CoreXL SND
Secure Network Distributer. Part of CoreXL that is responsible for: Processing incoming
traffic from the network interfaces; Securely accelerating authorized packets (if
SecureXL is enabled); Distributing non-accelerated packets between Firewall kernel
instances (SND maintains global dispatching table, which maps connections that were
assigned to CoreXL Firewall instances). Traffic distribution between CoreXL Firewall
instances is statically based on Source IP addresses, Destination IP addresses, and the
IP 'Protocol' type. The CoreXL SND does not really "touch" packets. The decision to
stick to a particular FWK daemon is done at the first packet of connection on a very high
level, before anything else. Depending on the SecureXL settings, and in most of the
cases, the SecureXL can be offloading decryption calculations. However, in some other
cases, such as with Route-Based VPN, it is done by FWK daemon.
