No, that's not the goal as I understand it. It's to tell the client that asking for 4K video is not going to work. Yes, it might be able to get an initial few seconds of 4K, but then the bur= st tolerances (token buckets, etc.) of the network will be exhausted, and the = 4K will begin to fail. The video will then pause/skip/.. and the client will go back to 2K. Lather. Rinse.

When I think about QUIC, I think about PsyDuck for some reason. When I think about TCP, I think about JigglyPuff. Or maybe Kirby (not a pokemon). And, when I think about UUCP, I think about Thomas the Tank Engine. Yes, I was a parent over the last 20 years. -- ] Never tell me the odds! | ipv6 mesh network= s [ ] Michael Richardson, Sandelman Software Works | IoT architect = [ ] mcr@sandelman.ca http://www.sandelman.ca/ | ruby on rails = [
