Assigns service requests to servers at random.
B.
Ensures that incoming requests are handled by the server with the fastest response time.
C.
Measures the load on each server to determine which server has the most available resources.

Load-Balancing Methods
ConnectControl distributes network traffic to load-balanced servers according to predefined balancing methods, which include:
*. Server Load: Measures the load on each server to determine which server has the most available resources to service a request. Each server in the group runs a load measuring agent that automatically reports the current system load to ConnectControl on the Security Gateway. Server Load is a good choice if your servers run other demanding applications in addition to supporting your load-balanced application. See also Load Measuring.
*. Round Trip: Ensures that incoming requests are handled by the server with the fastest response time. ConnectControl ascertains the response times of the servers in the group at a user-defined interval, whereupon the gateway executes a series of ICMP echo requests (pings) and reports which server has the shortest average round trip time. ConnectControl then directs the service request to that server. The round trip method is a good choice if there are large variations in the traffic load on your network or when load balancing over WAN connections.
*. Round Robin: Assigns service requests to the next server in the sequence. The round robin method provides optimal load balancing when the load balanced servers all have similar RAM and CPU and are located on the same segment.
*. Random: Assigns service requests to servers at random. The random method provides optimal load balancing when the load-balanced servers all have similar RAM and CPU and are located on the same segment.
*. Domain: Directs service requests based on domain name.
D. Assigns service requests to the next server in a series.
