The issue of main concern in this chapter is that a component of a distributed computation may fail while other components continue to run, or a component may be unreachable because of a connection failure. In a centralized implementation the whole system fails together.
In a distributed system a process on one node may invoke an operation on another which, in turn, may invoke an operation on a third node, as shown in Figure 16.2. Any one of these nodes may crash independently of the others at any ...
