| Abstract | A prototype platform has been developed that allows processing of packets at the edge of a multi-gigabit-per-second network switch. This system, the Field Programmable Port Extender (FPX), enables packet processing functions to be implemented as modular components in reprogrammable hardware. All logic on the on the FPX is implemented in two Field Programmable Gate Arrays (FPGAs). Packet processing functions in the system are implemented as dynamically-loadable modules.Core functionality of the FPX is implemented on an FPGA called the Networking Interface Device (NID). The NID contains the logic to transmit and receive packets over a network, dynamically reprogram hardware modules, and route individual traffic flows. A full, non-blocking, switch is implemented on the NID to route packets between the networking interfaces and the modular components. Modular components of the FPX are implemented on a second FPGA called the Reprogrammable Application Device (RAD). Modules are loaded onto the RAD via reconfiguration and/or partial partial reconfiguration of the FPGA.Through the combination of the NID and the RAD, the FPX can individually reconfigure the packet processing functionality for one set of traffic flows, while the rest of the system continues to operate. The platform simplifies the development and deployment of new hardware-accelerated packet processing circuits. The modular nature of the system allows an active router to migrate functionality from softare plugins to hardware modules. |

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.
