thoughts for next draft long off-list discussions haven’t resolved differences, but could main points in favour of size-dependent drop: control packets tend to be small (e.g. SYNs, pure ACKs) so less drop of small packets gives performance win already have mix of size-dependent (drop-tail) and size-independent drop so doesn’t reduce complexity by only having size-independent apps have other (OS) incentives not to use small packets main points in favour of size-independent drop not all small pkts are control, so favouring all smallness creates unintended consequences the more size-independent AQM, the less transport uncertainty over queue behaviours mustn’t provide incentives for new transports to use small data pkts possible ways forward focus only on PCN? but still mileage in reaching consensus on RED too |
