Cybertwin-Aided Transmission for Cloud-Native Applications in Multi-Homing Wireless Networks

Multi-homed devices, designed to adapt to the heterogeneous wireless networks, have been available for users. However, practical challenges such as inadequate support from applications, hinder users from fully leveraging the multi-homing feature to enhance their service quality. Considering the undergoing evolution of applications towards cloud-native paradigm, we propose a Cybertwin-aided multi-application transmission scheme. It can fully reap the benefits of multi-homing transmission while mitigating the inherent limitations in traditional multi-path protocols. This is achieved through utilizing the socalled Cybertwin service as the communication agent for all cloud-native applications of the user. We multiplex different applications over the always-on multi-homing connections of Cybertwin service, leveraging the stream feature of Quick UDP Internet Connection (QUIC). We further support seamless stream migration between these connections to handle link fluctuation. We conduct extensive experiments under a test environment deployed in the real world and demonstrate the superiority of our scheme in realizing more efficient and stable transmission.
