| Abstract | Content Centric Networking (CCN) Architecture has been suggested to overcome weaknesses of current Internet architecture. This architecture is based on the concept of decoupling data from location and retrieving contents by name instead of location. Transport layer protocol i.e. CCNx has been proposed for use with CCN. CCNx performs longest prefix match between requested content name and entries stored in Forwarding Information Base (FIB) table of CCN router. A request is discarded if no match is found between them. CCN routers will be required to maintain a large number of entries in FIB table due to shifting of address space from one billion IPs to at least one trillion content names. Currently, CCN routers cannot store mapping for all content names in FIB table. This will cause large number of FIB's misses and can lead to deadlock situation despite the fact that requested content might be held by a nearby router. In this paper, we have accessed suitability of using different alternatives of blind routing algorithms as a fall back scheme for CCNx when FIB miss occurs. We have implemented different blind routing algorithms i.e. flooding, expanding ring and random walk over CCNx in an OPNET simulator using C language. Matrices of routing overhead, end-to-end delay and success rate have been used for making comparisons. Our results suggest that random walk with queries sent on half of the total links can be used as fall back scheme to avoid deadlock problem. To the best of our knowledge, this is the first time that a simulation study of blind routing algorithms over CCNx architecture has been carried out. |

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.
