I'm experiencing network lag and suspect bufferbloat. Can you explain what bufferbloat is, and what the primary technical solutions are provided by this website? Specifically, describe FQ-Codel and how it addresses bufferbloat, and then explain how the 'cake' algorithm improves upon FQ-Codel, especially for variable-speed internet connections like mobile hotspots or cable modems.
Navigate to 'https://www.bufferbloat.net'. Read the introductory section on the homepage to understand what bufferbloat is. Click on the 'FQ-Codel' link in the left sidebar. Identify and explain what FQ-Codel is and its role in addressing bufferbloat. From the FQ-Codel page, click on the 'cake' link to navigate to its technical information. 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 'https://www.bufferbloat.net'. The agent explains that bufferbloat is the undesirable latency caused by network equipment buffering too much data. The agent successfully navigates to the 'FQ-Codel' page. The agent explains that FQ-Codel is an active queue management (AQM) algorithm combining Fair Queueing (FQ) with CoDel, designed to minimize latency and ensure fair bandwidth allocation. The agent successfully navigates to the 'Cake Technical Information' page. The agent explains that 'cake' is a comprehensive queue management system that improves upon FQ-Codel by integrating more functionality, simplifying configuration, and using a 'deficit mode' shaper to minimize bursts without manual tuning. The agent states that 'cake' handles variable-speed links by automatically adjusting its CoDel parameters (target and interval) based on the shaper bandwidth, making it suitable for fluctuating connections.
