A combination of distributed computation, positive feedback and constructive greedy
heuristic is proposed as a new approach to stochastic optimization and problem solving …

This article presents a detailed workload characterization study of the 1998 World Cup Web
site. Measurements from this site were collected over a three-month period. During this time …

The ability to generate repeatable, realistic network traffic is critical in both simulation and
testbed environments. Traffic generation capabilities to date have been limited to either …

New source-level models for aggregated HTTP traffic and a design for their integration with
the TCP transport layer are built and validated using two large-scale collections of TCP/IP …

We report the results of a large-scale empirical study of web traffic. Our study is based on
over 500 GB of TCP/IP protocol-header traces collected in 1999 and 2000 (approximately …

In order to perform realistic network simulations, one needs a traffic generator that is capable
of generating realistic synthetic traffic in a closed-loop fashion that" looks like" traffic found …

Packets are the basic unit of the Internet. Yet, most user operations involve more than one
packet and user experience depends on the performance of the network on a set of packets …

This article provides a detailed implementation study on the behavior of web serves that
serve static requests where the load fluctuates over time (transient overload). Various …

In this paper we present a new model of Web traffic and its applications in the performance
evaluation of Web servers. We consider typical user hypertext navigation behavior within a …

The typical Web cluster architecture consists of replicated back-end and Web servers, and a
network Web switch that routes client requests among the nodes. In this paper, we propose …
