So how > does compression/encription work? Most of the algorithms involved either have their own sequence numbers or have some mechanism for detecting a loss of sender/receiver synchronization. Even if there's reordering and loss, those algorithms can generally deal with it. (Though, of course, with a performance penalty.) > Is there anything i am missing? Just that PPPoE doesn't run over IP, I think. I wouldn't recommend running compression or encryption with PPPoE, as these tend to magnify any errors that occur, but they should work as specified. -- James Carlson, IP Systems Group? <[email protected]> Sun Microsystems / 1 Network Drive 71.234W Vox +1 781 442 2084 MS UBUR02-212 / Burlington MA 01803-2757 42.497N Fax +1 781 442 1677 _______________________________________________ Pppext mailing list [email protected] https://www1.ietf.org/mailman/listinfo/pppext
