Rule-based load balancing
You can configure rule-based load balancing on a port to fine-tune when and why packets are sent to which servers. To do that, right-click Port: PortNumber, then click Add rule and select the type of rule. This displays a pop-up window for configuring a rule of the chosen type). While there are a number of different rules available for MAC and NAT forwarding, we do not recommend using them for WebSphere Commerce scenarios like ours for the following reasons:
- All of our Web servers are capable of serving the same content.
- The Web server utilizes only static content. All dynamic content is generated by the application tier.
- Differences in capacity of the Web servers are managed by manager and the advisors (and, if you use them, the metric servers).
- Rule evaluation is generally expensive. When using content rules, Load Balancer also needs to collect all IP packets of a request before it can forward the request.
Refer to Load Balancer Administration Guide, GC31-6858, for detailed information about rule-based load balancing.
