摘要： Examples described herein relate to offload reliable transport management to a network interface device and store packets to be resent, based on received packet receipt acknowledgements (ACKs), into one or more kernel space queues that are also accessible in user space.

摘要： Technologies for managing a single-producer and single-consumer ring include a producer of a compute node that is configured to allocate data buffers, produce work, and indicate that work has been produced. The compute node is configured to insert reference information for each of the allocated data buffers into respective elements of the ring and store the produced work into the data buffers. The compute node includes a consumer configured to request the produced work from the ring. The compute node is further configured to dequeue the reference information from each of the elements of the ring that correspond to the portion of data buffers in which the produced work has been stored, and set each of the elements of the ring for which the reference information has been dequeued to an empty (i.e., NULL) value. Other embodiments are described herein.

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： 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.
