| Abstract | Summary form only given. High-speed networks are becoming popular for accessing remote data and information sharing and more and more organizations are connecting through networks to obtain financial and strategic advantages. However, this high-bandwidth connectivity also exposes them to a higher degree of security attacks and intrusions. A router-based packet-filtering firewall is an effective way to protect an enterprise network from unauthorized accesses. However, traditional firewalls will not work efficiently in ATM networks because they require termination of end-to-end connections at the packet-filtering router for packet inspection. This is likely to incur a high overhead due to packet segmentation and reassembly making it a serious bottleneck. This talk presents the design of a high-speed ATM firewall that does not require the termination of an end-to-end connection in the middle. This firewall switch nicely integrates the IP level security mechanisms into the hardware components of an ATM switch so that most of the filtering operations are performed in parallel with the normal cell processing and most of its cost is absorbed into the base cost of the switch. The firewall switch employs "last cell hostage" (LCH) to avoid or reduce the latency caused by filtering. We analyze in detail the performance of the firewall switch in terms of the throughput and latency. |

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.
