Improved utilization of connections that can be either available or blocked is provided by associating an atemporal connection state with each connection. If a connection is available, messages are transmitted on the connection normally. If a connection is blocked, the atemporal connection state is updated to reflect the changes that were made but not transmitted. In this manner, a record is kept that allows correct transmission of the information when the connection comes back up. More specifically, after a connection status changes from blocked to available, recovery messages are automatically generated from the atemporal connection state and transmitted on the connection.
