Abstract :
This paper outlines a comprehensive model to
increase system efficiency, preserve network
bandwidth, monitor incoming and outgoing packets,
ens
ure the security of confidential files and reduce
power wastage in an organization. This model
illustrates the use and potential application of a
Network Analysis Tool (NAT) in a multi
-
computer
set
-
up of any scale. The model is designed to run in
the backg
round and not hamper any currently
executing applications, while using minimum system
resources. It was developed as open source software,
using VB.Net, with a view to overcoming limitations
of legacy systems and financial restrictions in small
-
to mid
-
leve
l organizations like businesses and
educational institutes. It is fully
-
customizable and
serves as a simple and open
-
source alternative to
existing software. The NAT relies on simple client
-
server architecture and uses remote access to monitor
and maintain
the computers on a network, for
example logging off a user or shutting down a
computer after a certain "idle" time, enabling and
disabling applications, troubleshooting and so on.
The NAT was tested in a laboratory and resultant
data is presented, along w
ith the results of a survey
that was conducted among users.
