A New QoS Guaranteed Mechanism Based on SLA in Grid Market

As the key character of grid is the good service quality, the study of QoS (quality of services) becomes more and more important. And SLA (service level agreement) can really guarantee the QoS. Although SLA has been a topic in the field of telecom for many years, the researches of it in the grid are still not perfect, especially in the emerging grid economy field. In this paper, we propose a SLA control module (SCM), for the grid architecture for computational economy (GRACE), and give a detailed introduction of the internal structure of the SCM. Additionally, a local SLA driven algorithm was designed based on it in the grid economy for good service quality. At last, we show the performance of the system by simulating experiments.
