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
This section describes the load balancing features and implementation supported by the SPU.
6.3 Configuring Egress Link Load Balancing
On the network where multiple ISP egresses exist, you can configure egress link load balancing
so that links are selected dynamically and service reliability is improved.
6.4 Configuring Server Load Balancing
In a network where multiple servers are deployed, such as a data center, you can configure server
load balancing to load balance the processing of network services among multiple servers. This
improves service processing capabilities.
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 load balancing configuration examples. A configuration example
includes the networking requirements, configuration roadmap, operation procedure, and
configuration files.
