PRISMA has more than 10 years of wireless protocol simulator expertise
and spends heavily in R&D to provide support for all kinds of simulation
scenarios for different network topologies, equipment vendors, traffic
quantities or traffic types (circuit switched, packet switched).
Thanks to its scalability and modularity, the LSU family can be used during
every phase of development. The hardware configuration and the installed
software can be adapted to meet the requirements and challenges of any
testing.
Software Development
Line Server Unit (LSU) is used to monitor
and decode all the protocol stacks (standard or vendor dependent) at every
interface of a GSM/GPRS/EDGE network. Software engineers can simulate
every operating condition by a powerful set of libraries for each protocol.
Scripts are written in Tcl/Tk or generated by third parties software (SDL/TTCN
editors) integrated with LSU command interface.
Integration
LSU is used as multi-interface monitor
to verify network behavior by message exchange between network elements
and to debug abnormal conditions. A set of dedicated features has been
studied following customers requests to reproduce network element failures,
faulty links, variable delays due to different network topology. Look
at Drop/Insert utility and Satellite
Delay for details.
Load & Stress
LSU is used to inject a huge traffic at every interface of the element
under test in order to verify its robustness. Simulation results are analyzed
in real-time or by post-processing. The scalability of LSU allows to increase
the number of lines and processing power from a few lines up to hundreds
of lines at wire-speed running tests in parallel over one or more network
elements under stress.
Up to now the LSU is the most powerful system for load & stress
of EDGE network elements able to simulate thousands of mobile
phone-originating EDGE sessions over hundreds of lines, with
exceptional performance.
