I'm looking to try and handle at least 4Gbit and 20,000 sessions worth of PPPoE -> L2TP LAC traffic per server. The reading I've done from the archives so far seems to indicate that this has not yet been done.. probably not with a single machine but it should be possible to use several machines and pppoe is designed to allow multiple providers to co-exist on the same network. 20,000 is probably high.. I've heard of 8000 but I have no idea of how well it worked or what they had to tweek.. 4Gb is also pushing it if you want to be dong other work at the same time. having said that, maybe 3 fast machines together could do it.. "maybe" becasue I haven't tried using those components since I wrote the pppoe module in '97 and a lot has changed since then. > So my questions to you are: > A) Can it be done? > "maybe" > B) Am I crazy?
