The business environment is changing
Increasing dependence on
business applications
Increasing consolidation of IT
 Lower costs & easier to manage
 Guaranteed data protection
Increasing distribution of organizations
 67% of employees work in a location
other than the headquarters
 Globalization – global clients, global
projects, global offices

The Riverbed Optimization System (RiOS)
12
The three root causes of poor wide-area application
performance
Not enough bandwidth
Transport protocol chattiness
Application protocol inefficiencies
If you don’t solve all three, users won’t see performance benefits.

RiOS is an integrated approach
The Riverbed Optimization System
Data Streamlining
• Eliminate redundant bytes from transfers
Transport Streamlining
• Eliminate transport protocol inefficiencies
Application Streamlining
• Optimize application WAN performance
Management Streamlining
• Enable transparent deployment & central management

Simplicity is key for a successful WDS deployment
Simple to deploy
“I was very surprised by how simple the deployment was. I expected a complex
integration, but it only required that I give each appliance an IP address. It was only a
matter of minutes before I had the boxes up and running.”
- Senior Systems Engineer, Investor AB
Immediate impact across applications
“We were quite surprised when one day our backup process took 25% of its usual time,
because we were busy analyzing the effects of Riverbed Steelhead appliances on our FTP
transfers. We made no changes to our software – the Steelhead appliances just started
working right away.”
- Director of IT, Mercury Interactive
