A bilateral negotiation mechanism for SLA-based job superscheduling in Grid-Federation

摘要

SLA-based job scheduling and resource allocation are based on the concept of agreement between supplier and consumer, and negotiation is the first step in establishing a service level agreement (SLA) between two participants. This article presents a bilateral negotiation protocol using the alternate offers model for scheduling and resource allocation in Grid-Federation. This method with considering the user's and resources owner's criteria aims to meet the users' quality of service (QoS) requirements and improves job migration conditions as well as realizes utility for the resource owners. Our simulations on GridSim toolkit explain the usefulness of this approach in providing QoS to users and its impact on superscheduling in Grid-Federation.
