Data Forwarding Method and Apparatus
First Claim
Patent Images
1. A data forwarding method, comprising:
- receiving, by a first node, a first data packet, wherein the first data packet comprises first data and an identifier of a second node of the first data, and wherein the identifier of the second node comprises an identifier of a root node serving user equipment or an identifier of a node that is of the root node and that serves the user equipment;
querying, by the first node, a first route mapping relationship based on the identifier of the second node to determine a third node, wherein the first route mapping relationship comprises a correspondence between the second node and the third node, and wherein the third node is a next-hop node that is indicated in the first route mapping relationship and that the first data packet reaches after passing through the first node; and
forwarding, by the first node, the first data to the third node.

Abstract
The present disclosure relates to data forwarding methods. One example method includes receiving, by a first node, a first data packet, where the first data packet includes first data and an identifier of a second node of the first data, querying, by the first node, a first route mapping relationship based on the identifier of the second node to determine a third node, where the first route mapping relationship includes a correspondence between the second node and the third node, and forwarding, by the first node, the first data to the third node.

9. An apparatus, comprising:
-
at least one processor; and a non-transitory computer-readable storage medium coupled to the at least one processor and storing programming instructions for execution by the at least one processor, wherein the programming instructions instruct the apparatus to; receive a first data packet, wherein the first data packet comprises first data and an identifier of a second node of the first data, and wherein the identifier of the second node comprises an identifier of a root node serving user equipment or an identifier of a node that is of the root node and that serves the user equipment; query a first route mapping relationship based on the identifier of the second node to determine a third node, wherein the first route mapping relationship comprises a correspondence between the second node and the third node, and wherein the third node is a next-hop node that is indicated in the first route mapping relationship and that the first data packet reaches after passing through the apparatus; and forward the first data to the third node. - View Dependent Claims (10, 11, 12, 13, 14, 15)
