Detailed Description
The invention will now be described in further detail with reference to the drawings and to specific examples. The step numbers in the following embodiments are set for convenience of illustration only, and the order between the steps is not limited in any way, and the execution order of the steps in the embodiments may be adaptively adjusted according to the understanding of those skilled in the art.
Referring to fig. 1, a transmitting end M transmits an original data stream to a designated aggregation server S through different links, and the aggregation server S integrates received data and transmits the integrated data to a final user. If the transmitting end M transmits the original data stream P { x }, where P { x } includes n sub-data units P1, P2..pn; the n sub-data units are transmitted over a plurality of links and sent to the aggregation server S. When the sub-data units P1 to Pn are transmitted to the aggregation server S, the Time for the sub-data units P1 to Pn to reach the aggregation server S may be different due to different RTTs (Round-Trip Time) between different links. The aggregation server needs to integrate all the data units of P1 to Pn before restoring to obtain the original data stream P { x }.
To ensure that the data stream P { x } arrives completely and orderly at the aggregation server S, the multilink transmission may employ several methods: 1. the aggregation server S waits for a timeout time t w After that, it is found that the data unit Pi has not been received, a request Ri for retransmission of the data unit Pi is actively sent to the sender M. After receiving the request Ri, the transmitting end M transmits the data unit Pi again via the link. 2. The transmitting end M actively transmits multiple identical sub-data Pi to multiple links, and the aggregation server S receives the sub-data Pi from different tunnels, and discards the sub-data Pi from other links after the aggregation server receives the first complete pair of sub-data Pi. 3. The transmitting end M uses an encoding algorithm to recode the original data P { x }, and then transmits the recoded data stream Q { x }, to the aggregation server S through different links. The aggregation server S, according to a specific decoding algorithm, after receiving the complete Q { x } data stream, restores the original data stream P { x }.
In the above method 1 and method 2, the transmitting end M transmits a part of redundant data, resulting in a loss of link bandwidth, and the method 1 also relies on the retransmission feedback R of the aggregation server S, which results in a phase change to increase the data transmission time. In the method 3, the encoding and decoding algorithm often needs to consume a part of CPU resources, and if the CPU has weak computing capability, the encoding and decoding speed cannot keep up with the data transmission speed; in addition, when the transmitting end M transmits the original data, a part of the encoded message is also transmitted to the aggregation server S, which also causes a certain bandwidth loss.
As shown in fig. 2, an embodiment of the present invention provides a data transmission method for multi-link aggregation, which is applied to a transmitting end, and includes the following steps.
