| BBN networking development methods includes M&S tools and emulation
techniques that provide low to high levels of fidelity for development
and validation of networking algorithms, protocols and runtime software.
Tools include industry available environments including OPNET and a BBN
developed K-Node network emulation environment.
Both environments are extensively used to validate software prior
to integration on target hardware. The OPNET environment allows
us to rapidly develop behavioral models to facilitate validation
of the design. Once satisfied that the approach is sound, "shared code"
models are then developed that allow a much higher level of fidelity
to be used to validate against the the same operating scenarios. This
"shared code" is then reused by re-compiling for the "real-time" BBN K-Node
environment. The result is that we are capable of running, testing and
refining our applications without the need of scarce radio hardware resources.
For the MILCOM paper, we will further describe the how BBN K-Node network
emulator can run a high-fidelity emulation of JTRS Common Network
Services and further permit experimentation with link and network
parameters in plausible military scenarios with realistic user and
network overhead traffic flows. Our current experimental results
show that link data rates planned for LandWarNet and the Airborne
Network can support useful user traffic flows approaching 1Mbit/sec
under conditions of battlefield mobility.
