| Abstract | This paper presents a call-level traffic analysis and characterization, based on real data collected from a VoIP service provider, for a time period of almost one year. This traffic includes calls within the VoIP network boundaries and others that are either initiated or terminated by other telephone networks, since most contemporary VoIP networks interconnect with other landline or cellular telephony networks. The traffic is originated by a multitude of user profiles. However on the calllevel basis, it can be described basically by two main processes, namely the Call Arrival and the Call Duration. Hence the aim of this work is the examination of the call arrival pattern and the extraction of a statistical distribution that can accurately describe this type of traffic. Also the call-duration times are analyzed to obtain the corresponding distribution. Hence, the contribution of the work is twofold. Firstly the data of a reallife VoIP network is examined for a long time-period which is independent from traffic patterns that occur within certain time periods or caused by events such as holidays and summer vacations. Secondly, the same data is differentiated based on the user behaviour in different time periods, such as working hours and weekends and the extracted results show differences between the statistical behaviour of the traffic. The presented results differ from other existing work and can be utilized to allocate resources more efficiently, to appropriately handle the network's traffic, to configure VoIP simulations in a more realistic way and to enhance the management of such networks. |

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.
