    Abstract: A method for communication includes configuring a multi-level fat-tree network to include at least three levels of switches, including multiple modules arranged externally in a tree topology. Each module contains a respective group of the switches arranged in an internal tree extending over at least two of the levels of the network. A subset of the modules is selected to be active in carrying the communication traffic. The network is operated so as to convey communication traffic among the switches via the active modules, while the modules that are not in the selected subset remain inactive.

    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: A network device, a network interface controller, and a switch are provided. In one example, a shared buffer includes a plurality of portions, one or more ports read data from the shared buffer and write data to the shared buffer, and a controller circuit correlates egress ports with available portions among the plurality of portions as close as possible to a respective egress port.

    Abstract: A network device includes a plurality of ports, processing circuitry, and control circuitry. The ports are to receive communication traffic from a plurality of processing devices. The processing circuitry is to process the communication traffic received via the ports. The control circuitry is to assess one or more electrical-current consumption values associated with at least the network device, and, depending on the electrical-current consumption values, to control a traffic slew-rate of the communication traffic of at least a port among the ports to remain within a specified slew-rate range, the traffic slew-rate being defined as a rate at which a bandwidth of the communication traffic received via the port changes as a function of time.

    Abstract: A network device includes one or more ports, and action-select circuitry. The ports are to exchange packets over a network. The action-select circuitry is to determine, for a given packet, a first search key based on a first header field of the given packet, and a second search key based on a second header field of the given packet, to compare the first search key to a first group of compare values, to output a multi-element vector responsively to a match between the first search key and a first compare value, to generate a composite search key by concatenating the second search key and the multi-element vector, to compare the composite search key to a second group of compare values, and, responsively to a match between the composite search key and a second compare value, to output an action indicator for applying to the given packet.

    Abstract: Systems and methods are directed toward proactive and/or reactive notification and connection parameter adjustments responsive to live migration events. When an application or program is migrated to new underlying hardware, messages may be provided to associated senders to dynamically and/or temporarily adjust different connection parameters to reduce a likelihood of determining the connection is inactive. A proactive notification may broadcast status information during the live migration to each node in a network and/or to particular nodes associated with the migrating receiver. A reactive notification may provide a message regarding receiver status responsive to receiving incoming traffic.
