Abstract: Technologies for scalable packet reception and transmission include a network device. The network device is to establish a ring that is defined as a circular buffer and includes a plurality of slots to store entries representative of packets. The network device is also to generate and assign receive descriptors to the slots in the ring. Each receive descriptor includes a pointer to a corresponding memory buffer to store packet data. The network device is further to determine whether the NIC has received one or more packets and copy, with direct memory access (DMA) and in response to a determination that the NIC has received one or more packets, packet data of the received one or more packets from the NIC to the memory buffers associated with the receive descriptors assigned to the slots in the ring.

Abstract: Packets are differentiated based on their traffic class. A traffic class is allocated bandwidth for transmission. One or more core or thread can be allocated to process packets of a traffic class for transmission based on allocated bandwidth for that traffic class. If multiple traffic classes are allocated bandwidth, and a traffic class underutilizes allocated bandwidth or a traffic class is allocated insufficient bandwidth, then allocated bandwidth can be adjusted for a future transmission time slot. For example, a higher priority traffic class with excess bandwidth can share the excess bandwidth with a next highest priority traffic class for use to allocate packets for transmission for the same time slot.

Abstract: Packets received at an input port can be sub-divided into timeslots. A core or thread can process packets associated with a timeslot. The timeslot size can be increased or decreased based on utilization of a core that is allocated to process packets associated with a timeslot. A timeslot number can be assigned to each received packet. For transmission of the received packets, the timeslot number can be used to maintain an order of transmission to attempt to reduce out-of-order packet transmission.
