ELI5: Explain Like I'm 5

QPPB

QPPB (Quality of Service Policy Propagation via Border Gateway Protocol) is a really fancy way for computers to talk to other computers and decide how important certain information is. Think of it like sharing toys with your friends. When you have a lot of toys to share, you may want to let your best friend have first pick because they are really good at sharing back.

Similarly, with QPPB, computers talk to each other and decide which information is most important, and what order it should be sent in. For example, when you're watching a YouTube video, you don't want it to stop and buffer all the time, so QPPB makes sure that your computer gives priority to the video data, while other less important information like email can wait a little longer to be sent.

It's important for QPPB to work well so that you can have a smooth experience using the internet without interruptions, just like how you want to have a fun time sharing toys with your friends without being interrupted by other things.
