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: In accordance with an embodiment, a method includes generating, by a network device, a flow table comprising a plurality of flow records; determining, by the network device, whether a data flow corresponding to the plurality of flow records is an abnormal flow; and sending, by the network device, a flow record of the abnormal flow to an analyzer in response to a determination that the data flow is the abnormal flow, so that the analyzer analyzes the abnormal flow.
