This ratio remains stable across different scales. A global L3R alert can fire when any node's efficiency drops below a historical baseline, regardless of absolute traffic volume.
This is where comes in, and specifically, the Log10 Loadshare method—a technique used to mathematically smooth out traffic distribution based on server capacity. log10 loadshare
The actual traffic fraction ( f_i ) becomes: This ratio remains stable across different scales

: Effectively manage incoming and outgoing shipments tailored to branch-specific goals. Intuitive Interface
| Algorithm | Best for | When to avoid | |-----------|----------|----------------| | | Identical servers | Any capacity skew | | Least Connections | Long-lived sessions | Short/stateless requests | | Power of Two Choices | Reducing queue time | No per-connection state | | Linear Weight (cap/RT) | Predictable linear scaling | High capacity disparity | | Log10 Loadshare | High disparity + sublinear scaling | Tiny clusters (<3 servers) |
Most modern load balancers support weight assignment:
