| Abstract | We present Sourcey, a new data center network architecture with extremely simple switches. Sourcey switches have no CPUs, no software, no forwarding tables, no state, and require no switch configuration. Sourcey pushes all control plane functions to servers. A Sourcey switch supports only source-based routing. Each packet contains a path through the network. At each hop, a Sourcey switch pops the top label on the path stack and uses the label value as the switch output port number. The major technical challenge for Sourcey is to discover and monitor the network with server-only mechanisms. We design novel algorithms that use only end-to-end measurements to efficiently discover network topology and detect failures. Sourcey explores an extreme point in the design space. It advances the concept of software-defined networking by pushing almost all network functionality to servers and making switches much simpler than before, even simpler than OpenFlow switches. It is a thought experiment to show that it is possible to build a simple data center network and seeks to raise discussion in the community on whether or not current approaches to building data center networks warrant the complexity. |

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.
