In this paper, in order to manage both computing and network resources effectively in optical grid networks, we propose a dynamic management method which is implemented in a job manager. The proposed method adjusts the number of tasks which are transmitted to a computing site with PID control so that a resource manager can store a constant number of tasks, resulting in an effective utilization of computing resources. Moreover, lightpaths are established and released dynamically by comparing output signal of PID controller with the maximum number of transmitted tasks, resulting in an effective utilization of network resources. We evaluate the performance of the proposed method, and then we investigate the impact of PID parameters. In numerical examples, we show that the proposed method can manage computing and network resources at the same time more effectively than a conventional method.
