The communication performance is an important fac tor of the performance in cluster computer, which must be considered for the challenge that tries to improve its over all performance to accomplish the desired one. This pa per focuses on the communication method for reducing the communication data in cluster computer using a data com pression mechanism based on software in the link layer of cluster network, called the link layer compression. The technique is implemented on a lower layer of the clus ter network comparatively to the mechanisms proposed in the preceding researches. Finally, the performance results show that the technique is able to enhance the performance of cluster computer, as well as achieve good compatibility for cluster-oriented applications.
