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

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

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).
