Abstract:
A network device may include a first forwarding board, a second forwarding board and an interface board. The interface board may include a control apparatus and a network interface chip. The control apparatus may form a first upstream packet flow which is sent to the first forwarding board via a first I/O bus and a second upstream packet flow which is sent to the second forwarding board via a second I/O bus using data packets received through the network interface chip from the exterior of the network device. The control apparatus may selectively connect one of a first downstream packet flow and a second downstream packet flow to the network interface chip through the network interface bus according to an active/standby state of the first forwarding board and the second forwarding board, wherein the first downstream packet flow is processed by the first forwarding board and received through the first I/O bus and the second downstream packet flow is processed by the second forwarding board and received through the second I/O bus.

Claim (Index 8):
The packet forwarding method of  claim 7 , wherein the first I/O bus is a first PCI-E bus, the second I/O bus is a second PCI-E bus; the first forwarding board comprises a first PCI-E root complex (RC) connected to the first PCI-E bus, and a first CPU capable of driving the first PCI-E RC; the second forwarding board comprises a second PCI-E RC connected to the second PCI-E bus, and a second CPU capable of driving the second PCI-E RC; the interface board comprises a first PCI-E endpoint connected to the first PCI-E bus, a second PCI-E endpoint connected to the second PCI-E bus, a first receiving cache queue and a first sending cache queue which are connected to the first PCI-E endpoint, a second receiving cache queue and a second sending cache queue which are connected to the second PCI-E endpoint, and a network interface bus controller connected to the network interface chip via a network interface bus;\n the method comprises: duplicating a data packet received by the network interface bus controller from the network interface chip, and feeding copies of the data packet respectively into the first receiving cache queue and the second receiving cache queue to form the first upstream packet flow using the first receiving cache queue and form the second upstream packet flow using the second receiving cache queue; and the method further comprises: selectively connecting one of the first sending cache queue and the second sending cache queue to the network interface bus so that the selected one of the first sending cache queue and the second sending cache queue is connected to the network interface chip through the network interface bus.
