Abstract
Technologies for offloading virtual service endpoint capabilities include a compute node and network controller. A device driver of a compute device may discover offloaded virtual service endpoint capability of a network interface card of the compute device. The device driver may advertise the offloaded virtual service endpoint capability to a network agent and virtual network functions provided by the compute device. An out-of-band tag may be associated with the offloaded virtual service endpoint to identify network packets to be processed by the offloaded virtual service endpoint. The network agent may add a flow entry to a forwarding table of a network switch of the compute device based on network flow information received from the network controller. The network agent may also associate the added flow entry with the offloaded virtual service endpoint based on the out-of-band tag and configure the offloaded virtual service endpoint based on the network flow information.
