Currently, the bandwidth utilization of residential broadband links is highly inefficient. Providing the means for sharing these links will increase the total bandwidth and reduce the fixed costs per client thus promoting the use of Internet services. This paper proposes a low cost communal residential gateway for sharing and remotely managing broadband access links. We first identify and characterize...
Web-services and service-oriented architectures are gaining momentum in the area of distributed systems and Internet applications. However, as we increase the abstraction level of the applications we are also increasing the complexity of the underlying middleware. In this paper, we present a dependability benchmarking study to evaluate and compare the robustness of some of the most popular SOAP-RPC...
The design of systems with better performance is a real need to fulfil user demands and generate profitable Web applications. Understand user behavior and workload they produce on the server is fundamental to evaluate the performance of systems and their improvements. User reactivity, that is, how the users react to variable server response time, is usually neglected during performance evaluation...
The great success of the Internet has raised new challenges in terms of applications and the satisfaction of their users. In fact, there is strong evidence that a significant part of the user behavior depends on its satisfaction. Users reactions may affect the load of a server, establishing successive interactions where the user behavior affects the system behavior and vice-versa. It is important...
