Abstract: Examples may include an apparatus having a packet receiver to receive a packet, the packet including a packet header having a deadline and a destination network node. The apparatus includes a routing table including a current latency for a path to the destination network node for the packet. The apparatus further includes a reprioritization component to get the deadline for delivery of the packet to the destination network node, to set a remaining time for the packet to the deadline minus a current time, to subtract the current latency from the remaining time when the packet is to be routed, and to assign the packet to one of a plurality of deadline bins based at least in part on the remaining time, each deadline bin associated with one of a plurality of transmit queues, the plurality of deadline bins arranged in a deadline priority order from a highest priority to a lowest priority. The apparatus also includes a packet transmitter to transmit packets from the plurality of transmit queues, the plurality of transmit queues being accessed in the deadline priority order.

Abstract: Technologies for end-to-end quality of service for I/O operations include a compute device in an I/O path. The compute device receives from another of the compute devices in the I/O path, an I/O request packet. The I/O request packet includes one or more QoS deadline metadata. The QoS deadline metadata is indicative of latency information relating to a currently executing workload relative to a specified QoS. The compute device evaluates the QoS deadline metadata and assigns a priority to the I/O request packet as a function of the evaluated metadata.

Abstract: Technologies include a network switch configured to perform packet replication. The network switch includes a network communicator, an entity manager, and a tag manager. The network communicator is to receive a data packet, and the entity manger is to identify an entity associated with the data packet and determine a tag associated with the entity. Additionally, the tag manager is to determine a packet replication configuration associated with the tag, and perform one or more per-port forwarding actions based on the packet replication configuration. The packet replication configuration includes one or more destination ports to be masked and a number of copies to be replicated to be sent out on of at least one destination port.
