Predictable Quality Of Service (QoS) in terms of controlled response time and guaranteed bandwidth is increasingly important in World Wide Web. We propose a variety of enhancements and extensions to the existing Web infrastructure so that Web applications and applets can provide predictable quality of service. The proposed extensions include addition of the notion of QoS to the HTML/HTTP/Java syntax, QoS negotiation and adaptation mechanisms in Java classes and threads, QoS reservation support at the socket and transport protocol layers, and ATM signaling extensions for dynamic QoS re-negotiation over persistent HTTP connections. Our ongoing work includes implementation of these extensions and an evaluation over a testbed consisting of a network of Unix workstations and ATM switches.
