| Abstract | Network topology information has many uses for networked applications including the design of reliability and performance enhancing schemes. This information is often acquired by network discovery techniques that rely on ICMP and/or SNMP support from the infrastructure. Unfortunately, network infrastructure may support such services at varying levels. In cases where such support is limited, techniques based on strictly end-to-end measurements have been proposed in the literature to infer a logical topology. In this paper, we propose an end-to-end measurement technique that is complimentary to the earlier techniques and relies on multiple-source multiple-destination probing to collect network wide measurements faster. Our technique relies on the interaction between streams of packets at various nodes in the network. Specifically, we aim to measure the reaction of end-to-end probes to a short burst of concentrated traffic (signal) injected to the network. The key assumption is that probes traversing paths that physically intersect with the path of the bursty traffic (signal path) will exhibit extra jitter. The occurrence of extra jitter in the probe packet inter-arrival times matching the signal bursts indicates that the paths of the probe and signal intersect. We conducted an empirical study on an actual production network to evaluate the ability of the technique to detect end-to-end path intersections. Our empirical results indicate that in the network we considered the technique successfully detected path intersections. |

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.
