+1 ... the message in the paper is applicable to layered systems and internetworks in general. Changes in the link technology since then don't invalidate it, especially since we know that the technology not only changes rapidly, but also is always growing in diverse directions, such that there things almost universally true today may be turned on their heads tomorrow. Designs for stacking layers need to follow solid general principles in order to be robust to changes (above and below). -- Wes Eddy MTI Systems _______________________________________________ lisp mailing list lisp@ietf.org https://www.ietf.org/mailman/listinfo/lisp
