Method and system for enabling zero-copy transmission of streaming media data

A system for implementing zero copy transmission of streaming media data, said system comprising a streaming media server, and said streaming media server being configured to implement zero copy transmission of streaming media data based on a Linux network protocol stack, wherein

• said streaming media server configures a kernel space between a hardware device thereof and a user process, and configures the network protocol stack above a network card driver program in the kernel space;
• said kernel space allocates for real-time transport protocol packets formed by packaging to-be-transmitted streaming media data the following buffers:
• a temporarily allocated kernel buffer to include a head of said real-time transport protocol packets, and
• a temporarily mapped user buffer to include load of said real-time transport protocol packets;
• said network protocol stacks provides socket programming interfaces for the user process, and said socket programming interfaces comprise:
• “socket” used to create a socket, “close” used to close a socket, and “sendmsg” used to implement zero copy transmission of streaming media data;
• said network protocol stacks is used to transmit the real-time transport protocol packets in a form of streaming media packets whose head and load are separated.
