There's a related discussion going on over on the make-wifi-fast list related to the FastACK scheme proposed by Meraki at this year's IMC: https://conferences.sigcomm.org/imc/2017/papers/imc17-final203.pdf It basically turns link-layer ACKs into upstream TCP ACKs (and handles some of the corner cases resulting from this) and also seems to contain an ACK compression component. -Toke _______________________________________________ Bloat mailing list Bloat@lists.bufferbloat.net https://lists.bufferbloat.net/listinfo/bloat
