5.5.6 Increasing Requirements for Adding Additional Band-
width
The SCS will periodically measure how much bandwidth a particular port is using. The period of time
during which this measurement is taken may be configured differently for each site. When the measurement
period is short, a temporary increase in network traffic may cause the site to bring up additional connections
to increase bandwidth, increasing cost. If a site's bandwidth utilization is measured (averaged) over a longer
period of time, a temporary increase in network traffic will have less impact on whether or not additional
bandwidth is added.
Another way to reduce cost is to increase the percentage utilization required to add additional connections.
If a site is permitted to use up to 80% of the total currently-dialed bandwidth on a particular port (rather than,
for example, 25%), the site will be less likely to require additional connections to increase bandwidth.

5.5.7 Controlling Frequency of Calls

The success and failure timers can be used to control how aggressive the SCS will be when attempting
connections. Two commands control this behavior.
Define Site Time Success sets the time lapse between attempts to connect to a remote site after a
successful connection has been made.
Define Site Time Failure sets the time lapse between attempts to connect to a remote site when a
connection attempt fails.
If the last connection attempt succeeded and the success timer is set to a high value (for example, 20
minutes), the SCS will wait for a longer period of time before attempting a new connection. If the SCS was
not able to connect for some reason, setting the failure timer to a low value (for example, 5 seconds) will
cause the SCS to retry the connection at short intervals until it succeeds.
In Figure 5-20, the SCS is configured to allow a new connection attempt almost immediately upon
completion of a successful connection. If the last attempt to connect to the site failed, the SCS will wait 30
seconds before attempting another connection. It will continue to retry the connection every 30 seconds until
it succeeds.
