Designed explicitly to facilitate the cost-effective testing of high performance protocols and applications, dsTest® is focused on 3G/4G/5G core network service interfaces to support your network evolution testing. Select the interfaces required to accomplish your testing goals–surround a network element with client simulators that simulate client activity, provision a server emulator with the interfaces necessary to support end-to-end testing, or test agents and proxies using both client simulation and server emulation. Test your LTE, EPC, eMBMS, SMS, WLAN Offload, VoLTE and CIoT networks or gather Big Data to support the identification of patterns and that will provide new business opportunities, revenues, and efficiencies  to network operations.

  • Measure call performance and capacity
  • Verify new mobility features and standards before deployment
  • Identify performance ceilings and bottlenecks
  • Validate system scalability with easily scalable subscriber loads
  • Plan capacity
  • Interactively control and monitor real-time test configuration, event triggering, and measurement sampling

A suite of common components expedites the development cycle, allowing us to provide testing capabilities in a time frame that can assist both vendors and carriers during the development and deployment of the evolved core network. dsTest® provides a base from which new protocols and applications can be quickly developed to support new standards or custom protocols and applications. dsTest® is a software product that provides an environment that supports the goals of network function virtualization (NFV) and Software Defined Networking (SDN). Refer to the Infrastructure topics for more detailed information about dsTest® and its supporting applications, dsAnalyzer and dsClient. Browse our application bundles for the 3G, 4G, and CIoT control plane interface applications available as well as the User Data applications available for testing User Plane performance and capacity.
