Leveraging P4 Switch Passive Measurements for Dynamic Router Buffer Sizing

This research presents a system that leverages passive measurements from P4 switches to dynamically adjust a router's buffer size for optimizing network performance. By computing factors like long flows, round-trip times, queue delays, and packet losses, the system dynamically searches for an optimal buffer size to minimize delays and losses. Through extensive evaluation with different network scenarios and congestion algorithms, the system shows promising results in balancing flow completion times and improving network efficiency.
