Link Optimization Method Based on Cellular Link Aggregation

Abstract

The invention discloses a link optimization method based on cellular link aggregation, which mainly solves the problems of poor cellular link aggregation effect and slow transmission rate in the prior art. It includes: 1) Obtaining the state information of each cellular link, judging whether each link is in a fault state, setting the faulty link as a backup link, and setting the remaining links as the main link; 2) monitoring the main link According to the network standard of each cellular module in the network, 3G and 4G network links are preferred as the main link; 3) Allocate bandwidth to each link through signal strength, and obtain the transmission bandwidth of each link b i And the average transmission rate v in the period i , calculate the bandwidth utilization rate u of each link i ; 4) By comparing the bandwidth utilization rate u of each link in each timing cycle i The main and backup links are switched according to the size of the minimum bandwidth utilization rate m; 5) Repeat the above steps until the transmission is completed. The invention can ensure real-time selection of the optimal link, and quickly and efficiently complete the data transmission of multi-cellular link aggregation.

Description

technical field [0001] The invention belongs to the technical field of communication, and proposes a link optimization method based on cellular link aggregation, which effectively improves the aggregation efficiency of multi-cellular links and realizes efficient data transmission of multi-cellular links. Background technique [0002] In network technology, in order to ensure the stability and reliability of links between devices and increase the transmission rate, link aggregation technology is usually used to bundle multiple physical links into one logical link to expand the bandwidth of the link. At the same time, each physical link is mutually redundant, and when some links fail, they can be switched to other links to carry services. [0003] Existing link aggregation solutions are mostly used in wired data switching networks such as Ethernet. Due to the high stability of the wired network, a simple link aggregation scheme such as static trunk or dynamic LACP can achieve...

Problems solved by technology

[0005] However, because the mobile Internet is affected by factors such as network coverage, signal strength, signal interference, and object occlusion, its network stability is poor, and data transmission fluctuates greatly.

If you use the same link aggregation scheme as the wired network, the link aggregation effect will be poor, even worse than the transmission effect when using a single link
