Which Correction mechanisms are available with ClusterXL under R81.10?
Under R81.10, ClusterXL employs Dispatcher (Early Correction) and Firewall (Late Correction) as its correction mechanisms. The Dispatcher ensures initial packet direction, while the Firewall addresses any necessary corrections at a later stage.
Starting with R80.20 "SDF" mechanism has been deprecated. Stickiness is now achieved via the new Cluster Correction Layer (CCL). See section "3" in the following link. https://support.checkpoint.com/results/sk/sk169154

The Cluster Correction Layer (CCL) is a mechanism that deals with asymmetric connections. The CCL provides connections stickiness by "correcting" the packets to the correct Cluster Member: - In most cases, the CCL makes the correction from the CoreXL SND. - In some cases (like Dynamic Routing, or VPN), the CCL makes the correction from the Firewall or SecureXL.
It's done by CCL, dispatcher and firewall
I believe this is C.
