BLËSK Network Traffic Analyzer (NTA) is a sniffer that captures the continuous flow of network traffic and presents the data in graphs and tables. These can provide valuable information on how your network is being used. It is a simple, portable traffic measurement and monitoring tool, which supports various management activities, including network optimization & planning, and detection of network security violations.
See the Quick Start guide for examples on how to capture and send data to NTA.
