Comprehensive emulation of large wired and wireless networks, to predict behaviour and performance

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.

EXata enables users to:

  • Develop emulation or simulation models for new networking technologies
  • Design new network technologies
  • Design new communications protocol models using the OSI-style architecture of EXata protocol stack
  • Design wireless networks of real world size (EXata can be run on multi-core processor computers to evaluate large wireless networks of hundred and thousands of devices)
  • Perform what-if analyses: users can design a network, and then run batch experiments to test network performance when parameters, such as routing protocols, timers, and transmission power, are varied.
  • Connect real networks, applications, and devices to the EXata emulated network
  • See real applications run on emulated networks: EXata can run real applications, such as VoIP, internet browsers, and streaming video, on emulated networks as if they were running on real networks
  • Train with the network before it is ready to be deployed: EXata makes it possible to conduct training and operations with networks and devices that are still being designed
  • Analyse and manage EXata virtual networks with popular, industry-standard, tools
  • Snoop on packets: EXata has a packet sniffer interface that enables third-party tools like Wireshark and Microsoft Network Monitor to snoop/capture traffic from any device in EXata and analyse it. Letting users debug and troubleshoot network problems.
  • Manage an emulated network: EXata comes with a SNMP Agent, which enables users to use standard SNMP managers to view, monitor and control emulated networks in EXata just like managing real networks
