Multicast has the potential to be applied in Artificial Intelligence Data Centers (AIDCs) to improve the efficiency of point-to-multipoint data transmission during large language model training and inference. This document identifies key requirements of multicast in AIDCs, and analyzes the gaps between these requirements and the capabilities of existing multicast technologies.
