7. If the attempt to reach the primary DLUS is unsuccessful, attempt to reach
the backup DLUS.
Example:
– Assume the following parameter values:
-
Delay before initiating retries
= 120 sec
-
Perform short retries to restore disrupted pipe
= yes
-
Short retry timer
=60sec
-
Short retry count
=2
-
Perform long retries to restore disrupted pipe
= yes
-
Long retry timer
= 300 sec
– Pipe activation fails.
– Wait 120 seconds (the value of
Delay before initiating retries
).
– Retry the primary DLUS and, if this fails, retry the backup DLUS.
– If retry fails, wait 300 seconds (the value of
Long retry timer
), retry the primary
DLUS,and if this retry fails, retry the backup DLUS.
– If retries fail, continue to retry the primary and backup DLUS, waiting 300
seconds between retry sequences, for as long as the DSPU is requesting
ACTPU.
v For all other cases of pipe failure, DLUR will try the primary DLUS and then the
backup DLUS immediately. If this fails, DLUR will:
1. Wait for the amount of time specified by the minimum of the
short retry timer
and the
Delay before initiating retries
parameters.
2. Attempt to reach the primary DLUS.
3. If the attempt to reach the primary DLUS is unsuccessful, attempt to reach
the backup DLUS
4. If pipe activation continues to fail, DLUR will retry as described in steps1-3
for the number of times specified in the
short retry count
.
If the
short retry count
is exhausted, DLUR will retry as defined in steps5-7
as long as the DSPU is requesting ACTPU.
5. Wait for the amount of time specified by the
Long retry timer
Note: If
Perform long retries to restore disrupted pipe
is No, no further retries
will be attempted.
6. Attempt to reach the primary DLUS.
7. If the attempt to reach the primary DLUS is unsuccessful, attempt to reach
the backup DLUS.
Example:
– Assume the following parameter values:
-
Delay before initiating retries
= 120 sec
-
Perform short retries to restore disrupted pipe
= yes
-

-
