| Abstract | Summary form only given. The continuous growth of the routing tables sizes in backbone routers is one of the most compelling scaling problems affecting the Internet. Beside the deriving waste of memory, the main problem posed by this phenomena is a general increase of the tables lookup time during the routing of the IP datagrams. Thus, a considerable research effort has been devoted in the design of algorithms for fast lookups and for compressing existing tables. However, the envisaged close enhancement of the current version of the IP protocol to IPv6 and the introduction of the so called network address translators (NATs) urgently require the solution of the IP routing tables minimization problem in a new and more effective way, that is by performing addresses reassignments. In such a setting, we first give an algorithm with an asymptotically optimal running time that assigns addresses so as to minimize the size of a single routing table. We then show that minimizing the sum of the sizes of n routing tables is an intractable problem, i.e. NP-hard, and present a 3h-approximation algorithm, where h is the length of the IP addresses. |

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.
