Definition of dynamic loading on the firewall
Dynamic loading of the firewall refers to loading services or functions to a running system. The service or function code is loaded to the system as module-specific files after dynamic loading commands are executed. Dynamic loading enables the system to provide new or enhanced functions or services even if the system software is not upgraded, keeping the system up-to-date without interrupting service continuity. A license is required for the dynamic loading module. If the dynamic loading license is not loaded or activated, no dynamic loading module is unavailable. The dynamic loading modules of the firewall consist of content security and URL filtering packages.

Load balancing
The functions and meanings of load balancing are described as follows: When multiple routes have the same routing protocol preference and metric, these routes are called equal-cost routes, among which load balancing can be implemented. Routers support the multi-route mode, allowing you to configure multiple routes with the same destination and preference. If the destinations and costs of multiple routes discovered by the same routing protocol are the same, load balancing can be performed among the routes. Run the maximum load-balancing number command in the views of various protocols to implement load balancing. Load balancing falls into the following two modes: -Packet-by-packet When the packet-by-packet load balancing is configured, firewalls at the network layer forward packets to the same destination through various equal-cost paths. That is, switches always choose the next hop address that is different from the last one to send packets. -Session-by-session When session-by-session load balancing is configured, firewalls forward packets according to the source address, destination address, source port, destination port, and protocol contained in the packets. When the five factors are the same, firewalls always choose the same next hop address as the last one used to send the packets.
