Optimising MTU setting in PPPoE ADSL Connections
Authored by: cahaddras on Aug 26, '05 06:52:27PM

There are further protocol layers to take into account. In addition to the 1454 for the IP packet, the complete payload before splitting into ATM cells contains 2 for the PPP header, 6 for the PPPoE header, 14 for ethernet, 2 for VCMux, and an 8 byte AAL5 trailer. PPPoE is not very efficient!
