Figure 44 Statistics (II)
The statistics show that when Host requests songs from the server group, there are connections only
on Server A and Server B, and the total number of connections of Server A and Server B is in a
ratio of 1:1; when Host requests news from the server group, there are connections only on Server
C and Server D, and the total number of connections of Server C and Server D is in a ratio of 1:1.
The statistics is the same as the pre-configured policies and algorithm. Therefore, the Layer 7 server
load balancing function has taken effect.
IPv4 firewall load balancing configuration example
Network requirements
As shown in Figure 45, two firewalls Firewall A and Firewall B each are connected to internal network
and Internet through an LB module to balance load between the two networks to enhance network
performance.
Firewall load balancing is adopted. LB module A operates as the level 1 LB module, and LB module B the
level 2 LB module.
