Network Traffic Analyser

Introduction

Internet Traffic analyzer is built to offer comprehensive network traffic analysis for all your network elements by automatically collecting and correlating traffic data. Gain insight into network traffic patterns for any network element. ITA is built to collect and analyze flow data from multiple nodes and multiple IP’s. ITF identifies the blacklisted IP address from where hacking attempts are performed or illegal activities are performed. The main purpose of internet traffic analyzer is to play an important role in network maintenance, troubleshooting, and network security as well. The typical use of a packet analyzer is to analyze network traffic, troubleshoot the network. It can help identify malicious activity, Increase the efficiency of the network by identifying the blacklisted IP. A Network Traffic Analyzer decoded or dissects the data packets of common protocols like TCP, ARP, UDP, SMTP, etc., and displays the captured packets in a human-readable format. The captured traffic is decoded and further used to detect various types of network attacks.

Background of the System

Network traffic analysis is the process of collecting and examining network data to understand and improve the performance of your network. Network traffic analysis can allow you to identify bottlenecks in your network causing slowdowns or may soon impact the quality of service for end- users.

Network traffic analysis is often focused on leveraging flow data for insights into bandwidth usage across your network. Networks are designed with a limited amount of bandwidth. When an array of applications, endpoints, and users are using this bandwidth, performance issues can arise. With network traffic analysis, you can identify bandwidth-consuming applications, users, protocols, or IP address groups, also known as “top talkers.” In this way, network traffic analysis can help you avoid overloading your network capacity and ensure the end-user experience is satisfactory. Traffic analysis is an activity to record knowledge from user activities in exploiting the net. This study aims to induce knowledge concerning the results of traffic throughout a graphical type so that it will verify the number of users who access the net and use bandwidth. Internet traffic analyzer is installed on the gateway machine and traffic captured can be then used for network statistics collection, network debugging, and as far as advanced security monitoring and information collection suites.

In this project our focus is on the blacklisted IPs, to identify them. Objectives of the System. The main objective is to capture network traffic and inspect it deeply to determine what is happening on the network. The network analyzer decodes or dissects the data packets of common protocols e.g., TCP, ARP, UDP, ICMP, IGMP, POP3, etc. including header and footer. and displays the captured packets in Human-readable format for further analysis.
