This paper introduces a reliability conscious Service Level Agreement (SLA) based admission controller for data networks. Previous research on optimal SLA admission control is discussed, especially the modeling of the admission control problem as a type of Knapsack problem and control architectures developed on this principle. To provide provisions for reliability, the basic SLA specifying a us...

Service orientated architectures (SOA will support a dynamic market in commodity services and enable business to drive down costs and respond faster and flexibly to changing markets. Virtualisation delivers similar benefits for the management of resources. If viable business models for the combination of these two technologies can be found, a true commodity grid can become reality. An essential...

Federation of Cloud services is notably landing interests from both Cloud providers and consumers. Cloud providers nowadays are required to form federations to remain competitive, and sustain their market share. Cloud consumers however seek optimized services from Clouds federation. They strive to maximize their satisfaction level, which is often measured by Quality of Service (QoS). Federation...

Cloud Service Providers offer access to hardware and software resources across the Internet. Cloud Service Providers and their clients negotiate Service Level Agreements (SLA) that specify terms and conditions of services. To ensure that an SLA is being honored by all parties the service is monitored. This paper proposes a monitoring approach that automatically adapts the monitoring process in ...

Background: Hephaestin is a multicopper ferroxidase required for basolateral transport of iron from enterocytes. Sex linked anaemia (sla) mice have a defect in the release of iron from intestinal enterocytes into the circulation due to an interstitial deletion in the hephaestin gene (heph). Results: We have demonstrated that hephaestin is primarily localised to a supranuclear compartment in bot...

We illustrate a process for nding an improved variant of an aboriginal whaling management procedure strike limit algorithm (SLA), applying the merging and opti-misation approach of Givens (1997; 1999a). A modiied version of the SLA developed by Punt and Butterworth (1997) was chosen as the procedure to be optimised for management of the Bering-Chukchi-Beaufort Seas stock of bowhead whales. The ...

A Service Level Agreement (SLA) represents an agreement between a service user and a provider in the context of a particular service provision. SLAs contain Quality of Service properties that must be maintained by a provider. These are generally defined as a set of Service Level Objectives (SLOs). These properties need to be measurable and must be monitored during the provision of the service t...

In the business Grid environment, the business relationship between a customer and a service provider should be clearly defined. The responsibility of each partner can be stated in the so-called Service Level Agreement (SLA). In the context of SLA-based workflows, the business model is an important factor to determine its job-resource-mapping policy. However, this aspect has not been described ...
