Abstract
A virtual network comprising virtual machines executing at a computing environment is implemented. A software defined networking (SDN) appliance is configured to provide a connection to computing resources via a virtual network of a virtual computing environment. The SDN appliance includes a network interface card that are operable to interact with multiple field-programmable gate array (FPGA) devices are configured to be a hardware acceleration device for processing data traffic, and the FPGA device is configured to ingress a packet to a dataflow on one port and egress the packet from a different port associated with a different dataflow.
