The packet analysis as a helpful way of network monitoring

By Milica D. Djekic

The internet packets are the sets of information being created and transmitted to carry on a
message through the network’s communications. These packets may consist of many bytes and
they would also get some details regarding source and destination data as well as much more
useful information describing the packet.

One of the most convenient tools being used to a packet analysis today is a Wireshark offering
many good functions and capabilities. This tool could get used for a hacking as well as defense
purposes. It takes only few days of training to learn how to take advantage over that application.
Through this article, we intend to discuss how such software could get used as well as provide a
bit closer look to a smart packet analysis.

In order to get an appropriate insight into a situation within
the network’s communications – it’s so important to deal with
the both – software and hardware.

Dealing with the hardware is from crucial importance
because that part of operation would define which segments
of the packets could get captured and transmitted to an
analysis.

Sometimes the beginners may deal with the equipment so
unskillfully and instead of capturing someone’s network’s
traffic; they would simply capture their own network’s
communications.

The Figure on the right would
suggest how the packets would
travel through the network and use
some of the storage devices on
that way to stay there for a while.

The parts of the network receiving
and sending the packets are
called the routers and so
commonly they would use the
switches to make such a
transmission more efficient.
