I'm on VDSL. No idea what encapsulation (and can't access my > isp-provided router since that is in bridge mode). As far as I can tell at least VDSL typically means VDSL2 and = that probably means PTM instead of ATM. In essence this means you do not = have to deal with ATMs 48 payload bytes per 53 byte cell transport = inefficiencies. So all you need to deal with is per packet overhead. = Then again I am sure you probably know that already. (Sidenote, as far = as I understand (so not very far) using ATM for DSL connections with = POTS service in the lower frequency range never made much sense at all, = the 5 byte ATM header typically was constant and by that just ballast = and the 48 byte quantization on the last mile never came with any = benefits, but I digress) Best Sebastian >=20 > -Toke > _______________________________________________ > Cerowrt-devel mailing list > Cerowrt-devel@lists.bufferbloat.net > https://lists.bufferbloat.net/listinfo/cerowrt-devel
