3.3.5 Timer Events
Connection schedules define a set of timers that trigger connection session establishments and tear-downs.
If a connection session is not established and the connection schedule indicates that File Replication Service (FRS) has to replicate (see section 2.3.1.2), a timer MUST be fired to instruct FRS to go through a connection session establishment process to setup a connection session (join).
If a connection session is established (joined) and the connection schedule indicates that FRS has to not replicate (see section 2.3.1.2), a timer MUST be fired to instruct FRS to tear down the joined connection.
The connection session establishment process (join) (see section 3.3.4.6) is a handshake between two existing partners before they begin replicating. The process begins after any of the following events:
Connection schedule opens.
FRS is started while the schedule is open.
Connection session is being re-established after loss of network connectivity or a server shutdown while the schedule is open.
