NETWORK PROTOCOL ANALYZER is an advanced, professional tool for analyzing, debugging, maintaining and monitoring local networks and Internet connections. It captures the data passing through the dial-up connection or network Ethernet card, analyzes this data and then represents it in an easily readable form. Network Protocol Analyzer is a useful tool for network administrators, security specialists, network application developers and anyone who needs a comprehensive picture of the traffic passing through their network connection or segment of a local area network. The flexible system of fully configurable filters can be used to discard all network traffic except the specific traffic patterns to wish to analyze. Network Protocol Analyzer also has a special packet builder. This tool allows to build your own custom network packets and send them into the network. This system could use this packet builder feature to check your network for protection against attacks and intruders.
Network Protocol Analyzer enables to see statistics on specific nodes including communications traffic details and node information for active nodes on the monitored side of the switch.
Individual Active Node Information:
• Packets Transmitted and Received
• Bytes Transmitted and Received
• Utilization Information
• IP Address and MAC Address
• Assigned User Friendly Names for each Node
This system turns any network-ready Windows PC into an protocol analyzer that is optimal for both traditional enterprise LAN troubleshooting applications, and for the growing number of situations in which data communication professionals must support both Ethernet and serial applications or networks. The feature-rich protocol analyzer offers the comprehensive suite of protocol decodes and comprehensive array of network statistics demanded by today's enterprise network managers. The common user interface significantly shortens the learning curve for engineers, network troubleshooters, and field service technicians working with multiple network topologies, such as serial and Ethernet.
This system runs on any Windows XP ,Windows 95/98/ME/NT/2000/XP/Vista Operating system compatible PC. The product supports all Windows compatible network interface card types .
The software requires Windows 95/98/ME/NT/2000/XP/Vista Operating system compatible PC. The project is developing in VB.Net as Front End and Windows Operating system.
MODULE DESCRIPTIONS
• PACKETS TRANSMITTED AND RECEIVED
Packets transmitted and received is a LAN information is exchanged between nodes and server or nodes and nodes information is exchanged as packets. Each packet is having a definite frame work. The frame work consists of a header information data bytes and other message specific information like message end. The transmitting nodes will send to with information of receive machines. So that the packet will received only addressed machine. In Ethernet LAN technology involves is CSMA, Coalition Sense Multiple Access. Since each node is linked to the LAN. The packets from each node will be traveling in the same media, namely UTP Cable. In order to make available to an end to end communication between two machines CSMA Technology is used. The packets must be send by the transmitted nodes must be received by the receiving machine. If coalition occurs it will be sensed by the nodes as the medium is in used and the packets will send again.
• BYTES TRANSMITTED AND RECEIVED
In packet of information there are various information namely packet header, data and end of message. In this format data is the actual no of bytes transmitted by the server or node. After receipt of the packet of information from the Network the receiving machine will converted into the actual bytes of information. The Network protocol analyzer will verify the actual bytes of information transmitted by the transmitting machine and actual number of bytes received by the receiving machine. This will give the exact measure of efficiency of the Network in terms of actual usable number of bytes of information.
• UTILIZATION INFORMATION
This software will give a summary report of Network medium utilized by different nodes in the LAN. This is the very important in the LAN in nodes to plan Network management activities by the Network administration
• IP ADDRESS AND MAC ADDRESS
Every machine will have on internet protocol address allotted manually or dynamically. This address is retrieved from the machine and given by the utility for information. MAC address is the unique address of the NIC card of the machine this unique address is very important as for as Network communication is concerned. This address is taken out from the NIC BIOS and will be displayed by this software.
• ASSIGNED USER FRIENDLY NAMES FOR EACH NODE
In Network the user will assigned a computer name for each node. This name can be displayed by the Operating system in the respective machine. This Software taken out the information and displayed for the user.
