9.2 Circuit Manager Properties
The circuit manager must have sufficient functionality to be able to
compensate for the lack of periodic KEEPALIVE messages:
- It must be able to determine link layer unreachability in a
predictable finite period of a failure occurring.
- On determining unreachability it should:
- start a configurable dead timer (comparable to a
typical Hold timer value).
- attempt to re-establish the Link Layer connection.
- If the dead timer expires it should:
- send an internal circuit DEAD indication to TCP.
- If the connection is re-established it should:
- cancel the dead timer.
- send an internal circuit UP indication to TCP.
