Speaking from a personal interest, has the Point-to-Point Protocol
stopped being useful?
After all, PPP over Sonet/SDH was specifically designed for just this case.
Once upon a time, it worked well for intra-site connections, as originally
specified in RFC1619:
PPP encapsulation over high speed private point-to-point links, such as
intra-campus single-mode fiber which may already be installed and unused.
It was only after others crammed stuff in to make it work on inferior
quality long distance links that it became more expensive and complicated.
Still, it has all the testing and link configuration mentioned. And very
low overhead. And works on copper wiring, too....
