【Abstract】 A virtual network storage system based on WDM is designed.The virtual layer running in the kernel mode completes the mapping of the local disk operation to the net communication on the block device level.So the running priority of the system can be guaranteed.The reliability and real-time accuracy of the network communication can be improved greatly.Storage devices in the system can provide the uniform and transparent interface for the user.The architecture and specific implementation are introduced.更多还原
