| Abstract | A lot of transition mechanisms have been proposed and standardized in Internet Engineering Task Force (IETF), to support the coexistence and interoperability of IPv4 and IPv6. Among them, the 4over6/6over4 edge network tunneling technique has become a particular hot subject recently. To apply this technique into real ISP networks, there is a practical problem: planning the placement of the tunnel concentrators and the routing of the tunneling flows. The problem is essential to the performance and efficiency of data transport in IPv4-IPv6 coexisting network. As the first effort to address this problem, this paper formalizes the problem and builds the optimization model. It proves the problem to be NP-complete and locates the difficulties in the variable diversity and the hub and unsplittable flow features. A novel scheme is then proposed to find an approximate solution. The scheme decomposes the problem and explores the flow routing variability. It eliminates the hub feature by sophisticated topology transformation, and solves the min-cost unsplittable flow problem by shortest path routing of each individual flow along with minimum-interference to other flows. With acceptable time efficiency, the scheme finds better solutions than greedy algorithm and former minimum-interference routing algorithms in most cases. |

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.
