Abstract

The invention relates to a multipath congestion control method and device based on time delay and window jitter. The multi-path congestion control method based on time delay and window jitter comprises the following steps: obtaining a characteristic value R (k) of current network delay jitter according to a product of a difference value between data round-trip time delay and a data round-trip timedelay average value on a current transmission path and a first weight value; obtaining the average value of the size of the congestion window on the current transmission path and the sizes of the previous n congestion windows, and obtaining the characteristic value w (k) of the jitter of the current congestion window according to the product of the difference value between the congestion window value and the average value of the previous n congestion windows and the second weight value; determining the current packet loss type on the data transmission path by using the result of the sum of R(k) and w (k); and adjusting a congestion window corresponding to the data sending path according to the packet loss type. According to the multi-path congestion control method based on the time delayand the window jitter, the effective throughput of the MPTCP of the mobile terminal is improved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a multipath congestion control method and device based on delay and window jitter. Background technique [0002] With the rapid development of broadband wireless mobile communication technology and continuous innovation of Web application technology, mobile Internet has become another driving force for Internet development after broadband technology, providing a new platform for Internet development. Although there are already a variety of network transmission resources and access methods, due to the defects of the TCP protocol, only one-path transmission is supported. Whether it is a mobile or PC device, although it has multiple network interfaces, each terminal device connects at the same time. Only one network card can establish a connection to provide services. [0003] In order to improve the network transmission function and effectively redundant the bandwidth...
