| Abstract | The exhaustion of the IPv4 address space significantly increases the urgency for transitions to IPv6. Since native IPv6 support is not yet ubiquitous, a major concern of users and service providers (e.g., Facebook, Google, etc.) is that end-to-end performance via IPv6 could be substantially worse than IPv4. In this paper, we develop an analysis method and framework that matches DNS rendezvous information to flows so that we can compare and contrast performance over both protocols for a variety of Internet services. Our initial analyses focus on the basic services that are accessed using both protocols, observed client behaviors, and a presentation of performance characteristics of services using both IPv4 and IPv6. Our objective is to detect and expose differences by passive measurement without access to application traffic payloads. To demonstrate our method, we present results of an empirical feasibility study that considers the issue of Internet services performance over IPv6. Our study uses data collected on the World IPv6 Day, including both DNS requests/responses and flow export records for dual-stack hosts operating at a large research university. Our results expose various performance characteristics of Internet services that support IPv6: (1) Robust measures of services' flow bit rate distributions vary significantly by time of day, by number of active local clients, and by IP protocol version (6 or 4). (2) These rate characteristics differ amongst services. (3) There are regimes of time in which IPv6 flow bit rates exceed those of IPv4 and others where the IPv4 flow rates exceed those of IPv6. |

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.
