"Sniffer" technology is famous for helping to determine why a network is too slow and/or why something is not working properly. Many top notch sniffer packages include summaries of high-layer protocols contained in the frame/s, the time of the capture and the source IP. This type of "Network Analysis" provides the network admin a host of tools and details to capture and decode data on the network, analyze network activity by specific protocols, network stats, and patterns.

According to many experts; to be a successful network admin using Sniffer, you need a strong understanding of network protocols. This will help you understand and recognize odd issues when they occur on your target network.
