Multi-link research involves the study and development of systems or networks that utilize multiple links or connections to achieve improved performance, reliability, and efficiency. This can encompass various fields such as telecommunications, networking, and transportation, where the use of multiple links can enhance data transmission speeds, fault-tolerance, and load balancing. Researchers in this area often explore ways to optimize the allocation of resources across multiple links, improve connectivity between different nodes, and enhance overall network performance. Multi-link research is crucial for developing robust and resilient systems that can effectively handle the increasing demands of modern communication and data processing.
