| Abstract | Live migration of virtual machines(VMs) is widely used for system management in virtualized servers. When the loads increase and SLAs of some applications are violated, dynamic migration of virtual machines across physical machines (PMs) has the potential to ensure a high level of meeting the SLAs. Because of consuming extra CPU and bandwidth, application performance may be degraded during the migration process. However, different applications have different performance degradation. We design and implement a VM migration selection method that decides which VMs should be migrated. It can not only eliminate resouce competition on the PM, but also have less performance degradation during the migration process. We propose a performance degration-aware model to analyze applications' performance degradation which is directly sensitive to users. We analyze migration source code and find that memory size, dirty rate and frequent dirty rate are key factors that affect iteration time and downtime. We implement a tool that measures dirty rate and frequent dirty rate before VMs are migrated. we make a distinction between memory iteration phrase and stop-and-copy phrase owing to different performance degradation. The experimental results show that our method is effective. |

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.
