The standard resequencer is useful for applications that use identifiers from a simple numeric identifier sequence in their messages. The standard resequencer receives a stream of messages that might not arrive in order; it then stores the out-of-sequence messages until a complete sequence based on the sequence IDs is received. The in-sequence messages are then processed asynchronously based on their sequence ID.

It is important to note that the messages to outbound services of the standard resequencer Mediator service component are guaranteed to arrive in sequence.
