Developing Solutions was recently acquired by Mobileum. Developing Solutions is focused on protocol development, test, and traffic analysis. We have developed dsTest, a software platform for the rapid deployment of protocols stacks, intended for performance and functional test. This platform is designed to take advantage of the latest processor technology, in order to provide very high performance and capacity products, which scale cost effectively to over 200+ million subscribers and/or 1.2 million transactions per second. With our dsTest product, we have solutions for testing/emulating subscriber management, policy and charging, Diameter Routing, VoWiFi/WLAN Offload, SMS, IMS, eMBMS, and M2M/MTC/CIoT nodes with the 3G/4G/5G mobile packet core. We provide customized variants of standard protocols, or full custom protocol/applications. We also offer network traffic capture, analysis and automated dsTest test case configuration with our dsAnalyzer tool.
