In this paper we propose a new infrastructure for efficient job scheduling on the Grid using multiagent systems and a market-like Service Level Agreement (SLA) negotiation protocol based on the well known Contract Net Protocol. The agent-based Grid scheduling system involves user agents, local scheduler agents, and super scheduler agents. User agents submit jobs to Grid Compute resources. Local...

As the contents of multimedia proliferate, the higher level of network speed is needed to the customer. SLA is a negotiated agreement between a customer and the service provider on levels of service characteristics and the associated set of metrics. In this paper, we propose an SLA management system reacting not only when an SLA is violated, but also before imminent SLA violations. We provides ...

SLA is a negotiated agreement between a customer and the service provider on levels of service characteristics and the associated set of metrics. In this paper, we propose a policy-based SLA management system. We present an approach to react not only when an SLA is violated, but also before imminent SLA violations. We provide a common generic framework capable of components to interwork via XML...

Federated computing environments offer requestors the ability to dynamically invoke services offered by collaborating providers in the virtual service network. Without an efficient resource management that includes Dynamic SLA Negotiation, however, the assignment of providers to customer’s requests cannot be optimized and cannot offer high reliability without relevant SLA guarantees. We propose...

It is imperative for a competitive e-business outsourcing service provider to manage the execution of its service level agreement (SLA) contracts in business terms (e.g., minimizing financial penalties for service-level violations, maximizing service-level measurement based customer satisfaction metrics, etc.). In order to do that, the provider must possess a generic means of capturing and mana...

Service-level agreements (SLA) are essential for IT service management due to the complexity of IT service delivery model and the importance of ensured Quality of Service (QoS) for corporate clients. This study proposes a novel geometric framework for analyzing the optimal pricing and capacity planning for IT service provider under SLA. The IT service with congestion costs is modeled using an M...

Mobile applications and mobile application environment of next generation networks require enhanced quality of service (QoS) to support user’s service level agreement (SLA). This paper presents an adaptation technique at transport layer to minimize the impact of varying and adverse network condition along with security and priority to satisfy the SLA. The paper extends the transport layer funct...
