%X In underlying communication, using memory map provides user-level applications with a virtual network interface to enable user level access high speed communication devices, efficiently reduces the overhead of system protocol software and the latency in communication. In this paper, the design idea, the implementation process and the concept of communication area are discussed, by which the data can be exchanged between the kernel and user space efficiently. A sample and performance analyses are provided at last.
