The Enterprise as Network Needs…


Simplification

Abstraction and Virtualization

Automation

Centralized Management

The enterprise

is coming to be

defined by the

web of users,

sites, devices,

and services it

connects via its

network.

Enterprises

Need

6

Data Center Pressure Still Rising

Rising east/west stream

count

High east/west hop counts

Rising traffic volume,

bandwidth per stream

Denser packing of

servers…and now containers

Calls for microservices

architecture and

microsegmentation will

exacerbate

= 1 Transaction


7

Denser, Flatter, Smarter, and Policy Driven

Mesh and Leaf/Spine to drop hop

counts….AND

Use policy to group nodes and

control flows, segment traffic

Autoprovision new gear as added,

autoconfigure nodes as attached

Some extend fabrics to campus,

WAN

NFV coming; JIT float in new

function

24% generally

Overall, deployments are

SDN Rising Fast As ACI and NSX Knowledge Spreads

Campus Challenges: More Everything, Everywhere

Mobility

Demanding more bandwidth

Devices


Video/Rich Media


• Client-Server

Computing

• Stationary 1 GB

access as primary

• WLAN as an adjunct

• Over-subscribed

backbones

Yet Data Networks

Are Designed For:

• Support hoteling,

roaming, flexible

work teams,

huddles

• Light up new

branches quickly,

easily, cheaply

802.11ac Continues Powering Rise of Wireless-First


The 802.11n

jump

The beginning

Of 802.11ac

Only 30% have a formal policy in place to

determine capacity needs for wireless rollouts.

15

Speed YES! But Also Management and Control


Look for management integration into rest of

campus network

Unified policy environment, wired and wireless

SDN extended to WLAN

Look for resilient configuration, high densities,

linkage to EMM

Integration with WAN also attractive…

16

Today’s WAN: Either-Or for Primary Link Links


Use either MPLS

link or Internet

VPN as primary

Where a branch

has multiple links,

most only have

failover—only one

link in use at a

time.

Failover is not fast,

sessions all die.

SDWAN: More than Hybrid Links


Abstract WAN

architectures from

links

Many links look like

one pool of

bandwidth

Many virtual WANs

overlaid on

available

bandwidth

Mix and match

topologies based

on traffic needs

19

SDWAN Aims to Simplify Management

Policy controls everything

Not node-by-node

configuration—configure the

WAN as a whole

Security – will the packets be

allowed to flow, and if so, with

what security layered on

Topology – what paths packets

will follow

Performance – everything from

FEC and prioritization to

compression is possible

Recommendations

The Enterprise is coming to be defined by the web of users,

sites, devices, and services it connects via its network

Set your sights on automation, policy-driven control, and

centralized management

Unify management tools where you can…

Even though you’ll want separate domains of management for DC, campus, WAN

Look in your 3—5 year future and plan as needed for DC

fabric, SDN, SDWAN, WAN-CX, and fast, dense WiFi

Think about security in every layer
