Through modifying the network device driver of Linux device driver 3rd version snull.c and improving the COW technology,the Zero-Copy technology in Linux (kernel version 2.6.11) is implemented. In the end,the success test tells us that the thorough analysis of network device driver is the foundation of many applications,and it also provides a certain improvement to a lot of real applications,even to military application development.展开更多
