Abstract
The packet forwarding device and method of the invention assign a virtual port number to each peripheral interface. The device and method can recognize and process the packets coming from or transferred to the virtual port according to the packet direct forward function of the forward device. Thus, the device and method can process the packets that are inputted to or outputted from the peripheral interface and the network device connected to the peripheral interface in a manner similar to the typical method for processing the packets that are only inputted to or outputted from the physical port.
