| Abstract | The scalability of the global routing system is critical for the evolution of the Internet, and consequently, BGP scalability has been part of the Internet research agenda from long ago. The original concern was the growth of the routing table size, and more recently, the research community has also been considering the growth of the BGP churn, i.e. the number of messages that are generated by the BGP protocol. Some relevant studies have characterized the evolution of the external BGP (eBGP) churn for the last few years and have shown a moderated increase. There is evidence that part of such growth is caused by important changes in inter-AS connectivity patterns, along with some unexpected behaviour of internal BGP (iBGP), in particular, intra-AS duplication of BGP updates due to Route Reflectors (RR). There are many vantage points in the Internet that record BGP traces, which permit to study eBGP behaviour, but there exist no public iBGP traces nor internal AS topology repositories, limiting the exploration of iBGP influence in the global scalability problem. In this paper we analyse route reflection benefits and caveats, and present RRLOC, an Open Source tool developed to facilitate research on this matter. The tool supports the location of Route Reflectors in a given AS topology using well-known algorithms, enabling the experimentation on iBGP dynamics, with the aid of network simulators. It also allows network planners to test different scenarios for RR placement. |

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.
