Netlink that implemented the interprocess communication function is a new protocol family in the Linux system. After referring to the Netlink mechanism of linux OS and implementation of 1553B protocol, and researching on the feasibility of combining sockets based on Netlink mechanism and 1553B protocol, this study designed the1553B protocol common socket based on Netlink mechanism. The socket API extends and defines the socket protocol stacks by Netlink common mechanism. It implements transmission of the1553B data using the socket API in Netlink mechanism. And it proves the convenience of the API through the experiment.
