Detailed Description
The invention is described in further detail below with reference to the figures and the specific embodiments. The step numbers in the following embodiments are provided only for convenience of illustration, the order between the steps is not limited at all, and the execution order of each step in the embodiments can be adapted according to the understanding of those skilled in the art.
Referring to fig. 1, a sending end M sends an original data stream to a designated aggregation server S through different links, and the aggregation server S integrates the received data and sends the integrated data to a final user. If the sending end M sends an 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 through Pn are transmitted to the aggregation server S, the sub-data units P1 through Pn may arrive at the aggregation server S at different times due to different RTT (Round-Trip Time) between different links. The aggregation server needs to integrate all data units P1 to Pn before restoring the original data stream P { x }.
In order to ensure that the data stream P { x } reaches the aggregation server S completely and orderly, the multilink transmission may use the following methods: 1. the aggregation server S waits for a timeout twAnd then finds that data unit Pi is not received, it actively sends a request Ri for retransmission of data unit Pi to the sending end M. After receiving the request Ri, the transmitting end M transmits the data unit Pi again through the link. 2. The sending end M actively sends a plurality of same sub data Pi to a plurality of links, the aggregation server S receives the sub data Pi from different tunnels, and after receiving the first complete sub data Pi pair, the aggregation server discards the following sub data Pi from the aggregation serverThe sub-data units Pi of the other links. 3. The sending end M re-encodes the original data P { x } using a coding algorithm, and then sends the re-encoded data stream Q { x } to the aggregation server S through a different link. The aggregation server S, after receiving the complete Q { x } data stream according to a specific decoding algorithm, restores to obtain the original data stream P { x }.
In the above method 1 and method 2, the sending end M sends a part of redundant data, which causes loss of link bandwidth, and the method 1 also relies on retransmission feedback R of the aggregation server S, which results in phase change and increases the transmission time of data. In the method 3, the coding and decoding algorithm usually needs to consume a part of CPU resources, and if the CPU operation capability is not strong, the coding and decoding speed cannot keep up with the data transmission speed; moreover, when sending the original data, the sending end M also sends a part of the encoded message to the aggregation server S, which also causes a certain bandwidth loss.
