Generating representative Web workloads for network and server performance evaluation
Paul Barford,Mark Crovella +1 more
TL;DR: This paper applies a number of observations of Web server usage to create a realistic Web workload generation tool which mimics a set of real users accessing a server and addresses the technical challenges to satisfying this large set of simultaneous constraints on the properties of the reference stream.
Proceedings ArticleDOI
A signal analysis of network traffic anomalies
TL;DR: This paper reports results of signal analysis of four classes of network traffic anomalies: outages, flash crowds, attacks and measurement failures, and shows that wavelet filters are quite effective at exposing the details of both ambient and anomalous traffic.
Proceedings ArticleDOI
Power Awareness in Network Design and Routing
TL;DR: This paper describes the power and associated heat management challenges in today's routers and advocates a broad approach to addressing this problem that includes making power-awareness a primary objective in the design and configuration of networks, and in theDesign and implementation of network protocols.
Journal ArticleDOI
Changes in Web client access patterns: Characteristics and caching implications
TL;DR: This study compares two measurements of Web client workloads separated in time by three years, both captured from the same computing facility at Boston University and finds that for the computing facility represented by traces between 1995 and 1998, the benefits of using size‐based caching policies have diminished and the potential for caching requested files in the network has declined.
Proceedings ArticleDOI
Characteristics of internet background radiation
TL;DR: This work breaks down the components of background radiation by protocol, application, and often specific exploit; analyzes temporal patterns and correlated activity; and assess variations across different networks and over time.
