Agenda

• What’s the Problem• This Thing Called NFV• Enterprise NFV Building Blocks• Platforms for Enterprise NFV

What’s The Problem

The Current Enterprise Branch Landscape

Multiple DevicesRouters, Appliances, Servers

Costly to OperateUpgrades, refresh cycles,

site visits

Difficult to ManageDevice integration and

operation

Horseman of the branch apocalypse

Now think of deploying an additional serviceFirst, the integration complexity

Next, the logistical challenge …Shipping equipmentTruck roll to install equipment

So why is this different than virtualization done at the Data Center?

Implementing VirtualizationData Center and Branch

Focus on virtualization has been in the cloud and DC where between management console, VMs and hypervisors:

• Near infinite bandwidth • Near zero latency • Straight IP

Over the WAN this is not the same:• WAN BW is not infinite• WAN latency is not sub millisecond• WANs have tunneling, encryption, and labeling• Management of the hypervisor can be dependent

on a VM and its stability

• Packet from the same flow can be spread across many different CPU pools

• Packet from the same flow use same CPU pool

• Two, Three or more VMs may process all packets of the same flow PKT

What’s this NFV thing all about

What NFV Can Do For You

Gives you flexible deployment options

Simplify day to day operations

Quickly roll out new services and locationsSimple and easy

to design, provision, manage the trusted

services that are critical to your business

Why Virtualization for the Network?

Lower operating costsAND

76% of companies planning to or investing in Big Data

80% of organizations will primarily use SaaS by 2018
