Disclosed are a method, device, and system for packet processing. A state value used for identifying a topology state of a service node within a designated time is preconfigured for packets in a packet stream; when selecting a service node in a next hop for the packets, instead of using the topology state of a current actual service node in the next hop as the basis for selection, this facilitates the use of the topology state of the service node within the designated time as identified by the state value as the basis for selection; as long as the state values carried by each packet in a same packet stream are identical, even when the topology states of the service nodes are changed, a same service node can still be selected for the packets in a same packet stream, thus preventing the problem of packet redirection in a same packet stream. |
