Application Requested IP over ATM (Arequipa) and its use in the Web

: When using the Web over the TCP/IP protocol suite of the Internet, there is (yet) no possibility to guarantee bandwidth or delay for the transmission of a document. For the multimedia documents of the Web, transmission with guaranteed quality of service (QoS) is however very desirable. ATM networks which are being deployed now are one means of solving this problem. They offer high bandwidths and QoS negotiation at connection establishment. Current implementations of IP over ATM do not pass these advantages of the underlying network to the application level. Assuming that standard solutions involving RSVP [5] and NHRP [8] will not soon be available, we present a service built on a dual stack (IP & ATM) approach which allows to transport IP streams over application requested ATM connections. We show how this service can be used to offer guaranteed QoS to Web users on ATM while preserving compatibility with users which can not benefit of ATM connections. Finally we show how this solutio..
