Allegro Network Multimeter is a diagnostic appliance designed for network administrators to analyse network traffic in real-time and historical contexts. It identifies network problems, performance bottlenecks, and packet losses quickly using powerful software algorithms. The tool provides high granularity analysis and works as both a troubleshooting appliance and monitoring tool for ensuring network quality. Available in ultraportable and stationary models ranging from 1G to 400G analysis rates, the appliance features an easy-to-use web browser interface. Data and statistics are accessible without delay for both current and historical network events, allowing administrators to isolate problem areas and capture pcaps from pre-selected network traffic for further detailed analysis.
