Temporally consistent delivery of time-sensitive information : solutions and challenges

Abstract

The web and the internet have become the dominant infrastructures for information access and dissemination. Even time varying information such as currency and stock prices, real-time data needed for tele medicine, etc., are being delivered via the Web. Clearly, the Quality of Service needs for delivering such time-critical data are much more stringent than for static Web pages. This paper examines the nature of the dynamics on the Web, studies the suitability of the current infrastructure for disseminating time varying information, and discusses fresh approaches tailored for dynamic data. A challenging and fruitful research direction is to examine the use of a control theoretic framework to address the problem of tuning the algorithms needed for adaptive data delivery.
