Performance Evaluation for the GI/GI/1 Round-Robin System

Abstract (in Japanese) (See Japanese page) 
(in English) The round-robin (RR) scheduling algorithm is one of the widely used operating system scheduling algorithms for information processing systems. According to RR scheduling algorithm, the processor allocates to each job a fixed amount of time, called a quantum. If a job’s service time (the total time required from the processor) is completed in less than the quantum, it leaves; otherwise, if feeds back to the end of the queue of waiting jobs, waits its turn to receive another quantum of service, and continues in this fashion until its total service time has been obtained from the processor. Kleinrock presented the M/M/1 (RR) model, and studied this model in the limiting case where the quantum length goes to zero. The limiting case model is called as processor-sharing (PS). There has been much literature on the single-server (PS) models. However, most of them treated only the Poisson-arrival M/G/1 (PS) models. The main purpose of this paper is to present an analysis of a general input GI/GI/1 (RR) model which generalizes the previously analyzed M/GI/1 (RR, PS) models. Our approach is based on the sample-path analysis together with the diffusion process approximation technique. The accuracy of our proposed formulae on the mean performance measures is validated by computer simulation results.
