To represent more complex bonding scenarios, SIA is configured with a hierarchy of ports, links, and connection bundles. In our case, we started by creating links for v.90 dial-up access. When using identical modems and a login authorized for multiple active connections, links can be associated with several ports, using the first available. Next, we combined links into connection bundles . After completing this wizard, results are visible from the Advanced Summary page .
Dynamic activation is controlled by bundle bandwidth.
In the example shown here, another call is placed if any link exceeds 60 percent utilization for 30 seconds. If any link transfers less than 20 percent of its capacity for 60 seconds, that call is dropped. To prevent hysteresis, whenever bandwidth changes, the ePipe waits for a stabilize period before making further decisions. It is easy to put a bundle into place with basic settings, but most users will optimize these parameters over time. We experimented with dynamic links, but ran performance tests with static links to ensure consistent bandwidth.
