How does Active Queue Management (AQM) such as CoDel address bufferbloat?
Correct! Well done.
Incorrect.
The correct answer is D) It tracks how long packets sit in the queue and proactively drops or marks packets once that sojourn time exceeds a target, signalling senders to slow down before queues grow large enough to cause excessive latency
Correct Answer

Bufferbloat occurs when oversized buffers let queues grow, adding latency without triggering congestion signals. CoDel measures each packet's time spent in the queue and drops packets once that delay persists beyond a target threshold, keeping queues shallow while still allowing bursts, prompting TCP senders to reduce their rate.
