Explanation

Synchronization works in two modes: Full sync transfers all Security Gateway kernel table information from one cluster member to another. It is handled by the fwd daemon using an encrypted TCP connection. Delta sync transfers changes in the kernel tables between cluster members. Delta sync is handled by the Security Gateway kernel using UDP multicast or broadcast on port 8116. Full sync is used for initial transfers of state information, for many thousands of connections. If a cluster member is brought up after being down, it will perform full sync. After all members are synchronized, only updates are transferred via delta sync. Delta sync is quicker than full sync. https://sc1.checkpoint.com/documents/R76/CP_R76_ClusterXL_AdminGuide/7288.htm
