Lightboard Lessons: Local Traffic Manager Load Balancing Algorithms

[JRahm]

This article covers all the built-in load balancing algorithms available for BIG-IP Local Traffic Manager. They are grouped into three episodes of Lightboard Lessons in the following playlist.

If you want to review each algorithm directly rather than sitting through 30 minutes of my face to find the one of interest, you can link from the list below.

• Round Robin (part 1 at 1:05)
• Ratio (part 1 at 1:59)
• Ratio Session (part 1 at 5:30)
• Dynamic Ratio (part 1 at 7:32)
• Least Connections (part 2 at 2:16)
• Ratio Least Connections (part 2 at 3:57)
• Weighted Least Connections (part 2 at 6:02)
• Least Sessions (part 2 at 8:51)
• Fastest (part 3 at 0:22)
• Observed (part 3 at 3:09)
• Predictive (part 3 at 6:20)
