The traffic classifier sends a second packet to the first service routing trigger. Where the policy information includes: a filtering rule, an address of a service routing trigger, and a service identifier corresponding to the filtering rule. Where the filtering rule is used to identify a packet, and the service identifier is used to represent a sequence of a service node that processes the packet. Where the second packet is formed by adding the first service identifier to the first packet.

Abstract: An information management method includes that a controller generates a first message carrying an address of a first next hop of a network device. The first message includes first identification information. The first identification information instructs the network device to delete, from a next hop table stored in the network device, an entry of the first next hop corresponding to the address of the first next hop. The network device receives the first message, and deletes the entry of the first next hop as indicated by the first identification information. The controller withdraw an unavailable next hop by separately sending information about the next hop to the network device without route prefix information, effectively saving a system resource occupied for route withdrawal message exchanging between the controller and the network device, and improving service processing efficiency.
