Load balanced routers

Load balancing

— a feature found on models that have two or more connections to the Internet (and other external networks) — for example, multiple WAN ports, or a wired connector, supplemented by support for 3G / 4G mobile networks.

The general idea of balancing is to use several channels for external connection at the same time, dividing the load between them in one way or another. This improves connection efficiency by maximizing data transfer rates while avoiding unnecessary congestion. For example, a channel for online games can be separated from the rest of the connection, minimizing lags and reducing the likelihood of failures.

As for load distribution, it can be either automatic (when the router itself determines the optimal channel for each device, depending on the current traffic consumption), or manual (when specific channels are prescribed for different network devices, applications, or even types of traffic).
