Reasons behind the failure and success of large-scale information systems projects continue to intrigue researchers. In particular in the airline industry very successful (passenger reservation) systems have been built which have totally changed the competitive arena of the industry. On the cargo side however attempts to implement large-scale community systems have largely failed across the glo...

This paper proposes a virtual memory management system suitable for interactive continuous media applications. Our virtual memory management system enables continuous media applications to reserve physical memory for allocating pages as soon as possible when the applications require the pages. The system implicitly and incrementally allocates and wires pages used for processing timing critical ...

We wish to provide quality of service (QoS) to scientists who are remotely controlling experiments on singular instruments such as the LBL Advanced Light Source (ALS) or who need to harness heterogeneous and distributed computing resources to perform large-scale computation. To ensure the timely availability of the computing, storage, and networking resources required for data collection and/or...

Distributed continuous media applications that incorporate digital audio and video require predictable response from the operating system and the network. Much recent research in communication networks focuses on providing predictable service at the network level, but current operating systems do not typically provide end-to-end predictability. Our aim is to offer operating system support for p...

In this paper, we introduce a new operating system abstraction called reservation domains, and describe its implementation in Eclipse, an experimental operating system that provides a testbed for Quality of Service (QoS) support for applications. Reservation domains enable explicit control over the provisioning of system resources among applications in order to achieve desired levels of predict...

These paper introduces a reservation subframe protocol for multimedia services in a 3rd generation mobile telecommunication system. The Packet Reservation Multiple Access (PRMA) protocol is modified to achieve more efficient bandwidth management. Simulation results show that the resulting multiple access multimedia system can serve a large number of users with low probability of packet loss, en...

One of the largest operators of hotel properties, with over 7,200 hotel properties in every category _ from upscale to economy _ was faced with a challenge when it came to its reservation system. As mergers and acquisitions emerged as a popular solution to the decline of occupancy and revenue across the industry, the hotel operator, known for its exceptional customer service and value, sought a...

Recommender systems are important tools for users to identify their preferred items and for businesses to improve their products and services. In recent years, the use of online services for selection and reservation of hotels have witnessed a booming growth. Customer’ reviews have replaced the word of mouth marketing, but searching hotels based on user priorities is more time-consuming. This s...
