| Abstract | IPv4 addresses are nearly exhausted worldwide. For some time until IPv6 becomes pervasive as an ultimate solution, deployment of Carrier Grade NAT (CGN) devices becomes necessary, especially in the mobile carriers' networks which anticipate a large and growing number of new users. In this context, we tackle the evaluation of the impact of inserting a CGN device in the network, and in conjunction with the mobile network communication delays. We compare the Connection Establishment Rate (CER) with or without a CGN device, also with or without the emulated mobile network communication delays. Against our anticipation, the types of time-varying mobile network delays do not have a significant impact on CER. The effect of the changing delay fades away in the aggregation of many user traffic at the core part of the network, even though the time-varying mobile network communication delays are individually and separately emulated for each user. To the best of our knowledge, this is the first to study the relationship between the CGN performance and the mobile network's communication delays. The result suggests that modeling the aggregate traffic trend (such as the constant delay portion in the network dynamics) is more important rather than emulating each user's traffic separately. |

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.
