AccECN byte counter estimation requires delivered bytes which can be calculated while processing SACK blocks and cumulative ACK. The delivered bytes will be used to estimate the byte counters between AccECN option (on ACKs w/o the option).
Non-SACK calculation is quite annoying, inaccurate, and likely bogus.
Does it mean AccECN depends on SACK ?
