Abstract: The present invention discloses a packet processing method and system, and a device. A status value used to identify a topology status of service nodes at a specified time is preconfigured for a packet in a packet flow, so that when a service node in a next hop is selected for the packet, selection is performed not based on a topology status of current actual service nodes in the next hop, but based on the topology status, which is identified by the status value, of the service nodes at the specified time. As long as status values carried in packets in a same packet flow are the same, even if a topology status of service nodes changes, a same service node can still be selected for the packets in the same packet flow, thereby avoiding a problem of diversion of the packets in the same packet flow.

Abstract: This application discloses a multicast forwarding method and a multicast router. The method includes: listening to, by a first multicast router, a plurality of unicast packets passing through the first multicast router, and determining a set of unicast packets that are from a same upstream multicast router and that belong to a same unicast stream; when determining that destination addresses of at least two unicast packets in the unicast packet set are different, sending, by the first multicast router, a prune message to the upstream multicast router; and sending, by the first multicast router, the received unicast packets with the multicast identifier to the destination devices corresponding to the destination address group. The method is used to provide a new multicast method, so as to implement multicast functions of some routers in an existing unicast network architecture.
