Analysis and Research of Caching Mechanism of Cluster File System

In this paper,aiming at the existed problems in traditional caching system structure with three layers, the authors present the cooperative caching mechanism so as to obtain the coordination and full use of caching resources at each node in the system, thus further, raise the efficiency of the document interview, prevent the document server from becoming the system bottle-neck which affects the efficiency of the document system; brief analysis of several familiar algorithms about management of cooperative caching is given.
