EXata uses network emulation and simulation to predict the behaviour and performance of networks to improve their design, operation, and management.
EXata provides a cost-effective and easy-to-use alternative to physical testbeds that typically have high equipment costs, complex setup requirements and limited scalability.
EXata uses a software virtual network (SVN) to digitally represent entire networks, including the various protocol layers, antennas, and devices. With this, the system can interoperate, at one or more protocol layers, with real radios and devices to provide hardware-in-the-loop capabilities. EXata can also be connected to systems with real applications, which run on the SVN just as they would run on real networks.
EXata mimics the functions of a real network so that it appears, interacts, and behaves like the real network. This provides an exact, reproduction of external behaviour so that the emulated system is indistinguishable from the real one.
EXata saves costs and helps in developing a net-centric system by providing an environment in which design decisions can be easily changed and their impact evaluated, before actual systems or networks are built. Additionally, customers of the net-centric system can use the emulated network to assess how their applications (such as VoIP, situational awareness, sensor data, and streaming video) will perform when the real system is built. The emulated network can also be integrated with legacy systems to both test interoperability and to train users on the next generation network.
By evaluating what works best early in the design cycle, the cost of modifying a system can be greatly reduced. This also sets realistic expectations of what the communications network will deliver, that is, it provides predictability.
