ABSTRACT:
A method according to one embodiment may include storing data in a send buffer. A transmission header may be created, in which the transmission header may include a pointer to the data in the send buffer. Packets may be transmitted, in which the packets include the transmission header and the data linked to the transmission header by the pointer, wherein the packets are transmitted without copying the data to create the packets. Of course, many alternatives, variations and modifications are possible without materially departing from this embodiment.
