A consistent history link connectivity protocol

Abstract

Given the prevalence of powerful personal workstations connected over local area networks, it is only natural that people are exploring distributed computing over such systems. Whenever systems become distributed the issue of fault tolerance becomes an important consideration. In the context of the RAIN project (Reliable Arrays of Independent Nodes) at Caltech, we have been looking into fault tolerance in several elements of the distributed system. One important aspect of this is the introduction of fault tolerance into the communication system by introducing redundant network elements and redundant network interfaces.
