What Is Anti-buffer Bloat?
What the $%&*! is Anti-buffer bloat??
Hey Nighthawks,
Here's a quick explanation of one of the most powerful features in the OS that powers our Nighthawk Pro Gaming routers, anti-buffer bloat.
What is anti-buffer bloat? Before we can answer that, we should answer what the heck is buffer bloat? Buffer bloat is a major cause of high lag in networks caused by excess buffering of packets or information. Bufferbloat can also cause packet delay or jitter, as well as reduce the overall network speed. When a router is configured to use excessively large buffers (like HD video or several streaming devices), even very high-speed networks can become practically unusable for many interactive applications like voice over IP (VoIP), online gaming, and even ordinary web surfing.
Simply put, if you have a device or multiple devices like Google Chromecast, Amazon Firestick or smart TVs, the preloads for showing you a little bit of that movie or show is buffered. Now, it’s great that they can serve up that content immediately, but that’s contributing to bufferbloat. All of those devices add up and start to vampire a little of your overall internet until things start to slow down.
Anti-buffer bloat is designed to remedy this problem by reserving a percentage of your overall internet for interactive applications like VoIP and online gaming.
Think of it as a bouncer that let’s your gaming traffic into the VIP line and things like streaming services get to wait in line like everyone else.
Till next time,
ZarduBen

That's correct. So you may want to increase it to 80% or 90% once you're comfortable with your setup. I wouldn't recommend going above 90% though because if your ISP underprovides against your speeds it will mean Anti-Bufferbloat will no longer be taking affect.

Re: What Is Anti-buffer Bloat?
BufferBloat is when the traffic going through the modem overloads the modems buffer. It is a big issue with the puma 6 chipset modems. when the modems buffer gets congested it results in packet loss and line jitter. You can test for bufferbloat with DSLreport's speedtest. It is an issue that should be fixed with docsis 3.1 modems. I just picked up an xr500 today and adjusted my bufferbloat settings in the xr500 according to the results the dslreports speedtest was giving me. Without the bufferbloat settings active in the router I was having the bufferbloat reading spiking into the red throughout the entire test. I was able to fine tune it to get about 195 of my paid 200 meg connection through without the bloat spiking to unacceptable levels. I am working on getting my internet provider to assign me a docsis 3.1 modem as they are not allowing customer owned 3.1 modems despite being listed as minimally qualified on their own website.
