Abstract: In one embodiment, a network device, including a network interface to receive packets over a packet data network, and a hierarchical policer to provide queue fairness for a plurality of network flows competing for access to a multiplex network receive queue, and including level one meters to label the received packets, a level two meter to receive at least some of the labeled packets and relabel the at least some labeled packets, and queueing logic add the packets labeled with a first label-type to the multiplex network receive queue and drop the packets labeled with a third label-type.

Abstract: Apparatus for data communication includes a network interface for connection to a packet data network and a host interface for connection to a host computer, which includes a central processing unit (CPU) and a host memory. Packet processing circuitry receives, via the host interface, from a kernel running on the CPU, associations between multiple remote direct memory access (RDMA) sessions and multiple different User Datagram Protocol (UDP) 5-tuple, which are assigned respectively to the RDMA sessions, and receives from an application running on the CPU a request to send an RDMA message, using a selected group of one or more of the RDMA sessions, to a peer application over the packet data network, and in response to the request, transmits, via the network interface, one or more data packets using a UDP 5-tuple that is assigned to one of the RDMA sessions in the selected group.

Abstract: Systems and methods enable session sharing for session-based remote direct memory access (RDMA). Multiple queue pairs (QPs) can be added to a single session and/or session group where each of the QPs has a common remote. Systems and methods may query a session ID for an existing session group and then use the session ID with an add QP request to join additional QPs to an existing session. Newly added QPs may share one or more features with existing QPs of the session group, such as encryption parameters. Additionally, newly added QPs may be configured with different performance or quality of service requirements, thereby isolating performance, and permitting true scaling for high performance computing applications.

Abstract: Methods and systems provided herein involve extracting an input/output (I/O) operation from a packet received over an I/O pipeline, the I/O operation comprising either a read request to read data from at least one storage device or a write request to write data to the at least one storage device; determining that an address associated with the I/O operation exists in a lookup table that is provided for thin provisioning of the at least one storage device; performing one or more RAID calculations associated with the at least one storage device based on the address and the I/O operation; and accessing the at least one storage device to perform the I/O operation based on the one or more RAID calculations; and second processing component configured to carry out a second set of operations that occur when the address associated with the I/O operation does not exist in the lookup table.

Abstract: A cross-network bridging apparatus includes a bus interface and bridging circuitry. The bus interface is configured for connecting to a system bus. The bridging circuitry is configured to translate between (i) system-bus transactions that are exchanged between one or more local devices that are coupled to the system bus and served by the system bus and one or more remote processors located across a network from the apparatus, and (ii) data units that convey the system-bus transactions, for transmitting and receiving as network packets over the network to and from the remote processors.
