EXata makes it possible to exercise both equipment-in-the-loop
and humans-in-the-loop using “software virtual networks”
(SVN’s). Much like the flight simulators used to train
pilots, SVN’s provide a robust platform to conduct network
testing and operations training with an unprecedented
level of realism. SVN’s are capable of interfacing with
actual networks, running actual applications, in real
time - thus enabling the evaluation of new technologies
rapidly and at much lower cost than previously possible.
The technology advancement that enables EXata to deliver
this realism is true or real-time emulation - an exact
digital replication of a physical wireless network.
Any hardware, software, or human user connected to an
EXata SVN is not able to discern a difference between
real networks and components and their virtual (emulated)
replacements.
What Makes Real-Time Emulation Possible?
EXata breaks new ground in speed and fidelity compared
to the current class of simulation and emulation systems.
The underlying computer code, known as the kernel, is
built with patent-pending computationally efficient
code that dramatically increases speed and accuracy
on any computing platform. EXata is the only emulation
system that can use advanced parallel processing to
digitally represent every layer in the wireless communications
protocol “stack.” EXata also produces superior predictability
of actual performance. As a result, many more potential
solutions can be tested and evaluated, allowing engineers
to solve more problems with fewer technical compromises.
Software Virtual Networks Displace
Costly Testbeds
Network testing is complex and costly because scientifically
rigorous studies require repeated trials. Being able
to start and stop trials - as well as pause and modify
parameters on the fly - is necessary to efficiently
conduct such experiments. EXata SVN’s displace the traditional
model of physical testbed evaluation by leveraging the
flexibility and low cost of simulation to produce the
highly accurate, highly detailed results of a testbed.
Furthermore, the EXata SVN can stay in service throughout
the lifecycle of the system to provide increasing levels
of detail and realism as the project demands.
EXata Product Family
The EXata product family consists of EXata and a collection
of add-on libraries that model various communication
protocols. The power of additional processors can be
added with a license upgrade. A feature-rich visual
development environment allows users to set up models
quickly and then run models that present real-time statistics
and helpful packet-level debugging insight.
EXata provides out-of-the-box support for quad-core
processor systems. It is possible to achieve real-time
emulation with the base EXata product. For additional
speed-up and scalability through parallel execution,
users can upgrade EXata to run on multiples of four
processors.
