PPPoEoA DSL bandwidth shaping

2011-10-30 Thread Christopher Zimmermann
Hi, Bandwidth shaping on PPPoE links is difficult, because you don't know what the modem will do to you packets. On my DSL PPPoE links the DSL modem sends the ethernet frames over an ATM circuit and adds additional, but not constant overhead to each packet in the process. The consequence is that
