Abstract: A method for link-level flow control includes establishing a plurality of logical links over a physical link between a transmitting entity and a receiving entity in a network. Respective maximum limits of transmission credits are assigned to the logical links, the credits corresponding to space available to the links in a dynamically allocable portion of a receive buffer at the receiving entity, such that a sum of the maximum limits for all of the logical links corresponds to an amount of space substantially larger than a total volume of the space in the dynamically allocable portion of the receive buffer. Responsive to traffic from the transmitting entity to the receiving entity on a given one of the logical links, one or more of the credits are allocated to the given logical link when it is determined that a total of the credits allocated to the given logical link is no greater than the respective maximum limit, and that a total of the credits allocated to all of the logical links together corresponds to an allocated volume that is no greater than the total volume of the space in the dynamically allocable portion of the receive buffer. Transmission of data over the given logical link is controlled responsive to the allocated credits.

Abstract: Apparatus for interfacing a computing device with a network includes a switch and an interface adapter. The interface adapter includes packet generation circuitry, for preparing a packet for transmission onto the network through the switch, and a buffer, coupled to receive and store the packet prepared by the packet generation circuitry. An output interface, coupled between the buffer and a first port of the switch, submits a notification to the first port that the packet has been prepared in the buffer. Upon receiving a response from the first port indicating that a second port of the switch, connected to the network, is ready to transmit the packet, the output interface conveys the packet to the first port, whereupon the first port passes the packet to the second port for transmission onto the network.

Abstract: A network interface device includes a fabric interface, adapted to exchange messages over a switch fabric with a plurality of host processors, the messages containing data, and a network interface, including one or more ports adapted to be coupled to a network external to the switch fabric. Message processing circuitry is coupled between the fabric interface and the network interface, so as to enable at least first and second host processors among the plurality of the host processors to use a single one of the ports substantially simultaneously so as to transmit and receive frames containing the data over the network.

Abstract: A network interface adapter includes a network interface and a client interface, for coupling to a client device so as to receive from the client device work requests to send messages over the network using a plurality of transport service instances. Message processing circuitry, coupled between the network interface and the client interface, includes an execution unit, which generates the messages in response to the work requests and passes the messages to the network interface to be sent over the network. A memory stores records of the messages that have been generated by the execution unit in respective lists according to the transport service instances with which the messages are associated. A completion unit receives the records from the memory and, responsive thereto, reports to the client device upon completion of the messages.

Abstract: A method for communication between a network interface adapter and a host processor coupled thereto includes writing information using the network interface adapter to a location in a memory accessible to the host processor. Responsive to having written the information, the network interface adapter places an event indication in an event queue accessible to the host processor. It then asserts an interrupt of the host processor that is associated with the event queue, so as to cause the host processor to read the event indication and, responsive thereto, to process the information written to the location.
