Abstract: Techniques are disclosed for using a forwarding microchip to implement a network functions virtualization (NFV) backplane within a network device. In one example, processing circuitry of a forwarding microchip establishes a respective logical connection between each of a plurality of virtual ports of the forwarding microchip and each of a plurality of virtual ports configured for respective software-implemented virtual network functions (VNFs) executing on the network device. The processing circuitry receives packets via one or more physical ports of the forwarding microchip and forwards, using the logical connections between each of the plurality of virtual ports of the forwarding microchip and each of the plurality of virtual ports configured for the respective software-implemented VNFs, the packets to a Network Interface Controller (NIC) for forwarding to the plurality of virtual ports configured for the respective software-implemented VNFs.
