Streamlining Communications & Applications

Location doesntmatter

Users want applications, access to data regardless of location

Trend toward centralization of apps, data Ease of management key driver

All-in-one devices gaining momentum

48% of organizations use/want to use (see next slide)

Two types of devices

Routing/switching/security/wireless/IPT/compression

App acceleration/WAFS/DHCP/DNS/Print & file servers

More attention toward robust WAN & optimization


11/29

Why a Robust WAN? Cost vs. Tradeoff

Insufficient bandwidth

Multiple WANs

No QOS/Optimization

Lack of monitoring

No benchmarking performed

No annual contract review

No standards for branch

PerformanceProblems

Decreasedproductivity

Too long totroubleshoot

Fiscalirresponsibility

No way to measuresuccess/failure

MPLS

Not a matter ofif, but when

(90%+ using/evaluating)

Urgent: Act Now

74%using/planning


15/29

Justification: MPLS

Cost savings Range is 10%-40%

Ability to integrate multiple traffictypes on one network

Any-to-any ability/DR

COS: Better manage capacity 50% dont use COS

23% use 4 or more classes

Less overhead than ATM/Frame Solid managed services available

Global coverage from singlecarrier not truly available

Costs associated withupgrade (network equipment,installation, training)

No application drivers Internet VPN still cheaper in

some cases

The Mobilized Workforce Is Here!

More than half of companies have or are planningmobility strategy.

Average anticipated 12-month growth in number ofmobile devices is 421% (median = 100%)

Of those with discrete budget, currently spending 4%-4.5% of overall IT

budget on wireless/mobility

Enterprise user populations are shifting from special-purpose (sales, logistics, onsite repair) to general

Application demand is increasing dramatically

Device requirements are more complex (multimode,security, etc.)

Bottom Lines and Recommendations

Consider key emerging WAN technologies.

Standardize products, capabilities at your distributedenterprise.

Assess the value of managed services.

Plan for expansion! The keyword here is moreapplications, bandwidth requirements, branch-office sites,

expectations from users, etc.

Leverage wirelessfixed and mobile.

Follow a formal procurement/negotiations process (no

matter how small you are).
