Abstract: A processor-to-processor agent to provide connectivity over a processor-to-processor interconnect between services/network functions on different processors on a same compute node in a server is provided. The processor-to-processor agent can intercept socket interface calls using a network traffic filter in the network stack and redirect the packets based on traffic matching rules.

Abstract: A computing device includes an appliance status table to store at least one of reliability and performance data for one or more network functions virtualization (NFV) appliances and one or more legacy network appliances. The computing device includes a load controller to configure an Internet Protocol (IP) filter rule to select a packet for which processing of the packet is to be migrated from a selected one of the one or more legacy network appliances to a selected one of the one or more NFV appliances, and to update the appliance status table with received at least one of reliability and performance data for the one or more legacy network appliances and the one or more NFV appliances. The computing device includes a packet distributor to receive the packet, to select one of the one or more NFV appliances based at least in part on the appliance status table, and to send the packet to the selected NFV appliance. Other embodiments are described herein.

Abstract: A virtual machine (VM) can provision a region of memory for a queue to receive packet header, packet payload, and/or descriptors from the network interface. A virtual switch can provide a routing rule to a network interface to route a received packet header, packet payload, and/or descriptors associated with the VM to the provisioned queue. A direct memory access (DMA) transfer operation can be used to copy the received packet header, packet payload, and/or descriptors associated with the VM from the network interface to the provisioned queue without copying the packet header or payload to an intermediate buffer and from the intermediate buffer to the provisioned queue. A DMA operation can be used to transfer a packet or its descriptor from the provisioned queue to the network interface for transmission.

Abstract: Examples include a method of switching a packet by a virtual switch by receiving a system call to transmit a packet from a first application running in a first container on a first core, determining a destination for the packet, obtaining a buffer in an application memory space of the destination, copying the packet to the destination application memory space, and writing an entry for the packet to a queue assigned to the destination, the destination queue being in a queue manager. The packet may then be obtained by an entity at the destination.
