摘要： A method includes receiving in a network switch of a communication network communication traffic that originates from a source node and arrives over a route through the communication network traversing one or more preceding network switches, for forwarding to a destination node. In response to detecting in the network switch a compromised ability to forward the communication traffic to the destination node, a notification is sent to the preceding network switches. The notification is to be consumed by the preceding network switches and requests the preceding network switches to modify the route so as not to traverse the network switch.

摘要： Network apparatus includes a plurality of interfaces, which are coupled to a network so as to receive and transmit data packets having respective link-layer headers and network-layer headers. Each link-layer header includes respective source and destination link-layer addresses and a link-layer priority value. Switching and routing logic is configured, responsively to the network-layer headers, to transfer each data packet from a respective ingress interface to a respective egress interface and to modify the source and destination link-layer addresses of the transferred data packet while copying the link-layer priority value from the ingress interface to the egress interface without modification.

摘要： A switching apparatus includes multiple ports, each including a respective buffer, and a switch controller. The switch controller is configured to concatenate the buffers of at least an input port and an output port selected from among the multiple ports for buffering traffic of a long-haul link, which is connected to the input port and whose delay exceeds buffering capacity of the buffer of the input port alone, and to carry out end-to-end flow control for the long haul link between the output port and the input port.

摘要： A network adapter includes a network interface, a host interface and processing circuitry. The network interface connects to a communication network for communicating with remote targets. The host interface connects to a host that accesses a Multi-Channel Send Queue (MCSQ) storing Work Requests (WRs) originating from client processes running on the host. The processing circuitry is configured to retrieve WRs from the MCSQ and distribute the WRs among multiple Send Queues (SQs) accessible by the processing circuitry.

摘要： In a fabric of network elements one network element has an object pool to be accessed stored in its memory. A request for atomic access to the object pool by another network element is carried out by transmitting the request through the fabric to the one network element, performing a remote direct memory access to a designated member of the object pool, atomically executing the request, and returning a result of the execution of the request through the fabric to the other network element.

摘要： A Network Interface (NI) includes a host interface, which is configured to receive from a host processor of a node one or more cross-channel work requests that are derived from an operation to be executed by the node. The NI includes a plurality of work queues for carrying out transport channels to one or more peer nodes over a network. The NI further includes control circuitry, which is configured to accept the cross-channel work requests via the host interface, and to execute the cross-channel work requests using the work queues by controlling an advance of at least a given work queue according to an advancing condition, which depends on a completion status of one or more other work queues, so as to carry out the operation.

摘要： An MPI collective operation carried out in a fabric of network elements by transmitting MPI messages from all the initiator processes in an initiator node to designated ones of the responder processes in respective responder nodes. Respective payloads of the MPI messages are combined in a network interface device of the initiator node to form an aggregated MPI message. The aggregated MPI message is transmitted through the fabric to network interface devices of responder nodes, disaggregating the aggregated MPI message into individual messages, and distributing the individual messages to the designated responder node processes.
