摘要： Technologies for load balancing a storage network include a system. The system includes circuitry to adjust routing rules in a network interface controller to deliver a packet from one of multiple uplinks to one of any physical functions, circuitry to remap, in response to a failure of a switch, a port from one physical function to another physical function, and circuitry to communicate control data between a software defined network controller and one or more agents in one or more host endpoints with a hierarchical distributed hashing table.

摘要： The present disclosure describes a method and apparatus for network traffic processing in a non-uniform memory access architecture system. The method includes allocating a Tx/Rx Queue pair for a node, the Tx/Rx Queue pair allocated in a local memory of the node. The method further includes routing network traffic to the allocated Tx/Rx Queue pair. The method may include designating a core in the node for network traffic processing. Of course, many alternatives, variations and modifications are possible without departing from this embodiment.

摘要： Examples described herein relate to a reliable transport protocol for packet transmission using an Address Family of an eXpress Data Path (AF_XDP) queue framework, wherein the AF_XDP queue framework is to provide a queue for received packet receipt acknowledgements (ACKs). In some examples, an AF_XDP socket is to connect a service with a driver for the network device, one or more queues are associated with the AF_XDP socket, and at least one of the one or more queues comprises a waiting queue for received packet receipt ACKs. In some examples, at least one of the one or more queues is to identify one or more packets for which ACKs have been received. In some examples, the network device is to re-transmit a packet identified by a descriptor in the waiting queue based on non-receipt of an ACK associated with the packet from a receiver.

摘要： Technologies for enhanced network discovery and configuration include a network with a fabric manager and multiple network devices. A network device requests platform information from a management controller and receives the platform information via a sideband interface. The network device broadcasts a discovery message indicative of the platform information on a link layer network. The fabric manager discovers the network topology with an enhanced link layer discovery protocol and creates a vPOD in the network. The vPOD includes an application network with multiple racks. The fabric manager creates a tagged network domain for the vPOD. The fabric manager sends an out-of-band configuration command to the network device with a tag associated with the vPOD. After receiving the out-of-band configuration command, the network device receives a packet, compares domain metadata of the packet to the tag received from the fabric manager, and routes the packet. Other embodiments are described and claimed.

摘要： Methods and apparatus for smart switch centered next generation cloud infrastructure architectures. Smart server switches are implemented in place of Top of Rack (ToR) switches and other switches in cloud infrastructure that include programmable switch chips (e.g., P4 switch chips) that are programmed via data plane runtime code executing on the switch chips to implement data plane operations in hardware in the switches. Meanwhile, control plane operations are implemented in the server switches via software executing on one or more CPUs or are implemented via servers that are coupled to the server switches. The data plane runtime code is used to forward data traffic and storage traffic in hardware via the programmable switch chips in a manner that offloads forwarding to hardware in virtualized cloud environments.

摘要： Technologies for flexible I/O protocol acceleration include a computing device having a root complex, a smart endpoint coupled to the root complex, and an offload complex coupled to the smart endpoint. The smart endpoint receives an I/O transaction that originates from the root complex and parses the I/O transaction based on an I/O protocol and identifies an I/O command. The smart endpoint may parse the I/O transaction based on endpoint firmware that may be programmed by the computing device. The smart endpoint accelerates the I/O command and provides a smart context to the offload complex. The smart endpoint may copy the I/O command to memory of the smart endpoint or the offload complex. The smart endpoint may identify protocol data based on the I/O command and copy the protocol data to the memory of the smart endpoint or the offload complex. Other embodiments are described and claimed.

摘要： Examples include techniques for input/output (I/O) access to physical memory or storage by a virtual machine (VM) or a container. Example techniques include use of a queue pair maintained at a controller for I/O access to the physical memory or storage. The queue pair including a submission queue and a completion queue. An assignment of a process address space identifier (PASID) to the queue pair facilitates I/O access to the physical memory or storage for a given VM or container.

摘要： Generally, this disclosure relates to adaptive interrupt moderation. A method may include determining, by a host device, a number of connections between the host device and one or more link partners based, at least in part, on a connection identifier associated with each connection; determining, by the host device, a new interrupt rate based at least in part on a number of connections; updating, by the host device, an interrupt moderation timer with a value related to the new interrupt rate; and configuring the interrupt moderation timer to allow interrupts to occur at the new interrupt rate.
