Abstract

We study reliability in the all-optical Partitioned Passive Stars (POPS) topology. POPS is a physical architecture to scale the t raditional optical passive star couplers and explore the advantages of high noise immunity and single-hop. The reliability and fault tolerance in POPS rely on its connectivity. In this study, we analyze the worst case for network partitions due to either node failures or link errors. For node connectivity, we show that the whole system remains connectivity no matter how many nodes don't work. For link connectivity, we analyzed some worst cases due to link errors and the lower bound for connectivity is demonstrated. Some sufficient approaches are proposed to detect and keep connectivity of the whole system.
