Examples described herein relate to a network interface device that includes circuitry, configured to perform encryption of data, generate one or more packets from the encrypted data, cause transmission of the one or more packets with the encrypted data, manage reliability of transport of the transmitted one or more packets with the encrypted data, and share protocol state information between a host system and the network interface device using connectivity based on user space accessible queues.

Transport and cryptography offload to a network interface device

A stacked memory such as a high bandwidth memory (HBM) with a wide data path is used by a streaming pipeline in a network interface controller to buffer segments of a data packet to allow the network interface controller to perform operations on the packet payload. The headers and packet payload can be scanned and classified concurrently with the buffered payload parsed in parallel.

Method and apparatus to perform operations on multiple segments of a data packet in a network interface controller

Technologies for controlling jitter at network packet egress at a source computing device include determining a switch time delta as a difference between a present switch time and a previously captured switch time upon receipt of a network packet scheduled for transmission to a target computing device and determining a host scheduler time delta as a difference between a host scheduler timestamp associated with the received network packet and a previously captured host scheduler timestamp. The source computing device is additionally configured to determine an amount of previously captured tokens present in a token bucket, determine whether there are a sufficient number of tokens available in the token bucket to transmit the received packet as a function of the switch time delta, the host scheduler time delta, and the amount of previously captured tokens present in the token bucket, and schedule the received network packet for transmission upon a determination that sufficient tokens in the token bucket.

Technologies for managing exact match hash table growth include a network computing device which includes a compute engine and a network interface controller (NIC). The NIC is configured to allocate a plurality of physical bucket addresses in non-contiguous chunks of memory of the compute engine, configure a bucket threshold value as a function of a hash size of the hash table, generate a plurality of virtual bucket addresses as a function of the bucket threshold value, and map each generated virtual bucket address to an allocated physical bucket address. Other embodiments are described herein.

Technologies for managing network statistic counters include a network interface controller (NIC) of a computing device configured to identify a statistic counter of and a software consumer associated with a received network packet and identify an active counter page as a function of the identified software consumer. The NIC is further configured to read a value of the statistic counter stored at a counter memory address of a corresponding counter identifier entry of the identified active counter page, increment a read value of the statistic counter, and write the incremented value of the statistic counter back to the counter memory address. Additionally, in response to detecting a notification triggering event, generating a notification message that includes a present value of the statistic counter and a present value of each of the other statistic counters of the active counter page, and transmit the generated notification message to the software consumer. Other embodiments are described herein.

Technologies for processing network packets by a network interface controller (NIC) of a computing device include a network interface, a packet processor, and a controller device of the NIC, each communicatively coupled to a memory fabric of the NIC. The packet processor is configured to receive an event message from the memory fabric and transmit a message to the controller device, wherein the message indicates the network packet has been received and includes the memory fabric location pointer. The controller device is configured to fetch at least a portion of the received network packet from the memory fabric, write an inbound descriptor usable by one or more on-die cores of the NIC to perform an operation on the fetched portion, and restructure the network packet as a function of an outbound descriptor written by the on-die cores subsequent to performing the operation. Other embodiments are described herein.
