Hi there. I've read some materials from bufferbloat.net and other sites, trying to understand the problem as best as I can.

And I have a question when reading this:

From https://www.bufferbloat.net/projects/bloat/wiki/What_can_I_do_about_Bufferbloat/ , it says:

Once you fix it for your own network, it’ll stay fixed for all time, and you won’t be subject to changing practices at your ISP or other vendors.

What does it mean?

Does it mean that :

if I employ a Smart Queue Management algorithms on my home router, it only solves the bufferbloat problem between my home devices (desktop, laptop ,cellphone) to my home router. But the buffers between my home router to upstream devices (my home router ---> modem ---> ISP routers/switches) , buffers between upstream devices, will still harm? So I only fix the bufferbloat problem on my own local network?

or it mean that employing a Smart Queue Management algorithms on the home router also solve bufferbloat between home router and upstream devices?

Thanks in advance.
