Data Packet Sending Method, Mobile Router, and Network Device

摘要

The present invention relates to the field of communications technologies, and in particular, to a data packet sending method, a mobile router, and a network device for solving a technical problem in the prior art that data cannot be sent to a designated network node. In an embodiment, routing control policy information is set, and when a data packet is obtained, how to send the data packet may be determined according to the routing control policy information.

主权项

1. A method comprising:
obtaining, from a mobile node (MN), a first data packet from a first home address; determining, according to routing control policy information, whether to enable routing control for the first data packet, wherein the routing control policy information comprises indication information about whether routing control is enabled, and, in response to the indication information indicating that routing control is enabled, the routing control policy information further comprises home address status information; sending the first data packet to a designated routing node through a tunnel with the designated routing node according to the home address status information in the routing control policy information, in response to determining to enable routing control for the first data packet; obtaining a first processed data packet returned by the designated routing node; and sending the first processed data packet to a current mobile router of a destination node, wherein the current mobile router of the destination node sends the first processed data packet to the destination node, and wherein the first processed data packet is obtained by the designated routing node by processing the first data packet.
