This application is by the service packetby the service packetby the service packet.
803: The service processing control device 1 decomposes a service to obtain a service feature string corresponding to the service.
For example, after the service is decomposed, the following information may be obtained: It is assumed that a service to be processed by the service packet includes a service feature A, a service feature B, a service feature C and a service feature D. First, the service feature A is processed, where different processing results may exist after the service feature A is processed, and it is assumed that three results, 1, 2 or 3, of processing the service feature A exist. If the result of processing the service feature A is 1, the service feature C continues to be processed, and finally the service feature B is processed; if the result of processing the service feature A is 2, the service feature D continues to be processed; and if the result of processing the service feature A is 3, the service processing ends.
804: The service processing control device 1 sends the service identity and the service feature string to each service processing device.
Referring to
805: Each service processing device encodes a service feature to obtain a service label used to represent the service feature.
A service feature encoding rule or a service feature encoding table may be preset on each service processing device. Herein, the service feature is encoded according to the preset service feature encoding rule or the service feature encoding table, to generate a service label corresponding to the service feature.
806: Each service processing device obtains, according to the service feature string, and service features that are supported by multiple service processing devices separately, a routing path for the service features; and generates a service routing table according to the service identity, the service label, and the routing path.
A method for generating a service routing table in this embodiment is the same as that in Embodiment 4, and details are not described again. Referring to the following Table 7, Table 7 is a service routing table of the service processing control device 2 in

807: The service processing control device 1 receives the service packet through the port 4.
808: The service processing control device 1 acquires, according to the flow label in the service packet, a service routing table corresponding to the service packet, and sets a service label A in the service packet according to the service routing table; and sends, according to the routing path, the service packet to the service processing device 3 configured to process a service feature A.
809: The service processing device 3 processes a service feature corresponding to the service label, and determines next-step processing according to a result of processing the service feature.
For example, if the result of processing the service feature A is 1, the service processing device 3 obtains by searching the table that a corresponding egress port is 2 and a next-hop service label is CB, and 810 and 811 continue to be performed; if the result of processing the service feature A is 2, the service processing device 3 obtains by searching the table that a corresponding egress port is 3 and a next-hop service label is D, and 812 and 813 continue to be performed; and if the result of processing the service feature A is 3, the service processing device 3 obtains by searching the table that a corresponding egress port is none and a next-hop service label is none, and the service processing device 3 no longer forwards the packet, for example, may discard the service packet directly.
810: The service processing device 3 modifies the service label in the packet to CB, that is, the service processing device 3 sets, in the service packet, a service label corresponding to a service feature that is to be processed in a next step, and then forwards the packet by using a port 2 of the service processing device 3, and sends the packet to the service processing device 2.
811: The service processing device 2 receives the service packet, and first processes the service feature C and then processes the service feature B according to the service label CB in the packet; and then obtains by searching Table 5 that a corresponding egress port is 3 and a next-hop service label is none, and therefore deletes the service label and sends the packet to the service processing device 1 through a port 3, and the procedure jumps to 813.
812: The service processing device 3 modifies the service label in the packet to D, that is, the service processing device 3 sets, in the service packet, a service label corresponding to a service feature that is to be processed in a next step, and then forwards the packet by using a port 3 of the service processing device 3, and sends the packet to the service processing device 1.
813: The service processing device 1 receives the service packet, and performs next-step processing on the service packet according to the service label in the packet, where the processing is sending the packet from the port 4 to the service processing control device 2.
In this embodiment, referring to Table 6, the service label in the service packet received by the service processing device 1 (that is, an incoming service label) may have two results, which may be label-free or the service label D. No matter which service label it is, the egress port corresponding to the next-step processing is 4, and the next-hop service label is none; therefore, the service processing device 1 sends the service packet from the port 4 of the service processing device 1 to the service processing control device 2, and when the service label is D, the service label is deleted before the service packet is sent.
814: According to the service routing table shown in Table 7, the service packet received by the service processing control device 2 from the service processing device 1 has no service label, that is, a corresponding incoming service label is none; the service processing control device 2 searches the service routing table to obtain that a corresponding egress port is 0 and a next-hop service label is none, which indicates that there is no remaining service feature to be processed, so that the service processing control device 2 sends the service packet out of the service processing system from a port 0, and the processing procedure of the service packet ends.
