The SoftPerfect Connection Emulator (SCE) software is aimed for network application developers, system administrators and network engineers. Software developers creating network-enabled applications, especially those time-critical such as VoIP software or real time protocols, need to test their products thoroughly in a range of environments. Apparently most applications work well on broadband connections, but what if you need to test your application on a low-speed communication link such as ISDN or dial-up?

This is where SCE comes in handy. It imitates a network connection with a low bandwidth limit, latency and losses. Using SCE you can test how well your application performs on a slow or long distance connection to ensure the quality of the product being developed. SCE runs on any PC with Windows XP or higher, allowing you to selectively apply bandwidth limits, introduce random or fixed delays on data flows, and simulate packet loss to mimic a low-grade communication channel.
