Do we need a real-time protocol that is highly reliable in the world? The answer, is of course YES.
NO. Name the single application which couldn't be run over lossy protocol.
Thats an easy one.... Any generic system that receives time sensitive real-time information from numerous distributed nodes that must be processsed and relayed to other processing stations *and* run the typical IP e-mail, ftp, httpd, etc. packet services concurrently over the same pipes, as well as network management traffic ad. infinitum..... Running real time sensory data, for example that must arrive at remote locations within a few milliseconds on a packet switched network, for example.... I'll attach a few references for those who don't wish nor have the time to pull down the 12 page postscript draft mentioned earlier... --------- attached -------- \bibitem[Ferrari90]{Ferrari90} Ferrari, Domenico, {\em Client Requirements for Real-Time Communication Services}, IEEE Communications Magazine, November 1990, pp. 65-72. \bibitem[CSZ92]{CSZ92} Clark, D., Shenker, S., and Zhang, L., {\em Supporting Real-time Applications in an Integrated Services Packet Network: Architecture and Mechanism}, ACM SIGCOM, September 1992. %\bibitem[QoS95]{QoS95} Lee, W., Hluchyj, M., and Humblet, P, %{\em Routing Subject to Quality of Service Constraints in Integrated Communications Networks}, %IEEE Network, July/August 1995, pp. 46-55. \bibitem[Zhang87]{Zhang87}Zhang, Lixia, {\em Designing a New Architecture for Packet Switching Communications}, IEEE Communications Magazine, Vol. 25, No. 9, September 1987, pp. 5-12. ------- end -------- Hope these help, there are more......
