Problems solved by technology
The MPTCP and CMT-SCTP protocol stacks are oriented to best-effort transmission scenarios, using best-effort multi-link allocation algorithms to achieve maximum throughput, which will cause some links to be overloaded due to the inaccuracy of load allocation. Or rapid changes in link quality cannot respond quickly, resulting in data packet loss and unstable arrival delays
[0008] To sum up, it can be seen that there are certain defects in the current link aggregation technology, and the above defects are especially obvious when transmitting real-time communication.

Embodiment Construction
[0022] In order to make the purpose, technical solutions, and advantages of the embodiments of the present application clearer, the embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings. Here, the exemplary embodiments of the application and their descriptions are used to explain the application, but not to limit the application.
[0023] Real-time application communication, such as video telephony, video conferencing, video interaction, video surveillance, interactive live broadcast, video on demand, video multicast, real-time application communication often requires stable network, low jitter, stable delay, low delay, and large burst The traffic response is fast, and the transmission code stream is relatively regular, such as a constant code rate, or fluctuates within a certain range. The characteristic of this type of application communication is that when the sending device distributes the load to dif...

The present application discloses a method and a sending device for multi-link aggregation transmission data. The method includes: acquiring link parameters, and determining the transmission performance level of each link according to the link parameters. The link parameters include link parameters Bandwidth, delay, packet loss rate, window size and round-trip delay RTT; calculate the bandwidth capacity of each link among all links with the highest transmission performance level according to the window size and RTT; for each data packet to be transmitted, according to The bandwidth capacity randomly selects a link from all the links with the highest transmission performance level as the target link for transmitting the current data packet. Among them, the link with the larger bandwidth capacity has a higher probability of being selected as the target link. When the link After being selected as the target link to send a data packet, the bandwidth capacity of the link is reduced accordingly; the current data packet is transmitted through the target link. The application can reduce network delay, stabilize traffic, and meet the requirements of high stability and high fault tolerance for real-time transmission.
Description
technical field [0001] The present application relates to the technical field of network data transmission, and in particular to a method and a sending device for multi-link aggregation data transmission. Background technique [0002] This section is intended to provide a background or context to embodiments of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] Reasonable aggregation and use of multiple network links can obtain greater bandwidth and better fault tolerance. Existing link aggregation technologies include Link Aggregation Control Protocol (Link Aggregation Control Protocol, LACP) based on the link layer, multiple transmission control protocol (MultiPath TCP, MPTCP) based on the transmission control layer, and flow control transmission protocol ( Stream Control Transmission Protocol, SCTP) and so on. [0004] Such protocols often have certain limitations. For example, t...
