Suffice it to say that while the telecommunication requirements
of defense forces might have changed over the years, the basic
service definitions are in fact well defined and have remained
constant. The network infrastructure and its supporting services
are an essential part of the organizational strategy, and as
such need to support the military equivalent of business processes.
The first priority is connectivity, or bandwidth. A robust
NCW communication infrastructure must be able to support and
transport the vast amounts of voice, data and video-based services
to enable decision makers to gain a complete picture of the
battlefield in real time.
Second, there is redundancy. In the civilian sector, a network
failure may cause inconvenience and monetary loss in most cases.
In the case of the military and defense corps, the slightest
system down time may translate into a national security threat
- an intolerable reality. The industry benchmark of “five
nines” for network reliability, which is usually acceptable
for non-military service providers, is not a valid option for
an organization which demands “always up and running”
systems.
Flexibility is another necessity, as the information transmitted
must keep up with the rapidly changing battle realities and
maneuvering forces. One may argue that flexibility is also important
in civilian telecom. However, no operator has ever prepared
itself for a scenario in which an entire city moves from one
side of the country to the other. The level of flexibility demanded
in the defense sector is significantly higher.
Another important aspect is “cost effectiveness.”
The task of building a converged infrastructure for communication
applications is not a new practice. The first converged infrastructures
were based on several distinct platforms. In recent years, these
different platforms have evolved into a new architecture based
on IP/MPLS protocols. The idea of building a converged infrastructure
has arisen from the capital expenses fiascos of building multiple
infrastructures per service and then struggling to keep them
alive and working together, in order to utilize them for newer,
more advanced services.
The foundation lies in the fact that an NCW communication infrastructure
must scale in two major dimensions: volume (amount of users,
bases, bandwidth and so on) and technology (allowing the phase-in
and out of new and legacy technologies). Scalability is key
when ramping up a communications system while moving from routine
operations to wartime preparedness.
