Packet per second (Pps) is a metric used in networking to measure the number of data packets transmitted through a network every second. Unlike bandwidth, which measures the amount of data transferred, Pps focuses on the count of individual packets regardless of their size. This measurement is important for assessing network performance, detecting unusual traffic patterns, and identifying potential security threats such as Distributed Denial of Service (DDoS) attacks, which often involve a high volume of packets. Monitoring Pps helps network administrators ensure smooth data flow and maintain the reliability of digital communications.
