Abstract: CA-NFS meets the requirement of the QoS of NFS for different applications by delaying or accelerating the application of the file operations. It achieves good performance. However, it does not consider the impaction of the network delay jitter of NFS packets. This paper designs and implements a module for managing QoS, offers the guarantee ablility for the QoS of NFS with less cost by exploiting the existing mechanisms of CGroup and QoS of Linux. From the experimental results, the improved NFS reduces the range of delay jitter of network packets. Its performances better than before. It provides a certain of capability for assuring the QoS of NFS.

Key words: network file system, network storage, quality of service
