I don't think ppp allows this, but perhaps it Actually, the PPP multilink protocol allows this (and you can negotiate it even without any intention of using multiple physical links). However, it's only a two-level scheme. Obviously, what one would really like would be full ISSLOW support, but that may be some time off. > I'm not certain how this can be handled.

What multilink PPP allows you to do is interrupt one data stream temporarily to send a packet from another. (I'm remembering this from what was described at the first ISSLL WG meeting, so forgive me if I got it wrong.) You still have to go back to that packet eventually. -GAWollman -- Garrett A.
