| Abstract | The Internet is on the way of becoming the universal communication network, and then needs to provide various services with guaranteed quality for all kinds of applications. Denial of service (DoS) attacks are then more efficient in a guaranteed multi-services network than in the "old" best effort Internet. Indeed, with best effort services, a DoS attack has to forbid the target of the attack to communicate. With a multi-services network, it is sufficient to make the network not respect the SLA (service level agreement) committed with clients, what is easier and can be performed using simple flooding attacks. Then, the question is: how does a DoS attack impact the quality of service (QoS) of a network given that networks are hugely over-provisioned, and that DoS attacks never succeed to completely overflow these high speed networks? This paper aims at answering this question as we do believe that it can help for defending the network against such attacks. The analysis of DoS attacks has been performed using traffic monitoring tools on the Internet. In particular, the analysis of attacks shows that they are increasing long range dependence (LRD) in the traffic, breaking the invariant power laws of normal Internet traffic. It is also explained in the paper, based on some normal traffic traces characterization and analysis why LRD is such a bad parameter for having good QoS. |

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.
