Problems solved by technology

[0004] Periodic bursts of traffic and methods of offloading from interfaces with higher energy consumption to other interfaces cannot effectively utilize bandwidth resources, nor do they take into account the transmission delay of links, so that the aggregation advantages of MPTCP cannot be fully realized. Significantly reduced performance in terms of throughput and transfer time

Abstract

Embodiments of the present invention provide an energy efficiency-based MPTCP congestion control method and device, the method including: for each subflow, if the confirmation information of this transmission is received, according to the round-trip time of this transmission, and the determined Determine the expected allocation ratio of the congestion window by maximizing the subflow rate allocation results of energy efficiency; determine the second congestion window increment according to the difference between the expected allocation ratio of the congestion window and the actual allocation ratio of the congestion window, and combine the first Congestion window increment, update the current congestion window value, and use the updated congestion window value for the next data transmission. This method allows the adjustment of the congestion mechanism to consider energy efficiency factors. On the basis of ensuring the throughput performance, part of the data flow is transferred to the path with less energy consumption for transmission, so as to achieve the energy saving goal of the device, and then on the basis of ensuring the aggregation advantages of MPTCP Significantly reduce energy consumption.

Description

technical field [0001] The invention relates to the communication field, in particular to an energy efficiency-based MPTCP congestion control method and device. Background technique [0002] In the Multipath TCP (MPTCP for short), the congestion control mechanism is the core part, and the improvement of the congestion control is an important method to improve the performance of the protocol. The multi-path congestion control mechanism aims to improve the utilization rate of subflows, maximize the use of network resources, and avoid the occurrence of congestion collapse. The multipath transmission provided by MPTCP can significantly improve the throughput of mobile terminals. However, multipath transmission needs to consume more energy to maintain multiple interfaces, which is a huge challenge for battery-powered mobile devices. The limited battery capacity of mobile devices determines the duration and reliability of MPTCP connections. Therefore, when using MPTCP for concur...
