Design & Implementation of Network Protocol Analyzer for Monitoring Network Traffic

Network Protocol Analyzer (NPA) is also known as packet analyzer, network analyzer, packet sniffer. NPA monitors exactly what is happening on Network & observes what other users are doing. It is easy to use tool to capture the traffic on the Subnet & display real time statistics while capturing packets.

In this paper we are analyzing network traffic & monitoring network by using filters. For that we are using runtime statistical & graphical representation as well as applying different constraints over attributes of LAN/Host. The system displays different attributes of LAN/Host likewise list of IP addresses that are active on the network, Display different protocol information sent, Source MAC, Destination MAC, Host name, Packet capture time , Length,etc.

NPA applied to detect protocol misbehaviors and failures in networks, it is required to analyze these protocols and inspect interactions among them. Filters plays important role for controlling packets which misbehaves.
