| Abstract | Traffic grooming technique in an optical network economizes costly optical resource, or the wavelength channels, by sharing it between sub-wavelength granularity flows. For a higher wavelength channel utilization ratio, a traffic grooming solution often finds longer detour paths to provision a flow. The longer traversing of a flow cause higher propagation delay. In case of delay-critical applications, one might be even willing to pay more power cost for low delay. In this paper we propose a heuristic traffic grooming algorithm for balancing between power and delay in a typical IP-over-WDM network. The suggested heuristic benefits a power consumption savings as much as a conventional power-aware heuristic algorithm. Additionally, it achieves a shorter delay by giving a high priority to the short physical distance flow when route. In comparison to the previous studies of the power-aware traffic grooming heuristic, we investigate both power and delay performances with our heuristic algorithm. |

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.
