With the increasing popularity of high-bandwidth applications, the need for applications capable of multi-path aggregation transmission has risen. These applications enhance bandwidth utilization and network redundancy, simultaneously optimizing network performance by employing multiple network paths. However, deploying such technology involves complex processes and necessitates advanced equipment. We propose a solution that leverages an open-source routing platform combined with multi-path aggregation transmission, aiming to enhance network performance through software upgrades rather than hardware replacement. The system comprises a proxy router and an aggregation server, which facilitate the conversion of traditional TCP traffic into multi-path aggregation transmission traffic. Experiments demonstrate that the system substantially improves transmission efficiency and network reliability for users possessing single network interfaces that lack native support for the protocol, thereby broadening the potential applications of multi-path aggregation transmission.
