Problems solved by technology

At present, there are many protocols for multi-path or parallel multi-path, for example, ATLB, PATTHEL, R-MTP, cTCP, CMT-SCTP, etc., but almost every protocol has its inherent weaknesses, resulting in no Large-scale applications, therefore, require a new approach to path management

Embodiment Construction

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0031] MPTCP (MultiPath Transport Control Protocol) is an extension of traditional TCP, which efficiently transmits data through multiple paths between communication source and destination nodes, providing end-to-end reliable, orderly and fast data transmission . Compared with the traditional TCP, the MPTCP protocol has two remarkable features: 1) Improve the throughput of the network. Since MPTCP uses multiple paths to transmit data at the same time, the amount of ...

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, ...
