This paper presents a new algorithm implementing reconfigurable atomic read/write memory for highly dynamic environments. The original RAMBO algorithm, recently developed by Lynch and Shvartsman, guarantees atomicity for arbitrary patterns of asynchrony, message loss, and node crashes. RAMBO II implements a different approach to establishing new configurations: instead of operating sequentially, the new algorithm reconfigures aggressively, transferring information from old configurations to new configurations in parallel. This improvement substantially reduces the time to establish a new configuration and to remove obsolete configurations. This, in turn, substantially increases fault tolerance and reduces the latency of read/write operations when the network is unstable or reconfiguration is bursty. This paper presents RAMBO II, a correctness proof, and a conditional analysis of its performance. Preliminary empirical studies illustrate the advantages of the new algorithm.
