In the emergent landscape of next-generation communication networks, multi-link operation is becoming significant for random access protocols owing to its potent multi-stream concurrent transmission capabilities. Yet, in the context of random access networks, the intricate coupling relationships among links make the stability analysis tricky. This paper considers the stability property of a multi-link slotted Aloha system, where the Cloning strategy is considered that sets up devices to transmit identical data replicas over separate links. By analyzing the state transition process of the head-of-line packet of each multi-link device, we identify distinct steady-state points and delineate the boundaries of stability regions for each link under various traffic conditions. Iterative algorithms are proposed to determine the network stability situation and the effectiveness is verified via simulation results on network access delay performance.
