  Current Internet applications cannot take advantage  of the variety of
  service classes offered by ATM networks.  This is due to the stacking,
  without specific scheduling mechanisms, of a best-effort network layer
  on  top of ATM. Simultaneously,  few native ATM applications have been
  written   specifically in  this  networking framework.   I  present an
  architecture  for running   TCP-based  applications  over ATM.    This
  architecture relies on  the  standard TCP protocol  and  offers at the
  socket layer the means to specify an ATM traffic contract.  This gives
  an immediate native ATM  access to a  set of familiar applications. It
  also  helps  satisfy the  increasing  need  of  resource  control  for
  Internet applications. I present  TCP-ONIP, a prototype implementation
  of  this approach. The necessary  adaptation steps will be outlined in
  the case of the Web and Mpeg.
