The round-robin algorithm

The round-robin algorithm assumes that all CICS® regions are equally valid for selection. In the round-robin algorithm, when the Client daemon is initially started, it reads from the configuration file a list of all possible CICS regions to which any ECI or EPI request can be sent.

The Workload Manager also records the last region selected. When a new ECI or EPI request is made, the next region in the list is selected as the target. When it reaches the last region it loops around to the first one.
