| ### idempotent semantics RPC: A characteristic of a procedure in which executing it more than once with identical input always produces the same result, without any undesirable side effects; for example, a procedure that reads a particular block of an immutable file is idempotent. DCE RPC supports maybe and broadcast semantics as special forms of idempotent operations. See also at_most_once semantics, broadcast semantics, maybe semantics. ###
