Let's see. - Byzantine General's Problem (Consensus in a distributed system) - Part time Parliament (Paxos Algorithm also reaching consensus in a distributed system) - Confused Deputy - Gossip Protocol(Quickly spread state in a distributed system) - Vector Clocks ( Determine a partial ordering of events in a distributed system) Many of these concepts were given clever names given by Leslie Lamport who did a lot of Distributed Systems Research.
