Welcome to the Server Load Balancing Wiki Project

"Knowledge is power, for real" - Astronaut Jack Austin

This is a wiki documentation site for discussion of server load balancing and related technologies. Such devices include:

• Server Load Balancers (also known as application directors/appliances/etc.)
• SSL Accelerators
• Global Server Load Balancers

Load Balancer Network Architecture

One of the biggest issues with load balancers are how they fit into a given network infrastructure. There are a couple of different ways that a given load balancer, depending on the vendor, can fit into a given network. One-armed, two-armed, multi-armed, route-path, bridge-path, these are all different ways load balancers can be implemented.

• Network Architecture Types
  • One-armed, route-path
  • DSR (Direct Server Return)

• Do you need to have a load balancer with Gigabit?
• You should know that there are really two load balancer markets.

Troubleshooting Corner

• Take a look at the Four-step NAT page to see how load balancing is technically done.
• Here's a Perl script for testing end-to-end connectivity with different source IP addresses on BIG-IP's Version 4.x.
