PRISMA specifically designed the LSU IP Server to serve the fast growing need for telecommunication testing over the IP interfaces. The evolution of recent standards for wireless and fixed networks completely relay on an “all-IP” architecture, which means that large numbers and types of different services (voice, data, multimedia, network signalling, charging info) need to concurrently run over high speed IP links.

The HW core architecture of LSU IP Server benefits from the dramatic performance improvements the x86 base systems gained with the introduction of multi-core and multi-CPU architectures. The performances of LSU IP Server’s system are proven and achieved “on field”, simply because PRISMA manages both HW and SW design processes completely and internally, continuously adapting all software packages not only to follow standards’ evolutions, but also to make the most out of top HW architectures.

Typical applications are massive monitoring over IP interfaces, real time KPI generation and collection, load&stress for Value Added Services (VAS) and Intelligent Network (IN) platforms, user tracing over time, services, port. Customized telecom applications are also available for both laboratory tests and live network monitoring.

The LSU IP Server is equipped with a dual quad-core processor and various high speed compact PCI cards, to cope with simulation and monitoring over high capacity ATM or IP trunks. QNX Neutrino, the real time operating system (RTOS) installed onto the LSU IP Server, is the same of other LSU family members. By doing so, PRISMA enables its Customers to cope with an easy migration of access and core wireless network protocols towards IP.

The specific RTOS architecture adopted by PRISMA is based on a microkernel operating system. That means that every driver, application, protocol stack, and file system run outside the kernel, in the safety of memory-protected user space. As a result, virtually any component can fail — and be automatically restarted — without affecting other components or the kernel itself.
