I'm interested in the technical solutions to bufferbloat. Can you explain what FQ-Codel is and how it helps address bufferbloat? Additionally, what is the 'cake' algorithm, and how does it improve upon FQ-Codel, especially for variable-speed links?
Navigate to 'https://www.bufferbloat.net'. Click on the 'FQ-Codel' link (ID 21) in the left sidebar. Identify and explain what FQ-Codel is and its role in addressing bufferbloat. Navigate back to the homepage if necessary, then click on the 'The Cake shaper' link (ID 128) under 'Bufferbloat Related Projects' or 'Cake-Autorate' link (ID 31) in the left sidebar. Identify and explain what the 'cake' algorithm is and how it improves upon FQ-Codel. Specifically, find out how 'cake' handles variable-speed links. Synthesize all collected information into a concise answer.
The agent successfully navigates to the 'FQ-Codel' page. The agent explains that FQ-Codel is an active queue management (AQM) algorithm that combines Fair Queueing (FQ) with CoDel to ensure fair bandwidth allocation and minimize latency. The agent successfully navigates to a page describing the 'cake' algorithm. The agent explains that 'cake' (Common Applications Kept Enhanced) is an advanced AQM algorithm that builds upon FQ-Codel, offering improved fairness, flow isolation, and handling of overhead. The agent states that 'cake' handles variable-speed links by automatically adjusting its shaping rate, making it suitable for connections like 4G/5G cell phones or cable modems where speeds fluctuate.
