Presented by : Dr. Vikram Kulkarni, Mike Yang


GL’s comprehensive Signaling and Traffic Emulation test equipment 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 such as 5G. The Core network and all its underlying entities can be accurately tested for functionalities and performance.

GL’s MAPS™ test suite can simulate 5G, 4G, 3G, 2G and IMS networks. The same versatile tool can also simulate VoIP, ED-137 and legacy networks such as SS7, ISDN, CAS etc. The application supports various test cases like single interface testing, multi-interface testing, wrap-around / isolation testing, end-to-end network testing and can create all possible call scenarios to test real-time entities within a network to perform Functional, Conformance and Load testing.

The test suite can work with GL’s specialized hardware when simulating legacy protocols such as ISDN and SS7. Or for modern protocols it can work simply by using the host PC’s network interface card to generate and receive traffic. In addition, GL’s test suite is enhanced to emulate End-to-End 5G core (5GC) Network elements such as UE+gNB, AMF, SMF, UPF, AUSF, UDM, UDR, NSSF, NRF, PCF including service-based architecture interfaces along with data and voice traffic (VoLTE support) generation.

GL’s test suite is also available as a high-density network appliance which can simulate up to 20,000 endpoints per 1U server. It can generate tens of thousands of simultaneous calls. Using a stack of servers, a larger test system with up to 200,000 simultaneous calls is achievable for enterprise testing.
