Service Level Agreements (SLAs) are currently one of the major research topics in Grid Computing. Among many system components for supporting of SLA-aware Grid jobs, the SLA mapping mechanism receives important positions. It is responsible for assigning sub-jobs of the workflow to Grid resource in a way that meet the user's deadline and as cheap as possible. With the distinguished workload and resource characteristics, mapping a heavy communication workflow within SLA context defines an unfamiliar problem and need a specific method to be solved. This paper presents the mapping algorithm, which can cope with the problem. Performance measurements deliver evaluation results on the quality and efficiency of the method.
