In Check Point firewall, the default Distribution mode is Auto-topology. Auto-topology uses the built-in algorithm to automatically determine the best way to distribute the traffic across the firewall cluster, based on the topology of the network and the current load on the cluster members.
Auto-topology takes into account the available bandwidth and the CPU utilization of each cluster member, and then makes decisions on how to distribute the traffic across the cluster in real-time. It is a dynamic and adaptive mode that ensures the best use of the available resources and the highest level of performance.
