Abstract: Data is received at a buffer used by a protocol processing stack which protocol processes the received data. The received data is made available to, for example, an application, before the protocol processing of the data is complete. If the protocol processing is successful, the data made available to the application is committed.

Abstract: Roughly described, method for managing data transmission between a host subsystem and a network interface device, in which the host writes data buffer descriptors into a DMA descriptor queue, and the network interface device writes completion events to notify the host when it has completed processing of data buffers. Each of the completion event descriptors notify the host of completion of data transfer between the NIC and one or more of the data buffers, and can also embed a queue empty notification inside the completion event.

Abstract: Method of managing interaction between a host subsystem and a peripheral device. Roughly described, the peripheral device writes an event into an individual event queue, and in conjunction therewith, also writes a wakeup event into an intermediary event queue. The wakeup event identifies the individual event queue. The host subsystem, in response to retrieval of the wakeup event from the intermediary event queue, activates an individual event handler to consume events from the individual event queue.

Abstract: Roughly described, a network interface device receiving data packets from a computing device for transmission onto a network, the data packets having a certain characteristic, transmits the packet only if the sending queue has authority to send packets having that characteristic. The data packet characteristics can include transport protocol number, source and destination port numbers, source and destination IP addresses, for example. Authorizations can be programmed into the NIC by a kernel routine upon establishment of the transmit queue, based on the privilege level of the process for which the queue is being established. In this way, a user process can use an untrusted user-level protocol stack to initiate data transmission onto the network, while the NIC protects the remainder of the system or network from certain kinds of compromise.

Abstract: Method for managing a queue in host memory for use with a peripheral device. Roughly described, the host makes a determination of the availability of space in the queue for writing new entries, in dependence upon historical knowledge of the number of queue entries that the host has authorized the device to write, and the number of entries that the host has consumed. In dependence on that determination, the host authorizes the device to write a limited number of new entries into the queue. The device writes entries into the queue dependence upon the number authorized. The host maintains a read pointer into the queue but does not need to maintain a write pointer, and the peripheral device maintains a write pointer into the queue but does not need to maintain a read pointer.
