CoDel (Controlled Delay)

CoDel (Controlled Delay) is a network traffic management technique designed to reduce latency and prevent network congestion. It works by monitoring the time packets spend in a system’s buffer (queue). When delays get too high, CoDel automatically reduces the buffer size to prevent delays from increasing further. This helps maintain smooth data flow and minimizes lag, especially important for real-time applications like video calls or online gaming. Essentially, CoDel adapts dynamically to network conditions to keep delays low and improve overall performance without needing manual adjustments.
