High-Tech Armor for Network-Centric Warfare
SNT’s breakthrough wireless network development
technology enables rapid development of threat
prevention and interrupt/disrupt defense capabilities.
As the breakneck pace of wireless networking
deployment extends into the national defense and
security frontier, a breakthrough technology is
enabling network engineers and military operations
planners to evaluate new components and deployment
strategies to make net-centric operations more
predictable and secure against external threats.
“Software virtual networks” (SVNs) dramatically
reduce the cost and cycle time for evaluating
new wireless network technologies — orders of
magnitude below what has been possible until now.
Challenges in Upgrading Existing
Communications Networks
Existing tactical communications networks, such
as the Tactical Data Information Link (TADIL)
J in use today by the U.S. armed services and
the National Security Agency (NSA) as part of
the NATO Link 16 system, lack the modern capability
to route specific data packets to specific addresses.
TADIL J only supports broadcasting, making it
susceptible to malicious network-centric threats
such as jamming and eavesdropping.
In the emerging Global Information Grid (GIG),
packet-based, routable wireless networks based
on the 802.11e standard enable new capabilities
to integrate voice, data, and video information
in real time on the battlefield. The vision of
GIG as a seamless, secure, and interconnected
information environment is supported by the NSA’s
Information Assurance (IA) security services specifications.
IA augments commercial wireless technologies to
meet Department of Defense mission-critical requirements.
The advantages of adding IA to a proven commercial
technology such as 802.11e instead of a less open,
narrowly deployed technology like Link 16 are
lower cost and faster deployment. Since commercial
technologies are built on open standards, effective
IA requires continuous assessment of encryption
strength and susceptibility to malicious threats,
attacks, and penetrations such as passive eavesdropping,
denial-of-service, jamming, wormholes, and rushing
attacks. It also requires detailed understanding
of security in every layer of the wireless protocol
stack: physical, media access control, network
routing, transport/transmission, and applications.
The ongoing security challenge can be studied
quite well with high fidelity simulation technology,
such as QualNet, as well as emulation software
such as EXata. QualNet and EXata get engineers
to the answers faster by allowing them to test
and evaluate emulated network components and systems
in SVNs instead of costly and time-consuming physical
testbeds built with prototype components and technologies.
Software Virtual Networks Replace
Costly Testbeds
EXata uses a technology called true emulation
to create SVNs, exact digital or “virtual” duplicates
of live physical components in complex networks.
Any hardware, software, or human user connected
to this emulated network is not able to tell the
difference between a real network component and
its emulated replacement.
SVNs created in EXata deliver two substantial
advantages over physical testbeds. First, emulation
enables engineers to test and evaluate potential
inter-operation solutions much earlier in the
design process, at a fraction of the cost of physical
testbeds. Emulation reduces cost by minimizing
prototype iterations through the development cycle.
It also eliminates the need to acquire large physical
spaces within which to construct testbeds; you
can’t test routing protocols or connectivity issues
if all the radios are in the same room.
Second, EXata produces better predictability
of actual performance because of engineers can
test solutions against all potential environmental
effects. As a result, many more potential solutions
can be evaluated and more problems can be solved
with fewer technical compromises.
Maintaining Technology Superiority
— Faster and Less Costly
Using QualNet and EXata throughout the design
and development process will lead to faster and
better solutions to the ongoing need to maintain
high security and availability in the face of
combatant threats and advancing technology.
SNT’s technology will support the stability and
security of the free world and maintain America’s
preeminence as the world’s military superpower. |
