| Abstract | Networks are becoming increasingly complex and service providers incorporate additional functionality in the network to protect, manage and improve service performance. Software Defined Networking (SDN) seeks to manage the network with the help of a (logically) centralized control plane. We observe that current SDN solutions pre-translate policy (what) into forwarding rules at specific switches (where). We argue that this choice limits the dynamicity, flexibility and reliability that a software based network could provide. Information Centric Networking (ICN) shifts the focus of networks away from being predominantly location oriented communication environments. We believe ICN can significantly improve the flexibility for network management. In this paper, we focus on one of the problems of network management -- service chaining -- the steering of flows through the different network functions needed, before it is delivered to the destination. We propose Function-Centric Service Chaining (FCSC), a solution that exploits ICN to provide flexibility in managing networks that utilize virtualization to dynamically place functions in the network as required. We use a real-world topology to compare the performance of FCSC and a more ``traditional'' SDN solution. We show that FCSC reacts to failures with fewer packet drops, adapts to new middleboxes more quickly, and maintains less state in the network. |

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.
