....adopt a speci c fault tolerant mechanism or a small set of such, and provide the corresponding functionalities as execution primitives. The utilization of these execution primitives by the software system ranges from completely transparent access to the fault tolerant mechanism (e.g. see Alphorn [3]) to a complete set of programming primitives that allow the developer to integrate a set of fault tolerant capabilities in a custom made manner in the system (e.g. see Arjuna [52] In any case, the developer does not have to search the entire domain of existing fault tolerant mechanisms to nd ....

....of distributed programs. With RPC, a request for service from a client to a server process is structured to give synchronization semantics at the client similar to normal procedure call. Numerous examples of different RPC services and implementations exist, including Firefly RPC [19] Alphorn [3], lightweight RPC [4] and Peregrine [14] Among the commercial RPC packages released have been Courier from Xerox [24] Sun RPC [22] Netwise RPC from Novell Netware, and NCA from Apollo [2] On the surface, the semantics of RPC seem very simple, yet the reality is that there are subtleties and ....
