| Abstract | The TACOMA system [JRS95] provides operating-system support for mobile processes, or agents, that traverse the hosts of a network in accomplishing some task. A TACOMA agent executing on one host moves to another host by using TCP to communicate with TACOMA software at the destination host. The presumption is that TACOMA software has been installed at any host that might launch or be visited by an agent. This presumption is questionable:• System managers are reluctant to install software that allows arbitrary imported software, like agents, to be executed on their hosts. And, there is good reason for this reluctance.• Hosts are autonomous. So, even were security not a concern, arranging for installation of a piece of non-critical software on a significant fraction of the hosts in a large network is impractical.The network-software installation-problem is not unique to agents or to TACOMA. Any provider of software will be faced with this problem if that software must be installed on autonomous sites of a large network. The speed with which WWW software spread through the Internet was an exception; architects of distributed-application support-software should not plan on having their systems disseminated in such a fashion. But, these architects better have some plan for disseminating their systems, since the utility and success of large networks will depend on offering new services in a timely way.This paper reports experiences in addressing the network-software installation-problem for TACOMA. However, we believe that the techniques employed have utility in other situations as well. The next section gives an overview of TACOMA and the applications it currently supports. Section 3 describes a WWW-based scheme for avoiding software installation at all sites that might launch TACOMA agents; section 4 discusses an email-based scheme. Section 5 concludes with a summary and some observations. |

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.
