Abstract
This disclosure describes techniques for a network interface controller (NIC) to communicate over a network according to a specified transmission communication protocol. The NIC receives, from a host processor, an indication of a data unit and an indication of a header template. The NIC generates, independent of the specified transmission communication protocol, metadata for transmitting a segment of the data unit over a network. The NIC generates, at last partly using the metadata, header fields that comply with the specified transmission communication protocol. The NIC processes the header template and the header fields to generate a packet header, and the NIC transmits, over the network, a packet including the packet header and the segment of the data unit.
