Good point: the UDP and TCP packets themselves do not explicitly carry the QoS requirements for the applications which sent (or expect to receive) them. However, the _applications_ themselves do have requirements, however ill-specified. That is a major aspect of the question: how _should_ UDP/TCP apps specify their QoS requirements if their packets will be transported always over IP and in turn sometimes over ATM? ------------------------------------------------------------------------ Stuart W.
