three commonly used simulators web, ios & network simulators
TRANSCRIPT
A number of simulation systems are being developed, every day. Needless to
mention their applications and uses! For example, flight simulators are used for
training pilots to be able to respond quickly in critical flight situations. They are
equipped with features that are aimed for pilots to think that they are actually
driving a real plane; or the prevailing flight situation is actually a real one.
Similarly, military simulation systems make the troops believe that they are
interfacing with real opponents in a real battle.
Today, a number of
simulators have
come up related to
testing and verifying
the networking
applications and day-
to-day functions. We
are highlighting only
three of the most
important simulators
here.
One of the main simulators that is used today is the Web simulator. This is used to
simulate a real web server. It is mainly used for the developers of web based
applications. Actually, most of the projects that are based on this simulator are
aimed at coming up with testing the scalability of the web based applications that is
capable of managing thousands of web services. The main essence of having the
simulator is to make sure that all the necessary requirements of the web application
have been met. There are numerous features that come with this simulator.
Another important simulator that
is commonly used today is the
Cisco IOS Simulator. This is one
of the most popular simulators that
are available today. It comes with
a number of features that have
been incorporated for purposes of
replicating a real IOS. The IOS is
the operating system for Cisco.
IOS simulator works on Cisco
devices which include the 3640,
7206, 6260, 6500 and works
seamlessly with, Cisco Prime
Infrastructure, GSR manager,
Cisco works 2000 and other
network management applications.
The simulator can replicate
thousands of Cisco devices and
then Telnet/SSH in to those
devices.
Another simulator that is also
used on a wide scale is the
Network Simulator. It boasts of
many features that make it
suitable for simulating a real
network. The network simulator
is actually software that is
mainly used for predicting the
behaviour and performance of
any network applications. Under
normal circumstances, it is
difficult to analyse computer
networks due to their complex
nature. Therefore, network
simulators are used to study their
behaviour. It can simulate
thousands of networking devices
to try various scenarios to make
sure applications manage those
correctly.
