| Abstract | The Locator/ID Separation Protocol (LISP) is being standardized in IETF, which separates the IP address functionality into routing locators (RLOC) and endpoint identifiers (EID). LISP is applicable for instant Virtual Private Network (VPN) services because it has IP tunneling features. However, there are two main issues with application to VPN. One is a Map server/Map resolver (MS/MR) basically allows any third party to know a mapping table even if it is irrelevant to the VPN. The other is an MS/MR should identify the VPN to which the requested site belongs because the requested EIDs can be private addresses and may overlap with other VPN sites. A simple solution is to deploy an independent MS/MR for every VPN. However, this is undesirable from a cost perspective. We present a new LISP-MS/MR that provides a large number of VPN services using a single set. This MS/MR creates a logically separated EID-to-RLOC mapping table for each VPN and selects an appropriate type according to the requesting VPN site. To ensure this, our scheme uses Authentication data included in the Map register for an initial VPN identification of the registering site and associates the identified VPN ID with the registered RLOC. In following Map requests, the appropriate mapping table for the requesting VPN site is selected based on its RLOC. We confirmed the basic network functions of VPN using the prototype system. The results of scalability tests show that our MS/MR completes the transaction for nearly-simultaneous 10,000 Map registers or requests within three seconds. |

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.
