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.

Abstract: Embodiments of the present invention disclose a method, an apparatus and a system for accessing a virtual private network by a virtual private cloud. A data center breakout gateway receives first configuration information; creates a first VPN instance according to identifier information of the VPN; determines VPC according to parameter information of the VPC, and binds the VPC to the first VPN instance; and sends second configuration information to the network side PE according to address information of the network side PE, where the second configuration information includes the identifier information of the VPN, so that the network side PE configures an upper layer VPN instance for the first VPN instance on the network side PE according to the identifier information of the VPN. In the embodiments of the present invention, the problem of automatically accessing the virtual private network by the virtual private cloud is solved.
