More Information
Summary:A network adapter includes a host interface, a network interface, a memory and packet processing circuitry. The memory holds a shared buffer and multiple queues allocated to the multiple host processors. The packet processing circuitry is configured to receive from the network interface data packets destined to the host processors, to store payloads of at least some of the data packets in the shared buffer, to distribute headers of at least some of the data packets to the queues, to serve the data packets to the host processors by applying scheduling among the queues, to detect congestion in the data packets destined to a given host processor among the host processors, and, in response to the detected congestion, to mitigate the congestion in the data packets destined to the given host processor, while retaining uninterrupted processing of the data packets destined to the other host processors.
