Abstract: Examples described herein relate to an apparatus comprising: a descriptor format translator accessible to a driver. In some examples, the driver and descriptor format translator share access to transmit and receive descriptors. In some examples, based on a format of a descriptor associated with a device differing from a second format of descriptor associated with the driver, the descriptor format translator is to: perform a translation of the descriptor from the format to the second format and store the translated descriptor in the second format for access by the device. In some examples, the device is to access the translated descriptor; the device is to modify content of the translated descriptor to identify at least one work request; and the descriptor format translator is to translate the modified translated descriptor into the format and store the translated modified translated descriptor for access by the driver.

Abstract: Examples include a computing system having a plurality of processing cores and a memory coupled to the plurality of processing cores. The memory has instructions stored thereon that, in response to execution by a selected one of the plurality of processing cores, cause the following actions. The selected processing core to receive a packet and get an original tuple from the packet. When no state information for a packet flow of the packet exists in a state table, select a new network address as a new source address for the packet, get a reverse tuple for a reverse direction, select a port for the packet from an entry in a mapping table based on a hash procedure using the reverse tuple, and save the new network address and selected port. Translate the packet's network address and port and transmit the packet.

Abstract: Technologies for distributing network packet workload are disclosed. A compute device may receive a network packet and determine network packet extrinsic entropy information that is based on information that is not part of the contents of the network packet, such as an arrival time of the network packet. The compute device may use the extrinsic entropy information to assign the network packet to one of several packet processing queues. Since the assignment of network packets to the packet processing queues depend at least in part on extrinsic entropy information, similar or even identical packets will not necessarily be assigned to the same packet processing queue.

Abstract: Telemetry information provided by a computing device includes switching key performance indicators (KPIs), platform KPIs, and topology information. The telemetry information is used to identify performance issues at the computing device, such as packets being dropped in a virtual switching stack or misconfiguration errors. A virtual switching monitor can identify which layers in the switching stack have errors and whether the errors occur along a transmit or receive path in the switching stack. A virtual switching controller can identify remedial actions that can be taken at the computing device to remedy a performance issue. A remedial action can be taken automatically, subject to user approval, or automatically after additional criteria are met.

Abstract: Examples may include techniques to route packets to virtual network functions. A network function virtualization load balancer is provided which routes packets to both maximize a specified distribution and minimize switching of contexts between virtual network functions. Virtual network functions are arranged to be able to shift a context from one virtual network function to another. As such, the system can be managed, for example, scaled up or down, regardless of the statefullness of the virtual network functions and their local contexts or flows.

Abstract: Aspects of data re-direction are described, which can include software-defined networking (SDN) data re-direction operations. Some aspects include data re-direction operations performed by one or more virtualized network functions. In some aspects, a network router decodes an indication of a handover of a user equipment (UE) from a first end point (EP) to a second EP, based on the indication, the router can update a relocation table including the UE identifier, an identifier of the first EP, and an identifier of the second EP. The router can receive a data packet for the UE, configured for transmission to the first EP, and modify the data packet, based on the relocation table, for rerouting to the second EP. In some aspects, the router can decode handover prediction information, including an indication of a predicted future geographic location of the UE, and update the relocation table based on the handover prediction information.
