What is Bufferbloat and How to Fix It?


Bufferbloat is like a traffic jam in your internet connection. When too much data arrives at once, your router or modem tries to manage it by putting it in a line (like cars in a traffic jam). If this line gets too long because it’s trying to handle more data than it can quickly process, it causes delays. This is like waiting longer at a traffic light, making everything online slower. This can mess up things that need fast and steady internet, like video calls or online games.

What causes bufferbloat?

Bufferbloat happens when routers and modems receive more data than they can handle quickly. They try to manage this by storing the extra data in a buffer (like a waiting room), but if this buffer gets too full, it leads to long delays in data transfer. This is similar to being stuck in a slow-moving line.

How can bufferbloat be solved?

To solve bufferbloat, routers need smarter ways to manage data. Techniques like CoDel (Controlled Delay) and FQ-CoDel (Fair Queuing Controlled Delay) are used to prevent the buffer from getting too full. These methods help keep the internet running smoothly by making sure data doesn’t wait too long in the buffer before being sent to its destination.
