| Abstract | "Fractal" analysis of computer network traffic has been the subject of various studies. Most of the effort has been concentrated on measuring and modeling a possible long range dependence (LRD) process of the traffic trace. However, long range dependence is only one feature of the "fractal" behavior. In this paper, we study rather different properties which are conveniently described by using multifractal analysis. After a basic introduction to the definition of self-similar and multifractal process in traffic modeling, we use parsimonious traffic traces to examine the effectiveness of multifractal traffic modeling. Some MPEG-1 coded traces and TCP packets monitored at CERNET are used to give the statistical evidence of the multifractal nature through coarse grain. We find that using only the Hurst index in the self-similar approach is not enough to capture the burstiness in both small and large time scales while the Holder exponent provides insight into the bursty nature of the traffic sources. We propose a multiwindow wavelet transform method for the purpose of estimating the time varying scaling Holder exponent. Numerical results are also given to show the accuracy of multifractal modeling using real traffic traces. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
