Abstract: A device includes ports, a packet processor, and a memory management circuit. The ports communicate packets over a network. The packet processor processes the packets using queues. The memory management circuit maintains a shared buffer in a memory and adaptively allocates memory resources from the shared buffer to the queues, maintains in the memory, in addition to the shared buffer, a shared-reserve memory pool for use by the queues, identifies, among the queues, a queue that requires additional memory resources, the queue having an occupancy that is (i) above a current value of a dynamic threshold, rendering the queue ineligible for additional allocation from the shared buffer, and (ii) no more than a defined margin above the current value of the dynamic threshold, rendering the queue eligible for allocation from the shared-reserve memory pool, and allocates memory resources to the identified queue from the shared-reserve memory pool.

Abstract: Apparatuses, systems, and techniques to establish a redundant communication pathway to a management network. In at least one embodiment, the redundant communication pathway is established by creating a virtual interface using a network device, and using the virtual interface to communicate with the management network via a management port of a second network device, and a connection between a first data port of the network device and a second data port of the second network device.

Abstract: Technologies for spreading packets of transport flows across multiple network paths are described. A network controller includes a transport layer and a network layer. The transport layer includes a flow scheduler to schedule a transport flow from one of a plurality of transport flows. The network layer includes multipath logic to receive packets from the transport flow and select which path of a plurality of paths to a destination to use for the packets based on path congestion weights corresponding to the plurality of paths.

Abstract: A networking device and system are described, among other things. An illustrative system is disclosed to include a first processor to perform compute tasks associated with an operation; and a second processor to perform control plane tasks associated with the operation. The control plane tasks performed by the second processor relieve the first processor from responsibilities of performing the control plane tasks associated with the operation.

Abstract: A method and system are provided for limiting unnecessary data traffic on the data busses connecting the various levels of system memory. Some embodiments may include processing an invalidation command associated with a system or network operation requiring temporary storage of data in a local memory area. The invalidation command may comprise a memory location indicator capable of identifying the physical addresses of the associated data in the local memory area. Some embodiments may preclude the data associated with the system or network operation from being written to a main memory by invalidating the memory locations holding the temporary data once the system or network operation has finished utilizing the local memory area.

Abstract: An apparatus comprises a support structure and one or more first optical components on the support structure that communicatively couple with a first endpoint. The one or more first optical components are configured to output and receive optical signals that travel over a free space medium to establish a secure link between the first endpoint and a second endpoint.

Abstract: A method for communication includes mapping transport sequence numbers in headers of data packets received from a network to respective buffers in a memory of a host computer. At least a part of the data from payloads of the received data packets is written directly to the respective buffers.

Abstract: Disclosed are apparatuses, systems, and techniques that improve efficiency and decrease latency of remote direct memory access (RDMA) operations. The techniques include but are not limited to unified RDMA operations that are recognizable by various communicating devices, such as network controllers and target memory devices, as requests to establish, set, and/or update arrival indicators in the target memory devices responsive to arrival of one or more portions of the data being communicated.
