"The Linktropy WAN emulator paid for itself within days when we used it to replicate a satellite link to an off-shore oil rig where a customer was reporting a performance issue. By replicating the customer's environment in our lab, we were quickly able to determine that the high latency of the link was preventing our software from fully utilizing the available bandwidth. Not only did this help us avoid a costly trip for a developer and a support engineer, but once we identified the cause of the problem, the emulator made it possible to validate the fix before sending it to the customer."
"Because actual WAN links can vary greatly, we used the Apposite Technologies Netropy 10G WAN emulator to simulate our WAN connection. Besides allowing us to throttle bandwidth, it can also inject latency, jitter, and packet loss. This allowed us to simulate the behavior of several different kinds of SAN and WAN links between our sites."
