Congestion-aware burst control algorithm for OBS networks

Abstract

By taking advantage of statistical multiplexing in the burst level, Optical Burst Switching (OBS) technology enables optical internet to handle huge volume of data in an efficient manner without requiring optical memories in the optical domain. However, when the congestion is built in the optical network core, large amount of data can be lost. In this paper, we propose an efficient burst control algorithm, which operates based on the awareness on future traffic condition. Through the performance analysis, it is verified that the proposed algorithm effectively decreases the burst loss while maintaining high throughput as compared to the burst control algorithm based on current information.
