摘要
附网光盘刻录设备兼具网络存储和光存储的优点,提供方便的低成本远程数据备份,并且具有良好的扩充性,但基于分组交换原理的网络数据流量的不稳定直接威胁光盘刻录设备的运行品质.通过排队理论分析和数学模型仿真,定量地研究了在不同的网络负载环境下,附网光盘刻录设备的Cache容量及使用策略对其运行品质的影响,最后针对不同的使用环境,提出了具体的提高附网光盘刻录设备运行品质参数的方法.
The network-attached optical disk storage device has the advantages of the network-attached storage device and the optical storage device, can be used in remote data backup and expanded easily. But the running quality of the network-attached optical disc device is threatened by the unstable data stream in the networks based on packet switch theory. This paper quantitatively analyzes the effect of the cache capacity and strategy of the network-attached optical disk storage device on the running quality of the device by using queuing theory and simulating method, and finally gives practical methods to optimize the running quality parameters of the the network-attached optical disk storage device in different environments.
