Improving World Wide Web Latency

The HTTP protocol, as currently used in the World Wide Web, uses a separate TCP connection for each le requested. This adds signi cant and unnecessary overhead, especially in the number of network round trips required. We analyse the costs of this approach and propose simple modi cations to HTTP that, while interoperating with unmodi ed implementations, avoid the unnecessary network costs. We h...

Improving Palliative Cancer Care

Over a decade ago, the Institute of Medicine (IOM) presented Ensuring Quality Cancer Care in the United States, with recommendations for change (IOM, 1999). However, barriers to integrating palliative care (PC) to achieve high-quality care in cancer still remain. As novel therapeutic agents evolve, patients are living longer, and advanced cancer is now considered a chronic illness. In addition ...

Improving the Performance of the World Wide Web over Wireless

The World Wide Web (WWW) has become the largest source of Internet traffic, but it was not designed for wireless networks. Documents with large inline images take a long time to fetch over low-bandwidth wireless networks. Radio signal dropouts cause file transfers to abort; users have to restart file transfers from the beginning. Dropouts also prevent access to documents that have not yet been ...

Improving user-perceived performance at a World Wide Web server

—We examine a method to improve the service of incoming requests at a World Wide Web server. The motivating factor is the existence of an impatient user pool: a user aborts a pending web request if a response is not received within a random timeout period. We use a queueing theory approach to derive an optimal service ordering for this server, assuming Poisson arrivals and exponential service t...
