Bandwidth constraints, network latency, packet loss, and other impairments impact the performance of applications running over the WAN. Network emulators simulate these WAN conditions to allow enterprise IT departments to assess application responsiveness prior to roll-out and optimize the end user experience for applications already deployed.
To examine how network emulators are being used by enterprise IT departments, TRAC conducted structured interviews with several Apposite customers, and summarized the findings in case studies of four users:
• Multinational insurance company managing datacenter replication and application consolidation
• International banking company building local branches far from headquarters
• Global investment firm troubleshooting problems with applications in the field
• Cloud computing infrastructure provider validating performance of applications over the internet.
As a result of these interviews, TRAC concluded that by offering visibility into the end-user experience, network emulation has become a key enabler for a wide variety of use cases, including datacenter replication, application consolidation, new technology rollouts, changes in network topology, cloud migrations, WAN optimization deployments, and many other situations. Network emulation technology helps IT staff understand bottlenecks and proactively address performance issues before they impact users, avoiding expensive troubleshooting and panic situations after deployment.
“Network emulation is an important, but still often overlooked tool for testing and optimizing application performance,”
