Abstract: A method for forwarding message, comprising: receiving, by a forwarding plane device, a first message, and looking up a first entry matched with the first message in a flow table of the forwarding plane device, wherein the forwarding plane device is a device compliant with a network architecture in which control and forwarding are separated; performing, by the forwarding plane device, a first operation on the first message for limiting its message forwarding rate according to the first entry. Further, a corresponding device is also provided in an embodiment of this disclosure. With the technical solutions provided in embodiments of this disclosure, the forwarding plane device can put limits on its message forwarding rate.

Abstract: The application provide a packet sending method, a router, and a service switching entity. According to the application, a router determines a flow group identifier of a service packet and information about a next-hop service switching entity according to a user identifier and IP 5-tuple information; and forwards the packet to the next-hop service switching entity according to the information about the next-hop service switching entity, so that the next-hop service switching entity determines a corresponding destination service instance according to the user identifier, the flow group identifier, a router identifier, and a processing result, and forwards the packet to the destination service instance, to perform corresponding service processing, thereby implementing service packet forwarding among service instances. The router in the method provided in the embodiments has a flow steering function, and steers a flow to a specified path to perform node-by-node processing.

Abstract: Embodiments disclose a packet forwarding method and device. The method includes: obtaining, by a packet forwarding device, a feature character included in a packet to be forwarded. The feature character is obtained by parsing, according to a preset packet content parsing policy, other content included in the packet to be forwarded except a 5-tuple. The method includes determining, according to a correspondence between different feature characters and corresponding routing information, routing information corresponding to the obtained feature character, and sending, according to the determined routing information, the packet to be forwarded
