Allocating Bandwidth to Applications Not Controlled by SRC ACP
If you control the bandwidth of some applications by means of SRC ACP, you can accommodate the applications that are not controlled by SRC ACP by assigning background bandwidths for the edge congestion points. The background bandwidth is the total bandwidth allocated to the applications for which bandwidth is not controlled by SRC ACP.
Because the total background bandwidth is unlikely to be used at a particular time, you can also specify a tuning factor that provides an estimation of the fraction of the background bandwidth that will be used. You can configure multiple values for the background bandwidth with corresponding tuning factors.
