1. A data packet processing method, applied to a satellite communications system, wherein the method comprises:
receiving, by a first satellite, a data packet that carries an Internet Protocol (IP) address of a destination device, and the IP address comprises a network identifier (NID);
determining, by the first satellite based on the NID, mapping relationship information, and an ephemeris, an identifier of a destination satellite corresponding to the NID, wherein the mapping relationship information is used to record a mapping relationship between the NID, an earth surface identifier (EID), and a space identifier (SID); and
sending, by the first satellite, the data packet to the destination satellite.
