Network Packet Sniffer

About Network Packet Sniffer:

Network packet sniffer is simply a web-based application that monitors all traffic over a network. Unlike other standard network hosts that only track traffic sent particularly to them, this software captures each packet, eventually decoding and analyzing its data as the data streams flow across the system network.

This project, developed in Java, shows mainly two things:

1. how real-time network connection behavior can be modeled as chromosomes
2. how the parameters in genetic algorithm can be defined in this respect.

The objective of the proposed project is to create a set of rules during run time so that hackers and intruders cannot attack the system software with virus and malwares. So, for networking purposes, network packet sniffer monitors all LAN data packets and mirrors all packets that are being passed through a shared bus.

Existing System:

In the existing system, network administration and monitoring is done by an admin. Admins are mainly assigned the task of identify, diagnosing, and solving network problems, but this overall becomes a very tedious task as network administration needs to put a lot of effort to identify traffic.

Additionally, the existing system is very time taking and uneconomical. There is no such thing as automatic network control because the network administrator must always be present to monitor traffic over the network.

Proposed System:

As a network analyzer, the proposed packet sniffer software makes it easy to identify, diagnose, and solve network problems. With the software’s information-rich and intuitive tab views, it can track all incoming and outgoing calls over the network.

The key features of packet sniffer application are listed below:

• real-time packet capturing
• 24×7 network monitoring
• advanced protocol analyzing
• comprehensive packet decoding
• automatic expert diagnosing
• complex network analyzing
• conduct packet level analysis
• solve network problems

Modules Used:

Network packet sniffer is made up of 3 modules:

1. User Interface Module: It provides all the Graphical Interfaces components required by the user to interact with the system.
2. Packet Analysis Module: It analyzes all the incoming packets into the desktop, and upon proper identification and clarification, passes the data into statistics module.
3. Statistics Module: This module is responsible for all the necessary calculation based on the data, information, or content received from packet analysis module. It then produces information that can be understood by the system user.

So, in conclusion, with the proposed network packet sniffer software, network administrator can monitor the packets anywhere throughout the the world. System performance will be enhanced and traffic will be controlled. Further, reports can be generated immediately and graphical data is readily available to analyze the network.
