SLA Negotiation Protocol for Grid-Based Workflows
نویسندگان
چکیده
Service Level Agreements (SLAs) are currently one of the major research topics in Grid Computing. SLA negotiation protocols define a business relationship between consumer and provider and are thus a necessary part of any commercial Grid application. In the Grid environment, an SLA negotiation protocol for a workflow becomes complicated because of its structure which includes many dependent sub-jobs. The complex workflow model leads to several constraints compared with the case of single jobs and requires advanced solutions. As a continuous effort in building a full system supporting SLA for Grid workflows, this paper presents a SLA negotiation protocol for workflows and the initial system implementation.

Towards a Meta-Negotiation Architecture for SLA-Aware Grid Services
In novel market-oriented resource sharing models resource consumers pay for the resource usage and expect that non-functional requirements for the application execution, termed as Quality of Service (QoS), are satisfied. QoS is negotiated between two parties following the specific negotiation protocols and is recorded using Service Level Agreements (SLAs) standard. However, most of the existing...
متن کاملA Multi-agent Infrastructure and a Service Level Agreement Negotiation Protocol for Robust Scheduling in Grid Computing
In this paper we propose a new infrastructure for efficient job scheduling on the Grid using multi-agent systems and a Service Level Agreement (SLA) negotiation protocol based on the 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 scheduler agents sche...

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...
متن کاملPerformance Evaluation of a SLA Negotiation Control Protocol for Grid Networks
A framework for an autonomous negotiation control protocol for service delivery is crucial to enable the support of heterogeneous service level agreements (SLAs) that will exist in distributed environments. We have first given a gist of our augmented service negotiation protocol to support distinct service elements. The augmentations also encompass related composition of the services and negoti...
متن کاملA Negotiation Mechanism for Advance Resource Reservation using the Alternate Offers Protocol
Service Level Agreements (SLAs) between grid users and providers have been proposed as mechanisms for ensuring that the users’ Quality of Service (QoS) requirements are met, and that the provider is able to realise utility from its infrastructure. This paper presents a bilateral protocol for SLA negotiation using the Alternate Offers mechanism wherein a party is able to respond to an offer by m...
