Abstract

A data transmission method and a router, which are used to obtain a load sharing scheme according to current status information of a network, and perform data transmission according to the load sharing scheme in order to improve data transmission efficiency, where the method includes communicating, by a first router, with a second router over multiple radio links, acquiring, by the first router, status information of each radio link, determining a transmission overhead of each radio link according to the status information of each radio link, determining load sharing of each radio link according to the transmission overhead of each radio link, and sending data to the second router according to the load sharing of each radio link.

First claim

What is claimed is:

1 . A data transmission method, comprising:
communicating, by a first router, with a second router over multiple radio links; acquiring, by the first router, status information of each radio link; determining, by the first router, a transmission overhead of each radio link according to the status information of each radio link; determining, by the first router, load sharing of each radio link according to the transmission overhead of each radio link; and sending, by the first router, data to the second router according to the load sharing of each radio link.

2 . The method according to claim 1 , wherein acquiring, by the first router, the status information of each radio link comprises receiving, by the first router, the status information of each radio link that is sent by the second router.

3 . The method according to claim 1 , wherein the status information comprises a network standard and a received signal strength indicator (RSSI), and wherein determining, by the first router, the transmission overhead of each radio link according to the status information of each radio link comprises:
determining, by the first router, a weight corresponding to the network standard of each radio link and another weight corresponding to the RSSI of each radio link; and determining, by the first router, the transmission overhead of each radio link according to the weight corresponding to the network standard of each radio link and the other weight corresponding to the RSSI of each radio link.

4 . The method according to claim 3 , wherein the status information further comprises connection duration of the radio link, and wherein determining, by the first router, the transmission overhead of each radio link according to the status information of each radio link comprises:
determining, for each radio link, by the first router, whether the connection duration of the radio link exceeds a monthly duration quota; and using, by the first router, a preset upper limit of the transmission overhead as the transmission overhead of the radio link when the connection duration exceeds the monthly duration quota.

5 . The method according to claim 3 , wherein the status information further comprises statistics traffic of the radio link, and wherein determining, by the first router, the transmission overhead of each radio link according to the status information of each radio link comprises:
determining, for each radio link, by the first router, whether the statistics traffic of the radio link exceeds a monthly traffic quota; and using, by the first router, a preset upper limit of the transmission overhead as the transmission overhead of the radio link when the statistics traffic exceeds the monthly traffic quota.

6 . The method according to claim 3 , wherein the status information further comprises connection duration of the radio link, and wherein determining, by the first router, the transmission overhead of each radio link according to the status information of each radio link comprises:
determining the weight corresponding to the network standard of the radio link and the other weight corresponding to the RSSI of the radio link when the connection duration does not exceed a monthly duration quota; and determining the transmission overhead of the radio link according to the weight corresponding to the network standard of the radio link and the other weight corresponding to the RSSI of the radio link.

7 . The method according to claim 3 , wherein the status information further comprises statistics traffic of the radio link, and wherein determining, by the first router, the transmission overhead of each radio link according to the status information of each radio link comprises:
determining the weight corresponding to the network standard of the radio link and the other weight corresponding to the RSSI of the radio link when the statistics traffic does not exceed a monthly traffic quota; and determining the transmission overhead of the radio link according to the weight corresponding to the network standard of the radio link and the other weight corresponding to the RSSI of the radio link.

8 . The method according to claim 1 , wherein after determining, by the first router, the load sharing of each radio link according to the transmission overhead of each radio link, the method further comprises sending, by the first router, an indication message that comprises the load sharing of each radio link to the second router such that the second router sends data according to the load sharing of each radio link.

9 . A first router, comprising:
a processor; a memory; and a communications interface, wherein the processor, the memory, and the communications interface are connected to each other, wherein the memory is configured to store a program, wherein the communications interface is configured to communicate with a second router, and wherein the processor executes the program stored by the memory to implement data transmission, which comprises the following operations:
communicate with the second router over multiple radio links;
acquire status information of each radio link;
determine a transmission overhead of each radio link according to the status information of each radio link;
determine load sharing of each radio link according to the transmission overhead of each radio link; and
send data to the second router according to the load sharing of each radio link.

10 . The first router according to claim 9 , wherein acquiring the status information of each radio link comprises receiving the status information of each radio link that is sent by the second router.

11 . The first router according to claim 9 , wherein the status information comprises a network standard and a received signal strength indicator (RSSI), and wherein determining the transmission overhead of each radio link according to the status information of each radio link comprises:
determining a weight corresponding to the network standard of each radio link and another weight corresponding to the RSSI of each radio link; and determining the transmission overhead of each radio link according to the weight corresponding to the network standard of each radio link and the other weight corresponding to the RSSI of each radio link.

12 . The first router according to claim 11 , wherein the status information further comprises connection duration of the radio link, and wherein determining the transmission overhead of each radio link according to the status information of each radio link comprises:
determining, for each radio link, whether the connection duration of the radio link exceeds a monthly duration quota; and using a preset upper limit of the transmission overhead as the transmission overhead of the radio link when the connection duration exceeds the monthly duration quota.

13 . The first router according to claim 11 , wherein the status information further comprises statistics traffic of the radio link, and wherein determining the transmission overhead of each radio link according to the status information of each radio link comprises:
determining, for each radio link, whether the statistics traffic of the radio link exceeds a monthly traffic quota; and using a preset upper limit of the transmission overhead as the transmission overhead of the radio link when the connection duration exceeds the statistics traffic exceeds the monthly traffic quota.

14 . The first router according to claim 11 , wherein the status information further comprises connection duration of the radio link, and wherein determining the transmiss
