| Abstract | Traffic matrix (TM) is constructed by all origin-destination (OD) pairs (or flows) in a network, which describes the characteristics of IP networks from the global aspects. Though TM estimation is well-studied, TM is generally unavailable in a large-scale IP network and is difficult to be estimated accurately. This paper proposes a novel method of large-scale IP TM estimation, based on simulated annealing, termed the Simulated Annealing and Iterative Proportional Fitting Procedure (SAIPFP) method. Firstly, based on conventional simulated annealing, we propose a modified simulated annealing method, which considers sufficiently spatial-temporal correlations of OD flows and is combined with partial flow measurement. By the modified method, we can attain good estimations of TM. Secondly, combined with iterative proportional fitting procedure, the more accurate estimations are attained. Finally, we use the real data from the Abilene network to validate our method. The results show that our method can perform quickly the accurate estimation of large-scale IP TM, and track well its dynamics. |

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.
