About This Chapter
Load balancing is a cluster technology that load balances special services such as network
services and network traffic among multiple links or network devices, for example, servers and
firewalls. The load balancing technology improves the service processing capabilities of
networks and ensures high reliability of services.
6.1 Load Balancing Overview
This section describes the background, classification, and basic concepts of load balancing.
6.2 Load Balancing Features Supported by the SPU
The load balancing features supported by the SPU and the implementation principle are as
follows.
6.3 Configuring Egress Link Load Balancing
On the network where multiple ISP egresses exist, you can configure egress link load balancing
so that the link can be selected dynamically and the reliability of services is improved.
6.4 Configuring Server Load Balancing
In the networking where multiple servers are deployed such as the data center, you can configure
server load balancing to load balance network services among multiple servers for processing.
In this manner, service processing capabilities of servers are improved.
6.5 Configuring Firewall Load Balancing
On a network where multiple firewalls exist, you can load balance network traffic among
firewalls in a group. In this manner, the burden of each single firewall is reduced and the network
processing capability is improved.
6.6 Configuration Examples
This section provides several configuration examples. A configuration example includes the
networking requirements, configuration roadmap, operation procedure, and configuration files.
