Apposite WAN Emulators

Apposite’s award-winning WAN emulators simulate the bandwidth, latency, and loss of wide-area networks to test the performance of applications in the lab. Apposite’s WAN emulation appliances are affordable and easy to use, while offering unmatched levels of precision and performance.

Key Features

  • Profile live networks and import into WAN simulation
  • Replay capture files as background traffic
  • Change WAN impairments and view results in real time
  • Configure via browser or automate with CLI

Testing provides critical insights into application performance:


Bulk data transfers such as storage replication and file transfer need to fully utilize the available bandwidth to complete quickly.


Users depend on responsive interaction with transaction-based applications such as web and database systems.


Voice, video, and other collaboration tools need to provide a high quality experience for teams to work efficiently between locations.
