Researches Advanced in Reliable Low Latency Transmission Based on Multi-links

Recently, applications that require reliable low latency transmission have attracted increasing attention from various domains, such as industrial automation of Industry 4.0, and V2X-communications of intelligent transportation. Meanwhile, with the development of communication technologies such as 5G and WiFi, terminal devices or servers typically have multiple network interfaces and multi-links network access capabilities. In this paper, we provide a comprehensive review of recent advances in reliable low latency transmission based on multi-links. First, we introduce the multi-links transmission and its function. Then, we introduce three types of methods, including packet duplication, network coding, dynamic selection, and their combination for reliable low latency transmission based on multi-links. Finally, we conclude the limitations and challenges of reliable low latency transmission with multi-links in uncertain network environments, and discuss new trends and potential directions for future study.
