In this paper we present the application of the Transform Regression (TR) algorithm to predict file transfer time. We consider the files that are transferred from Web servers using HTTP protocol. We identify parameters having impact on file transfer time and use them as inputs to transform regression. We compare the results of TR-based prediction with the(More)
In this paper we propose an application of data mining methods in the prediction of the availability and performance of Internet paths. We deploy a general decision-making method for advising the users in further usage of Internet path at particular time and date. The method is based on the clustering and tree classification data mining techniques. The(More)
This paper presents a novel algorithm for distribution of user requests sent to a Web-server cluster driven by a Web switch. Our algorithm called FARD (fuzzy adaptive request distribution) is a client-and-server-aware, dynamic and adaptive dispatching policy. It assigns each incoming request to the server with the least expected response time, estimated for(More)
