Abstract

The invention discloses a path management method and device based on the multi-path transmission protocol MPTCP, wherein the method includes: obtaining the transmission status information of each TCP sub-path in the MPTCP connection; The QOS value of the TCP sub-path; determine the TCP sub-path whose transmission quality deteriorates according to the QOS value, and then set the TCP sub-path to a standby state. The method and device of the present invention can quantify the communication quality of each path as QoS according to the performance comparison of each path, and detect the path whose communication quality changes during the communication process through the value of QoS, and analyze each path in real time. The path parameters of MPTCP ensure that the transmission path used in the network can achieve the maximum throughput and bandwidth utilization, make the network throughput change more smoothly, and improve the link utilization, throughput and robustness of MPTCP.

Description

technical field

[0001] The invention relates to the technical field of network data transmission, in particular to a path management method and device based on a multipath transmission protocol MPTCP. Background technique

[0002] Currently, parallel multiplexing has attracted extensive attention from academia and industry because of its unique advantages in aggregating bandwidth, balancing loads, and improving network robustness. Research on CMT technology focuses on the application layer, transport layer and network layer. However, as the bottom layer with end-to-end path information, the transport layer is the most suitable layer for deploying CMT. At the transport layer, the terminal system can use the status information of each path: bandwidth, congestion status, delay, etc. Used to divert traffic from congested paths to non-congested paths. With the development of multiple access technologies, smart mobile terminals have become more and more popular in recent years, ...
