Overview Monitors our computers internet bandwidth usage. Records data in the database for future. Presents the data in graph. Is Open – source.

System Architecture

Used APIs Jpcap JFreeChart Objectdb

Jpcap-API Open source library for capturing and sending network packets. Can save captured packets to an offline file. Runs on: Microsoft Windows (98/2000/XP/Vista) Linux (Fedora, Mandriva, Ubuntu) Mac OS X (Darwin) FreeBSD Solaris.

JFreeChart-API Consistent and well-documented API, supporting a wide range of chart types. Supports many output types - Swing components including PNG and JPEG images.

Objectdb-API Database is a single file - easier backup, transfer and management. No proprietary API - managed only by standard Java APIs (JPA 2 / JDO 2). Suitable for database files ranging from kilobytes to terabytes. Can easily be embedded in applications of any type and size.

Completed Activities Proposal submission Codes for: Calculation of packet size every second. Writing into the database. Simple GUI.

Challenges Faced Packet capturing- since there are no any inbuilt Java libraries. Freezing issues – solved by making multiple threads. Making automatically updating JLables. Creating dynamic graphs/charts.
