Ensuring Service Level Agreements for Service Workflows
2008 IEEE International Conference on Services Computing, 2008Specifying and monitoring service level agreements (SLA) has been the subject of intensive research. However, methods of enforcing SLA have not addressed the specific issues of composite services (CS). Our work focuses on the problem of keeping prearranged SLAs for service workflows including workflows supporting long lived transactions (e.g.

Design of service level agreements for software services
Proceedings of the International Conference on Computer Systems and Technologies and Workshop for PhD Students in Computing, 2009During last years, Quality of Service (QoS) aspects in service-based applications tend to be more and more challenging issues. The paper is focused on various aspects of QoS contracts and especially on these being parts of Service Level Agreements (SLAs).

The Economics of Service Level Engineering
2011 44th Hawaii International Conference on System Sciences, 2011Today, the management of service quality poses a major challenge for many service providers and their business customers. We argue that the trade-off between service cost and benefit incurred by both parties is not sufficiently considered when service quality is stipulated.

Sustainable Service Level Agreements
2011 IEEE International Conference on Services Computing, 2011Our paper provides a method to manage sustainable service levels in call centers. We defined a service level management process and a related capacity and workforce management that considers Erlang-A operational model for staffing levels. Based on such model, we compute the minimum sustainable price for a service contract based on the fixed service ...

Service level accounting in telecommunications
NOMS 2002. IEEE/IFIP Network Operations and Management Symposium. ' Management Solutions for the New Communications World'(Cat. No.02CH37327), 2003At present, infrastructure providers generally charge for services based on the use of underlying resources. This paper describes a means of accounting for services at the service level, then outlines an architecture that supports such a means of accounting and evaluates an implementation based on that architecture.

Service Levels, Security, and Trust
2012This chapter covers the scientific background for the Service Level Module of the Unified Service Description Language (USDL). In addition to general service level concepts, we expand on two specific service level fields: security and trust. For that end we first review the state of the art in service level modeling, then we explain the design of the ...

Levels of Quality of Service in CINEMA
1995Distributed multimedia systems require quality of service at various abstraction levels. At the application level, QoS describes communication in terms of application specific processing units, e.g. frames. At the transport level QoS is used to describe the communication load for the transport system.

Service Level Semantic Interoperability
2010 10th IEEE/IPSJ International Symposium on Applications and the Internet, 2010Interoperability is a collaborative and multifaceted task to overcome the problems of incompatibilities among organizations, structures, data, architecture, services, and business rules. To achieve interoperability, the aspect for interoperability and requirements for applications and services must be known.
