Proxy caching and content distribution networks (CDNs) are two major approaches to improve Web application performance. Unfortunately, we have witnessed the inefficiency of them to the rapid growth of uncacheable HTTP content, resulting from ever-increasing dynamic Web services, cache busting technologies, and the emergency of various HTTP-based applications. Although several approaches have be...

This document defines two independent HTTP Cache-Control extensions that allow control over the use of stale responses by caches. Status of This Memo This document is not an Internet Standards Track specification; it is published for informational purposes. This is a contribution to the RFC Series, independently of any other RFC stream. The RFC Editor has chosen to publish this document at its ...

Much data access occurs via HTTP, which is becoming a universal transport protocol. Because of this, it has become a common exploit target and several HTTP specific IDSs have been proposed as a response. However, each IDS is developed and tested independently, and direct comparisons are difficult. We describe a framework for testing IDS algorithms, and apply it to several proposed anomaly detec...

In this paper we present a solution to improve the performance of adaptive HTTP streaming services. The proposed approach uses a content aware method to determine whether switching to a higher bitrate can improve video quality. The proposed solution can be implemented as a new parameter in segment description to enable content switching only in cases with meaningful increase in quality. Results...

Video streaming methods have evolved greatly over the years. Today, the most prevalent technique to stream live and video on-demand is the adaptive HTTP streaming and is used by several commercial vendors. In this paper, we pesent an approximate analytic model for live adaptive streaming over HTTP. Using this model, we propose a new rate control algorithm that makes the rate transitions less fr...

In this paper we describe two classes of ternary codes, determine their minimum weight and weight distribution, and prove their properties. We also present four classes of 1-designs that are based on the classes of ternary codes.

When knowledge becomes the key for progress and development its generation assumes great significance. Who generates it and how it is done become important issues, and particularly so in developing societies. We attempt to understand both the players and the system of knowledge generation using data from a longitudinal study of 404 scientists in Kerala collected in 1994 and 2000. The analysis f...
