Abstract: When interfacing with a host, a networking device can handle a first data like Bulk Data Send. In response to a first doorbell ring, the networking device can read a first queue entry from a send queue in the host. Based on the first queue entry, the networking device can read the first data from a first memory in the host and then output the read first data. The networking device can also handle a second data like Direct Packet Push. The networking device can store a second data received from the host. In response to a second doorbell ring, the networking device can output the second data. The first data and the second data can be associated with first and second queue entries, both on the same send queue in the host. High-throughput and low-latency can be achieved. Small and large data packets can be accommodated.

Abstract: Network virtualization can be provided via network I/O interfaces, which may be partially or fully aware of the virtualization. Network virtualization can be reflected in the use of a first header and an additional header(s) for a data frame. A partially-aware transmit example can gather together data frame components, including its additional header(s), via a work queue entry. A fully-aware transmit example can refer to a transmit-side table to gather its additional header(s) and can track the state of its additional header(s) stored in a cache. A partially-aware receive example can handle an additional header(s), e.g., by writing it to host-memory. A fully-aware receive example can determine values from multiple headers (including its additional header(s)) to further determine where to write a data payload to host-memory. The examples can relieve a host's hypervisor from performing all the network virtualization processing. The fully-aware examples can incorporate JOY techniques.
