NETWORK ANALYZERS:
A network analyzer also known network monitor or a network sniffer is used to calculate the performance of or debug a network.
It may report statistics such as capacity distribution of frame size, utilization, token circulation time or collision rate.
OPERATION OF NETWORK ANALYZERS:
The main idea behind the function of network analyzer is a device with a network interface that accept all frames, which is known promiscuous mode. Several desktop computers have interface that may be configured for promiscuous type. When combined with software computer can calculate any frame on LAN. In this way the interaction across LAN is have to be private. This device receives and displays frames on the LAN.
Network analyzer may be configured to process and filter frames. It may count frames of specific kind of size. It shows only frames from or to specific device. In general it may be configured to check any value of any field and save only these frames acting the filter specifications.
