Abstract

The invention discloses an airborne network file system, which comprises server side NFS software deployed on nodes with mass storage and client side NFS software deployed on other nodes, the client side NFS software adapts different operating systems and buses, an NFS interface is registered to a local operating system IO, and the server side NFS software and the client side NFS software are connected with the client side NFS software. Mapping a server-side storage directory into client-side local storage equipment, packaging a request data frame, then sending the request data frame through a bus, and analyzing a response data frame received on the bus; and the server NFS software carries out task resource management and node resource management on the client, carries out node mounting and node unloading on the client, adapts different operating systems and buses, analyzes request data frames received on the buses, encapsulates response data frames and sends the response data frames through the buses. According to the invention, the client node can obtain high-speed large-capacity storage resources under different operating system platforms without designing own storage resources.
