    摘要： Embodiments of the present invention provide a packet sending method, a router, and a service switching entity. According to the packet sending method provided in the embodiments of the present invention, 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.

    摘要： This application provides an address processing method and a network device. The method includes: obtaining, by a first network device, an address; determining, by the first network device, a length of a valid address of the address, where the valid address of the address is a 1 st bit, whose bit value is 1, of the address to a last bit of the address; and adding, by the first network device when the length of the valid address of the address is less than a table width of a target table, S zeros before the valid address of the address to obtain an adjusted address, and processing the adjusted address based on the adjusted address and the target table, where S is a difference between the table width of the target table and the length of the valid address of the address. Based on the foregoing technical solution, the length of the address obtained and processed by the first network device may not be equal to the table width of the target table.

    摘要： Embodiments of the present invention disclose a flow entry delivering method, a flow entry storage method, a related apparatus, and a related system. A controller obtains a device identifier of a network device and at least one flow entry that is used to perform a function on the network device. The controller obtains storage information of the network device according to the device identifier, and the storage information includes free space in storage space of the network device that is used to store a flow entry. The controller compares the free space with a total capacity of the at least one flow entry. The controller determines, according to a comparison result, whether the network device has sufficient free storage space to store the at least one flow entry. When the network device has the storage space greater than or equal to the capacity of the flow entry, the controller delivers the at least one flow entry, or when the network device has no storage space to store the flow entry, the controller does not deliver the at least one flow entry, thereby improving a success rate of delivering a flow entry by the controller.
