Consider a SunRPC client sending a request to a server. (a) Under what circumstances can the client be sure its request has executed exactly once? (b) Suppose we wished to add at-most-once semantics to SunRPC. What changes would have to be made? Explain why adding one or more fields to the existing headers would not be sufficient.
