2. What is Driving Change in the Branch?
AGENDA

3. Increasing Demands on the Branch Network
RISK | ASSET MANAGEMENT | COMPLEXITY
Proliferation of Intelligent
Devices
More people and more devices, many
mobile, are on the network
The Need for a Multi-
functional Network
Collaboration requires voice, video, and
data simultaneously
Additional Complexity
with Shrinking Staff
Need for rapid provisioning and real-
time services

4. Mobility and Cloud are Changing the Business Landscape
New Digital Experiences Make the Network More Relevant

No Probes
• Deep packet inspection
• Passive monitoring for voice, video,
critical apps and best-effort apps
• No additional hardware (and
included in IOS-AX license)
Business-Aligned Privacy
Enforcement
• No need for complex IP and port
ACLs
• See inside HTTP flows to identify
specific Cloud applications
Smart Capacity

Network Challenges
• Customer’s own content already cached in the
Akamai Intelligent Platform
• Last mile access may still be an issue
• Users access their own and 3rd party content from
the branch
Akamai Connect Solution
• Cache previously “non-cacheable” Internet content
inside the branch
• Utilizes the breadth and scale of the Akamai
Intelligent Platform
• Automatically takes advantages of changes in the
Akamai Intelligent Platform
