STEP THREE
Up to this point, the configuration can be used either for link back up or for load back up. This example shows
link back up, but parameters applicable to load back up will be mentioned when they appear. Complete
information on the multilink circuit concept is provided in chapter 4 of the CyROS Reference Guide.

Parameter
Example Your Application
Criterion for Traffic
Distribution This parameter has no effect for link backup. For load
backup,
Optimal distribution is performed randomly, and the
packet is forwarded to the interface with the lesser load.
Address Based distribution is used when the receiver cannot
reorder packets, and all packets to a certain IP address must
be sent through the same interface. This distribution method is
not recommended unless absolutely necessary.
Bandwidth Upper
Limit Zero for link backup. For load backup, this defines when load
backup should activate the backup link. It is measured as a
percentage of the bandwidth defined in step four.
Time to Activate
Backup if Above Limit This parameter does not appear for link backup. Time until
backup is activated after main link bandwidth exceeds limit
defined in last parameter.
Bandwidth Lower
Limit This parameter has no effect for link backup. For load
backup, this defines when load backup should deactivate the
backup link. It is measured as a percentage of the bandwidth
defined in step four.
Time to Deactivate
Backup if Below Limit This parameter does not appear for link backup. Time until
backup is deactivated after main link bandwidth exceeds limit
defined in last parameter.
