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.

Migration from a legacy network appliance to a network function virtualization (NFV) appliance

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.

Techniques for network packet classification, transmission and receipt

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.

Virtual switch scaling for networking applications

Technologies for buffering received network packet data include a compute device with a network interface controller (NIC) configured to determine a packet size of a network packet received by the NIC and identify a preferred buffer size between a small buffer and a large buffer. The NIC is further configured to select, from the descriptor, a buffer pointer based on the preferred buffer size, wherein the buffer pointer comprises one of a small buffer pointer corresponding to a first physical address in memory allocated to the small buffer or a large buffer pointer corresponding to a second physical address in memory allocated to the large buffer. Additionally, the NIC is configured to store at least a portion of the network packet in the memory based on the selected buffer pointer. Other embodiments are described herein.
