4.2 Abort Scenario
This scenario describes an example of the protocol running to failure due to the user on the Share Receiver declining a message to receive the OPC package. This makes the assumption that the NFPB protocol is triggered by the underlying transport and runs to completion, producing Session objects on both the Share Sender and Share Receiver systems running this protocol. After the Session objects are created, the user on the Share Receiver is given the opportunity to decline, and does so.
In this example, the Share Sender is prepared to share an OPC file, but because it is declined, its length is ignored.
