While this is certainly true, HDLC is a point-to-point protocol and not a network protocol, like frame relay, SMDS or ATM. And HDLC itself isn't quite enough, IMHO, you really need PPP. And the efficiency lost to ATM is not 40% as often claimed on this list, but rather it is 12% less efficient than PPP for TCP. 10% is the cell header overhead and 2% is due to modulo 48 padding, given actual traffic at FIX West as measured by kc at NLANR. --Kent We return to our regularly scheduled ATM tweaking program now in progress. :-) - - - - - - - - - - - - - - - - -
