 Market Observations
The Way Businesses Use WAN Infrastructures Is Changing!
 Consolidation, Centralization & Virtualization
    – Complete desktop virtualization (virtual desktop infrastructure)
    – Server based computing (application centralization)
    – Webified applications
    – Branch office server replacement through virtualization
 Bandwidth cost, availability, throughput & latency challenges
    – Satellite availability and Cost
    – International links
    – Remote, roaming & isolated users
    – Meshed networks (MPLS), any to any traffic, Monitoring and Control
 The distance between the user and the application is growing
 WAN infrastructure & cost directly impacts the ROI-TCO of other IT projects

                                                 3
Proximity Gap Analysis
The key causes of WAN application performance issues:
   DATA CENTER                                             BRANCH OFFICE




   Not enough bandwidth capacity             Transport & application
                                               protocol chattiness


   High latency & / or packet loss       Lack of visibility & control of
                                                  WAN traffic


  Without solving all four challenges, user experience will not improve

512Kbps Satellite Link with 500ms Latency




                       15
Satellite Challenge in Iraq – USMC
Challenge - USMC was trying to run COOP and DR
 over a 1.5Mbps satellite link with 1000ms of
 latency.
  – 100kbps of effective throughput
  – Mission could not be accomplished
Solution - Implement TCP Acceleration and Caching
  – Latency Mitigated
  – Effective bandwidth increased to 6Mbps.
Mission Accomplished


                            16
 Latency Challenge - International
Challenge – Insurance company trying to run RDP to process
  documents over a 2Mbps link with 200ms of latency between US
  and India.
   – It would take 8 remote users in India over 60 seconds to scroll
     through a 10 page PDF document.
   – Significant loss of productivity caused by waiting for PDF
     document pages to load.

Solution - Implement TCP Acceleration and Caching
   – Latency Mitigated
   – Page scrolling time reduced to 5 seconds per PDF document
   – Amount of users sharing the link was doubled

Mission Accomplished
