growth •  More Devices (IoT) •  More Traffic – Pervasive Video •  New 5G Enabled Applications

New Business Models •  Asset Provider (XaaS) •  Connectivity Provider •  New Partnering Arrangements

What Does the 5G Network Mean for Cisco? Keeping it very simple:

Cisco’s 5G network is a highly automated, access agnostic, super-scale platform offered to operators and enterprises. It enables new and innovative use cases either introduced securely by the operator or through enablement of third-party partners or vertical industry customers.

One key word: enablement


•  A set of verticals built on a common infrastructure •  The verticals are built on an “innovation platform” but the verticals themselves

contain the innovation •  Examples of verticals: MBB, IoT, Video/ICN, MVNO, Mobility-on-demand/ICN,

Fixed Wireless Access, Supplementary Hot Spot coverage, …

•  5G Verticals allow the use of newer mobility-friendly protocols •  They simplify the networking while removing signaling cost

•  5G uses SDN and NFV in a basic and fundamental way •  Orchestration aligns the resources and capabilities to support the vertical

Example for Core Network as it evolves to 5G What is the 5G core?

•  Definition: •  Network slicing is the ability to run multiple logical

networks as virtually independent business operations on a common physical infrastructure

•  Network slicing goes hand-in-hand with SDN and NFV

•  Comprised of three fundamental components: •  A collection of control points in the user plane that

have the ability to pivot or steer selected traffic flows on one path vs. another

•  The data-enablement of the control point so the traffic flow path selection can be controlled by subscriber database dip or policy dip

•  A Management and orchestration systems that create sand-boxes (day-0 functions) for the slices, configure them for operation (day-1) and then manage the slices (day-n)

Network Slicing 5G is all about Managing Verticals

!  MVNO Enablement •  Allow an MVNO or an Enterprise

to build a mobile service integrating VoIP and Data

!  IoT Connected Device Platform •  Allow a CDP provider (such as

Jasper) to build a connectivity platform for enterprises to reach their things

!  Enablement via tenancy •  Allow a content publisher to

optimize content delivery

!  APIs and in-band signaling •  Key for enablement

Take-aways !  We cannot work 5G in a vacuum nor can we imagine 5G as a pure “marketing construct”

•  5G use cases are completely real

!  There is a 5G emerging architecture which is becoming very visible. We can say that 5G architecture will:

•  Decouple control plane and user plane and –  hence integrate SDN and NFV in an inherent way –  Finally enable a user plane edge for a variety of applications –  Enable C-RAN

•  Support multiple very diverse use cases hence driving the need for network slicing –  Network slicing is “end-to-end” requiring SD-WAN in addition SDN and NFV

•  Support massive amounts of video hence requiring the introduction of offload, multicast-to-unicast and caching

!  The main challenge •  Introducing a graceful “from here to there” transition that emphasizes investment preservation

!  Cisco is superbly positioned for 5G through a “business enablement platform” concept •  Our business “is business”: we enable business
