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 (MultiPathTransportControlProtocol, multipath transmission protocol) is an extension of traditional TCP, which efficiently transmits data through multiple paths between communication source and destination nodes, and provides 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 a...

Abstract

The invention discloses an MPTCP path management method based on a multi-path transmission protocol and a device. The MPTCP path management method based on the multi-path transmission protocol comprises steps of obtaining transmission state information of each TCP sub-path in MPTCP connection, calculating the QOS value of each TCP sub-path in the MTCP connection based on the transmission state, determining the TCP sub-path where the transmission quality is deteriorated according to the QOS value, and setting the TCP sub-path as a standby state. The method and device of the invention can quantify the communication quality of each path as QoS according to the performance comparison of each path, detects the path where the communication quality is changed during the communication process, can analyze the path parameter of each MPTCP path in real time, guarantees that the transmission path used in the network can realize the maximum handling capacity and the bandwidth utilization, enables the network handling capacity to change smoothly, and improves the link utilization rate, the handling capacity and the robustness of the handling capacity.

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, ...
