Abstract
Methods and systems for a more efficient transmission of network traffic are provided. According to one embodiment, payload data originated by a user process running on a host processor of a network device is fetched by an interface of the network device by performing direct virtual memory addressing of a user memory space of a system memory of the network device on behalf of a network interface unit of the network device. The direct virtual memory addressing maps physical addresses of various portions of the payload data to corresponding virtual addresses. The payload data is segmented by the network interface unit across one or more packets.
