Well, for X.25 (to pick an example, not necessarily my favourite) one can provide an IP mtu equal to the maximum packet size or one can use the M-bit to fragment an IP datagram transparently. For raw HDLC, one doesn't have acknowledgement or sequencing (at LLC1), so would have to be layered on top. Of course, with raw HDLC, one can usually set the MTU arbitrarily large (since this is typically over private point-to-point lines) so this isn't a problem... At least until Frame Relay happens. Unless you are referring to LAN technologies (which I feel offer a 'decent' size of MTU). -Philip
