Abstract

Technology related to broadcast packet direct memory access (DMA) operations is disclosed. When a network interface controller (NIC) connected to a host computer receives a broadcast packet, it can transmit a request to an agent process running on the host computer for a plurality of destination buffers. In some embodiments, the request to the agent comprises all or part of the packet, or metadata about the packet. In such embodiments, the agent can use the contents of the request to identify services that should receive the packet. Alternatively, the NIC can identify the destination services and can transmit identifiers for the destination services to the agent. The agent can transmit requests for memory buffers to the services and can receive memory location identifiers in response. The agent can transmit the identifiers to the NIC, which can perform multiple DMA operations to write the broadcast packet to the identified memory locations.
