摘要： A network element one or more network ports, network time circuitry and packet processing circuitry. The network ports are configured to communicate with a communication network. The network time circuitry is configured to track a network time defined in the communication network. In some embodiments the packet processing circuitry is configured to receive a definition of one or more timeslots that are synchronized to the network time, and to send outbound packets to the communication network depending on the timeslots. In some embodiments the packet processing circuitry is configured to process inbound. packets, which are received from the communication network, depending on the timeslots.

摘要： A network adapter includes a host interface configured to communicate with a host, a network interface configured to communicate with a communication network, and packet processing circuitry. The packet processing circuitry is configured to receive a packet from the host via the host interface, or from the communication network via the network interface, to receive an indication of a network time used for synchronizing network elements in the communication network, to match the packet to a rule, the rule including a condition and an action, and to perform the action in response to the packet meeting the condition, wherein one or more of (i) the condition in the rule and (ii) the action in the rule, depend on the network time.

摘要： A network interface device includes a host interface for connection to a host processor having a memory. A network interface is configured to transmit and receive data packets over a data network, which supports multiple tenant networks overlaid on the data network. Processing circuitry is configured to receive, via the host interface, a work item submitted by a virtual machine running on the host processor, and to identify, responsively to the work item, a tenant network over which the virtual machine is authorized to communicate, wherein the work item specifies a message to be sent to a tenant destination address. The processing circuitry generates, in response to the work item, a data packet containing an encapsulation header that is associated with the tenant network, and to transmit the data packet over the data network to at least one data network address corresponding to the specified tenant destination address.

摘要： A communication apparatus includes a host interface, connected to a peripheral component bus so as to communicate with a CPU and a memory of a host computer. A network interface is connected to a network. Packet processing circuitry is configured to receive from a first interface a data packet including a set of one or more headers that include header fields having respective values, to identify, responsively to at least one of the header fields, a corresponding entry in a header modification table that specifies a header modification operation, to modify the set of headers in accordance with the header modification operation, to check whether the entry specifies an additional header modification operation, to output the modified set of headers if the entry does not specify an additional header modification operation, and, if the entry specifies an additional header modification operation, to feed-back the modified set of headers.

摘要： A computing system includes at least one peripheral bus, a peripheral device connected to the at least one peripheral bus, at least one memory, and first and second system components. The first system component is (i) associated with a first address space in the at least one memory and (ii) connected to the peripheral device via the at least one peripheral bus. The second system component is (i) associated with a second address space in the at least one memory and (ii) connected to the peripheral device via the at least one peripheral bus. The first system component is arranged to cause the peripheral device to access the second address space that is associated with the second system component.

摘要： A Network-Connected Device (NCD) includes a network interface, a host interface, an NCD memory and an NCD processor. The network interface is configured for communicating over a network. The host interface is configured for communicating with a host. The NCD memory is configured to buffer packet information that originates from the host and pertains to a packet to be transmitted to the network at a specified transmission time. The NCD processor is configured to process the buffered packet information before the specified transmission time, and to transmit the packet to the network at the specified time. Processing of the packet information and transmission of the packet are decoupled from buffering of the packet information.
