Abstract | Accurate and fast identification of network traffic is an important element of many network management tasks such as QoS provisioning and security monitoring. However, as many newly-emerged Peer-to-Peer (P2P) applications using dynamic port numbers, masquerading techniques, and payload encryption to avoid detection, the classical approaches based on port mapping and payload analysis are ineffective. An alternative approach is to classify traffic by distinguishing the behavior of an application within the first few packets of TCP connection. We pursue this approach and demonstrate that information of few packets is enough to effectively identify P2P traffic. In our work, C4.5 decision tree and REPTree are evaluated and compared with the previously used clustering method K-Means. Experimental results show that our approaches outperform K- Means algorithm in accuracy. In addition, the proposed approaches can accommodate known and unknown P2P traffic and even encrypted traffic in fast and accurate way, which ensures the real-time applications on the Internet traffic surveillance and QoS provisioning. |

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.
