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.

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.

The role of service level agreements in IT service delivery
Information Management & Computer Security, 1998Introduces the concept of service level agreements (SLAs) in IT service provision, especially in the case of outsourced service provision. Reports the experience of several consulting engagements and surveys to substantiate suggested frameworks and checklists. Discusses the reasons for exercising rigour around SLAs.

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 ...

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 Level Agreement Enforcement for Differentiated Services
2006This paper describes a hierarchical architecture of active policies that performs the management of a differentiated services (DiffServ) network. These policies monitor quality of service (QoS) parameters and dynamically optimize some aspects of the existing equipment and services to provide the best possible QoS to users. This helps the enforcement of

Service Adaptation at Message Level
2011 IEEE World Congress on Services, 2011In SOA, adaptation techniques aim to automatically generate adapters. However, the generation of the adapter is a complicated task and requires extra knowledge to resolve all kinds of mismatches. We propose a novel model, called a protocol structure, which is used to model services and adapters and detect the mismatches among services.

Adaptive Service Level Management
11th IEEE International Enterprise Distributed Object Computing Conference (EDOC 2007), 2007In the aerospace industry, it is not unusual for an IT infrastructure, which consists of hundreds of applications, thousands of computers, and massive data storage, to serve only a single program. The quality requirement of services varies from time to time and ensuring the quality of services becomes extremely challenging. The difficulty is compounded

Proceedings of the 8th international conference on Electronic commerce The new e-commerce: innovations for conquering current barriers, obstacles and limitations to conducting successful business on the internet - ICEC '06, 2006
This paper describes an ontology based Service Level Agreement formalisation. OWL and SWRL are chosen to express the ontologies. Use of the ontologies, discussing Ontology Adoption, SLA Instance Creation and Validation is given, followed by a breakdown and discussion of the concepts. Ontologies are grouped by generality and diagrammatic representations

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.
