The idea is to go to the ISP community and say "Please treat LE as BE in your core/peering links, and only act on it on the customer access shaper (optional). Please don't bleach it." 000001 has never been in use before, so the hope is that people will allow this to happen. CS1 has had different meanings over time so it's harder to handle. The problem with CAKE/FQ and background traffic is that it can't tell if there is congestion or not, and things like LEDBAT can't backoff and try to avoid causing congestion. So your previous email about allowing some congestion to take place on LE would be good as then protocols that try to avoid causing congestion would have a way to do so. -- Mikael Abrahamsson email: swmike@swm.pp.se
