Load Balancing Configuration Examples
Server Load Balancing Configuration Example
Network requirements
• As shown in Figure 44 , three servers Server A, Server B and Server C can provide HTTP services.
Server A has the highest hardware configuration, and Server B the second. It is required to make
these three servers provide HTTP services together, and all HTTP traffic is required to be filtered by
the firewall.
• Cluster provides HTTP service. Server load balancing should be applied.
• All traffic will pass the firewall: NAT-mode server load balancing (Responses in DR mode do not
pass the firewall).
• The performance of the three servers is different and therefore weighted round robin algorithm is
adopted.

Configuration procedure
NOTE:
•
Assume that Server A, Server B, and Server C have been configured (including routing information that
ensures normal packet forwarding). The configurations of the HTTP server are omitted here. Please refer
to related manuals.
• Assume that the IP addresses of the interfaces on the LB device and the zone to which they belong have
been configured. The following describes the configurations of load balancing in detail.
# Create real service group HTTPGroup.
• Select High Reliability > Load Balance > Server Load Balance from the navigation tree,
and you will enter the Real Service Group tab page. Then click Add to perform the following
configurations, as shown in
Figure 45 .
