Timeouts• Possible options on timeout of DoOperation:• return with error indication• relies on application-level interpretation• not appropriate if operation must be redone, since the newattempt will have a different requestId (possible source ofduplicate requests)• multiple retry• re-invokes DoOperation with same message until success or“reasonably certain” problem due to server failure• returns with server failure indication (throws Exception)
