Abstract: A packet forwarding method and apparatus are described that pertain to the field of communication technologies. During selecting, from outbound interfaces of a plurality of forwarding chips, an outbound interface used for packet forwarding, a chassis-shaped device considers both: a role of the outbound interface (whether the outbound interface is an outbound interface of a shortest path or an outbound interface of a non-shortest path), and a congested state of the outbound interface. As such, the chassis-shaped device flexibly selects a forwarding path for a data packet based on a congestion situation of the forwarding path. In this way, an application of an adaptive routing technology is extended to the chassis-shaped device.

Abstract: A packet forwarding method and system. A first network device encapsulates a to-be-forwarded packet as a first packet, and sends the first packet to a second network device, where the first packet carries a destination Media Access Control (MAC) address encapsulation instruction, the destination MAC address encapsulation instruction is used to instruct the second network device to encapsulate a destination MAC address for the first packet, the to-be-forwarded packet carries a destination internet protocol (IP) address, and the destination MAC address is a MAC address of a destination host corresponding to the destination IP address; the second network device generates a second packet containing the destination MAC address according to the destination MAC address encapsulation instruction carried by the received first packet, and forwards the second packet to the destination host corresponding to the destination MAC address.
