摘要
数字化浪潮带来了海量的数据,全球正在迈入网络存储时代。NFS作为最常用的协议之一,默认基于同步UDP,因此无法实现流量控制,导致在大负载的网络存储系统中出现性能障碍。本文根据机载存储需求,选择稳定而且可靠的VxWorks实时操作系统环境,分析了NFS协议的特点,以排队论为思想基础,设计并实现了对于NFS协议的优化。
Vast amounts of data appear with the digital wave,the world is entering an era of network storage.NFS(Network File System) is one of the most common protocols used nowadays.But the default setting of NFS is based on SYN UDP,which cannot achieve traffic control during communication and easily results in performance barriers in a heavy-loading network storage system.According to the demand of airborne storage,this paper analyzes the NFS protocol on a stable and reliable real time operating system-VxWorks,and design optimization for the NFS protocol based on queuing theory.
