Application Programming Interfaces (APIs) for Protocol Simulation

Welcome to the latest issue of GL's Newsletter providing insight into our scripting and automation capabilities for protocol simulation. The API capability has wide ranging applications for signaling and traffic simulation over IP, Wireless, TDM and Analog networks.

Application Programming Interfaces for Protocol Simulation


GL’s Signaling and Traffic Emulation test suite, commonly referred to as Message Automation and Protocol Simulation (MAPS™), provides a unique programmable, highly flexible, script based, multi-protocol, multi-interface emulation framework and makes it easy to perform cross-domain testing and transition tests to new technologies.

MAPS™ can be configured as server-side application, to enable remote controlling through multiple command-line based clients which include Python and Java. Python is supported over all protocols as a standard and Java over limited protocols.

The MAPS™ APIs allow programmatic and automated control over all MAPS™ platforms. Each MAPS™ server can receive multiple client connections and offer independent execution to each client. Likewise, a single client can connect to multiple MAPS™ servers, including servers running different protocols, permitting complex cross-protocol test cases.

The MAPS™ application provides access to signaling and traffic simulation functionalities as listed below.

  • Functional regression testing
  • Long duration, high volume performance/load testing
  • Protocol conformance testing
  • Negative testing
  • Interactive Voice Response traversal
  • Interoperability testing
  • Voice Quality testing

Wide variety of protocols are supported across TDM, VoIP, Wireless, Analog networks.
