Abstract
A data communication method, where a first device receives a request message from at least one second device, where the request message requests the first device to forward group data, and the request message carries a group identifier. The first device returns a response message to the at least one second device, where the response message carries a layer-2 address and an Internet Protocol (IP) address corresponding to the group identifier, and the first device sends the group data using the layer-2 address when receiving the group data sent by a third device to the IP address.
Claims20
A data communication method, comprising:
- receiving, by a first device, a request message from at least one second device, wherein the request message requests the first device to forward group data, and wherein the request message carries a group identifier;
- returning, by the first device, a response message to the at least one second device, wherein the response message carries a layer-2 address and an Internet Protocol (IP) address corresponding to the group identifier;
- and
- sending, by the first device, the group data using the layer-2 address when receiving the group data from a third device to the IP address.
A first device, comprising:
- a processor;
- a memory coupled to the processor;
- and
- a transceiver coupled to the processor;
- wherein the memory is configured to store an instruction,
- wherein the processor is configured to invoke and execute the instruction stored in the memory, and
- wherein the transceiver is configured to:
- receive a request message from at least one second device, wherein the request message requests the first device to forward group data, and wherein the request message carries a group identifier;
- send a response message to the at least one second device, wherein the response message carries a layer-2 address and an Internet Protocol (IP) address corresponding to the group identifier;
- and
- send the group data using the layer-2 address when receiving the group data from a third device to the IP address.
