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.
Claims15
A data forwarding method, comprising:
- generating, by a first node in a 5G network, a topology relationship of the first node, wherein the topology relationship of the first node includes one or more identifiers of one or more first-type subnodes and one or more connection statuses between the first node and the one or more first-type subnodes, wherein each first-type subnode of the one or more first-type subnodes connects to a core network by using the first node, and wherein the first node connects to the core network by using a parent node of the first node;
- receiving, by the first node from the one or more first-type subnodes, topology relationship information of the one or more first-type subnodes, wherein topology relationship information of a first-type subnode of the one or more first-type subnodes includes one or more identifiers of one or more second-type subnodes and one or more connection statuses between the first-type subnode and the one or more second-type subnodes, and wherein each second-type subnode of the one or more second-type subnodes connects to the core network by using the first-type subnode;
- after receiving the topology relationship information of the one or more first-type subnodes, sending, by the first node to the parent node of the first node, the received topology relationship information of the one or more first-type subnodes and the generated topology relationship of the first node;
- receiving, by the 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.
4 more elements
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:
- generate a topology relationship of the apparatus, wherein the apparatus is a node in a 5G network, wherein the topology relationship of the apparatus includes one or more identifiers of one or more first-type subnodes and one or more connection statuses between the apparatus and the one or more first-type subnodes, wherein each first-type subnode of the one or more first-type subnodes connects to a core network by using the apparatus, and wherein the apparatus connects to the core network by using a parent node of the apparatus;
- receive, from the one or more first-type subnodes, topology relationship information of the one or more first-type subnodes, wherein topology relationship information of a first-type subnode of the one or more first-type subnodes includes one or more identifiers of one or more second-type subnodes and one or more connection statuses between the first-type subnode and the one or more second-type subnodes, and wherein each second-type subnode of the one or more second-type subnodes connects to the core network by using the first-type subnode;
- after receiving the topology relationship information of the one or more first-type subnodes, send, to the parent node of the apparatus, the received topology relationship information of the one or more first-type subnodes and the generated topology relationship of the apparatus;
- 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.
