Scaling up SLA monitoring in pervasive environments

Content Provider ACM Digital Library
Author De Angelis, Guglielmo Elbaum, Sebastian Bertolino, Antonia Sabetta, Antonino
Abstract Service level agreements (SLA) are contracts defining the obligations and rights between the provider of a web service and a client with respect to the service's quality. An essential component of SLA management is the run-time checking of relevant quality parameters. SLA checking must be precise and continuous to timely detect any possible SLA violations. Available techniques and mechanisms to check SLAs, however, are unlikely to scale to more complex families of SLAs tailored to fit diverse and very large groups of clients whose devices have limited storage and bandwidth capabilities. This challenge results not only in the commitment of valuable resources to SLA checking (reducing the service provider capacity), but it can also trigger additional violations and cause disagreements between client and server due to perceived violations. In this paper we focus on the elaboration of this challenge and on identifying opportunities that arise from the inherent diversity present in scenarios rendering web services in pervasive environments.

About National Digital Library of India (NDLI)
NDLI logo

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.
