JAVA 2013 IEEE DATAMINING PROJECT Distributed web systems performance forecasting

  1. 1. Distributed Web Systems Performance Forecasting Using Turning Bands Method Abstract With the increasing development of distributed computer systems (DCSs) in networked industrial and manufacturing applications on the Worldwide Web (WWW) platform, including service-oriented architecture and Web of Things QoS-aware systems, it has become important to predict the Web performance. In this paper, we present Web performance prediction in time and in space by making a forecast of a Web resource downloading using the Turning Bands (TB) geostatistical simulation method. Real-life data for the research were obtained in an active experiment conducted by our multi-agent measurement system WING performing monitoring of a group of Web servers worldwide from agents localized in different geographical localizations in Poland. The results show good quality of Web performance prediction made by means of the TB method, especially in the case when European Web servers were monitored by an MWING agent localized in Gliwice, Poland. Existing System The aim of this paper is to present a robust spatio-temporal prediction method and algorithm that can provide an efficient forecasting of a Web client-perceived performance on the World Wide Web. This may provide efficient QoS for individual nodes of Web-based DCS and enable to improve operation of the whole system. The predicted performance characteristics can be used in selection of the best performance Web server and best in space and in time. Here, we propose to make Web performance prediction with the use of the Turning Bands (TB) geostatistical method some of the main contributions of the paper are as follows. The first is the introduction of a new spatio-temporal methodological approach to the performance prediction of Internetbased DCSs, established on the theory and application of geostatistics.

  2. 2. algorithm based on the widely proven TB simulation method, which gives efficient and accurate forecasting, as well as reliable results. Disadvantages The third contribution is that our analysis uses real-life data collections gathered for various clients monitoring many Web servers localized in different Internet geographic locations. At present, to the best of the authors’ knowledge, the approach presented in this paper is unique, and there is no similar problem statement in the literature with which to compare. The present the comparison of our TB-based Web performance prediction method with other spatio- temporal prediction approaches, which, like the TB method, were studied Proposed System The methodology of the proposed approach and the algorithm of the TB method, which will be used for spatio- temporal forecasting of Web system performance (WSP). The basic assumption of the TBmethod is as follows: the field to be simulated is second-order stationary and isotropic; at each point, the values of the field are normally distributed and have zero mean. In other cases, the transformation to Gaussian with subsequent subtraction of the mean could be applied. The next assumption is the knowledge of the covariance C(r) of the field which is to be simulated. agents implemented in different programming languages, so it can be run in both Linux and Windows operating environments. Agents perform measurements and monitoring by means of common system functionalities as well as on open developments aiming to match specific aims of measurements. Common functionalities include: agent management, measurement scheduling, heartbeat (status and conditions of an agent), data model, synchronization, local databases, and central database support. The network delay, the web server latency, and the delay caused by the special web infrastructure, built on the client-to-server communication path to reduce the response time, if only exist. Finally, a web client always perceives the grand total delay resulted from all activities. Advantages The information regarding an area of forecast, a time of forecast, a geostatistical method, and an agent from which datasets were collected. As a result, one could obtain spatial-temporal database and rastermap, where the analyses of variability for whole space not only for given points could be performed.
  3. 3. These two methods have been used by us because they use an acceptable amount of casts. Geostatisticalmethods are developing significantly in traditional sciences for geostatistics like climate studies, geology, ecology, or agriculture Modules Description Forecasting There are generally two ways of solution of problems caused due to the imperfect performance of the Web. The first is making improvements in the quality of communication protocols, including the development of real-time protocols, protocol tuning, as well as upgrading existing network technologies to support needed communication requirements. This development is finely realized for Web-based systems of general usage and includes, for example, content distribution networks. Client-perceived performance The aim of this paper is to present a robust spatio-temporal prediction method and algorithm that can provide an efficient forecasting of a Web client-perceived performance on the World Wide Web. This may provide efficient QoS for individual nodes of Web-based DCS and enable to improve operation of the whole system. The predicted performance characteristics can be used in selection of the best performance Web server and best in space and in time. Here, we propose to make Web performance prediction with the use of the Turning Bands (TB) geostatistical method. Turning Bands The basic assumption of the TB method is as follows: the field to be simulated is second-order stationary and isotropic; at each point, the values of the field are normally distributed and have zero mean. In other cases, the transformation to Gaussian with subsequent subtraction of the mean could be applied. The next assumption is the knowledge of the covariance C(r) of the field which is to be simulated. Structural Data Analysis The minimum and maximum values, a rather large data range is observed. Only for data measured at 12:00 a.m. is this difference smaller. Moreover, the high value of standard deviation and the coefficient of variation, which is above 100% for each considered hours, confirms the process variation. However, the coefficient and kurtosis values indicate that the distribution of the considered web performances should show similarity to a symmetrical distribution but with only small right-side asymmetry.
  4. 4. Distributed Web System The simulation, the moving neighborhood type was adopted where the search ellipsoid was 10 km for the - and –directions and 18 km for the -direction in the case of Web performance at 6:00 a.m. and 12:00 a.m., and for the -direction at 6:00 p.m. The search ellipsoid was 28 km. The forecast of the download time was determined on the basis of 100 simulation realizations. Performance prediction The Formula-based methods use a mathematical formula expressing particular performance measure as a function of essential independent variables that characterize a studied phenomenon. In history-based performance prediction, the time series of observations obtained through repeated measurements over time are analyzed, and this is the approach used in this paper. Two basic prediction approaches are considered, namely classification and regression. CONCLUSION In this paper, an approach for predicting Web performance by the innovative application of the TB geostatistical simulation method was proposed. A large-scale measurement experiment was performed in the real-life Internet to gather the data characterizing performance of over 60 Web servers localized worldwide and perceived from four agents installed in different Internet locations. An unquestionable possibility of using geostatistics in a new application that is Internet network performance prediction is outlined. Such geostatistics methods have different applications, for example, spatial estimate crime rate. The comparison of spatial regression analysis (econometric models) with kriging methods indicates clearly the advantage of the former. On the basis of conducted research, the authors claim that we must work on improvement of the forecast accuracy. Web performance should be analyzed using various measurement data and prediction horizon lengths. Also, the next step should be an attempt to use other geostatistical methods which have already been successfully used by the authors to forecast loads in power transmission and distribution networks. Furthermore, we address our research approach to QoS issues in smart-grid communications technologies. REFERENCES [1] M. Ulieru and S.
