Chapter 14 Trunks Table 89 Configuration > Network > Interface > Trunk > Add (or Edit) (continued) LABEL DESCRIPTION Egress Bandwidth This field displays with the least load first or spillover load balancing algorithm.It displays the maximum number of kilobits of data the ZyWALL is to send out through the interface per second. Spillover This field displays with the spillover load balancing algorithm. Specify the maximum bandwidth of traffic in kilobits per second (1~1048576) to send out through the interface before using another interface. When this spillover bandwidth limit is exceeded, the ZyWALL sends new session traffic through the next interface. The traffic of existing sessions still goes through the interface on which they started. OK Cancel The ZyWALL uses the group member interfaces in the order that they are listed. Click OK to save your changes back to the ZyWALL.

A queue is given an amount of bandwidth irrespective of the incoming traffic on that interface. This queue then moves to the back of the list. The next queue is given an equal amount of bandwidth, and then moves to the end of the list; and so on, depending on the number of queues being used. This works in a looping fashion until a queue is empty. ZyWALL USG 100/200 Series User's Guide 375
