Coordination I
So if we now have our distributed system where we hardly can tell what time it is, how do we coordinate our actions? Simple things as taking a lock to protect critical operations is if not tricky, time consuming. A special case occurs if we loose our leader, can a new leader be elected and what happens in the case of node failures.
Multi-casting is also a coordination problem. It does not look like one at first sight but it turns out that processes have to agree on the order of arriving messages or if a arrived message should be treated at all.
